Email Marketing Strategy: What Most Brands Get Wrong

Electronic mail marketing, more commonly called email marketing, is the practice of sending targeted messages directly to a subscriber’s inbox to build relationships, drive conversions, and retain customers over time. Done well, it consistently outperforms most other digital channels on a cost-per-acquisition basis. Done poorly, it trains your audience to ignore you.

The mechanics are straightforward. The strategy is where most brands quietly fall apart.

I want to be direct about something before we go further. Most articles on this topic spend the first third explaining what email marketing is, as if the reader has never opened an inbox. You have. So instead of padding this out with definitions, I want to focus on what actually separates programmes that generate revenue from ones that generate unsubscribes.

Why Email Still Outperforms Channels That Get More Attention

There is a persistent tendency in marketing to chase the new thing. I have watched it happen across two decades: the industry moves its attention to whatever platform or format is generating the most conference talks, and email gets quietly deprioritised as something the operations team handles. Then the brands that stayed disciplined about their email programmes quietly outperform everyone else on retention and lifetime value.

Email has a structural advantage that no social platform can replicate: you own the relationship. When Facebook changes its algorithm, your organic reach drops. When a platform loses cultural relevance, your audience migrates and you start again. When you build an email list properly, you have a direct line to people who have actively opted in to hear from you. That is a fundamentally different commercial asset.

this clicked when early, in a way that had nothing to do with email specifically but everything to do with owned channels. In my first marketing role around 2000, I wanted to build a proper web presence for the business. The MD said no to the budget. So I taught myself to code and built it myself. What that experience gave me, beyond a working website, was an instinct for owned infrastructure. Platforms you control are worth building, even when they are unglamorous. Email is the clearest expression of that principle in modern digital marketing.

The other structural advantage is intent. Someone who has subscribed to your list and opened your email is in a fundamentally different mental state from someone who scrolled past your ad on a feed. The inbox implies attention, or at least the possibility of it. That is worth something, and the economics tend to reflect it.

If you want to understand how email fits into a broader channel mix, the Content Marketing Institute’s channel framework is a useful reference point for thinking about where owned, earned, and paid channels each play a role.

What Does a High-Performing Email Programme Actually Look Like?

Strip away the platform features and the automation workflows and the AB testing dashboards, and a high-performing email programme has three things working simultaneously: a clean, engaged list; a clear value proposition for every send; and a coherent strategy connecting individual emails to broader commercial goals.

Most programmes have one of these. Some have two. Very few have all three operating at the same time.

Email marketing sits within the broader discipline of content marketing, and the same principles apply: if you are not providing genuine value to the reader, you are just adding noise to their day. The brands that treat email as a broadcast tool, sending the same message to everyone on the list whenever they have something to promote, are the ones whose unsubscribe rates climb steadily until the programme becomes economically marginal.

The brands that treat email as a conversation, where different subscribers receive different messages based on what they have done and what they care about, build something that compounds over time. The list becomes an asset rather than a liability.

How Do You Build a List That Is Actually Worth Having?

List building is one of those areas where marketers consistently optimise for the wrong metric. The goal is not a large list. The goal is a list of people who want to hear from you and are likely to take action when they do. Those are different things, and conflating them is expensive.

Purchased lists are a waste of money in virtually every scenario I have encountered. You are emailing people who have no idea who you are, which tanks your deliverability, which damages your sender reputation, which makes it harder to reach even your legitimate subscribers. The short-term volume gain is not worth the long-term infrastructure damage.

Incentivised opt-ins require careful thought. Lead magnets, discount codes, and content downloads can build a list quickly, but they attract people who want the incentive, not necessarily people who want a relationship with your brand. If your lead magnet is a discount code, you have built a list of discount seekers. That has a specific commercial value, but it is not the same as building an audience.

The most durable lists are built through consistent content that gives people a genuine reason to subscribe. A newsletter with a clear editorial perspective. A content programme that covers a specific topic with real depth. Something that makes subscribing feel like gaining access rather than giving up a data point. This is why building a blog and building an email list are strategies that reinforce each other: the content gives people a reason to subscribe, and the email list gives you a direct channel to bring them back.

Double opt-in is worth using, even though it reduces initial conversion rates. The people who confirm their subscription are more engaged, more likely to open, and less likely to mark you as spam. The list is smaller and better. That trade is almost always worth making.

List hygiene matters more than most marketers acknowledge. Inactive subscribers drag down your engagement metrics and, more importantly, your deliverability. Running re-engagement campaigns for dormant contacts and then removing those who do not respond is not admitting defeat. It is good list management. A list of 20,000 engaged subscribers will consistently outperform a list of 80,000 mixed-quality contacts.

What Is the Right Segmentation Strategy for Email?

Segmentation is where email marketing gets genuinely interesting, and where the gap between average programmes and excellent ones becomes most visible.

Demographic segmentation, splitting your list by age, location, job title, or industry, is a reasonable starting point. But it is a blunt instrument. Two people with identical demographic profiles can have completely different relationships with your brand and completely different purchasing intentions. Demographic data tells you something about who someone is. Behavioural data tells you what they are actually doing.

Behavioural segmentation uses actions as the trigger for communication. Someone who has visited your pricing page three times in two weeks is telling you something. Someone who opened your last four emails but never clicked is telling you something different. Someone who purchased once six months ago and has not been back is a third distinct conversation. Treating all three the same way is a strategic failure.

The segments that tend to produce the most commercial value are:

• New subscribers in the first 30 days, where the welcome sequence sets the tone for the entire relationship
• High-engagement subscribers who open and click consistently, who are your warmest audience for new product or service announcements
• Past purchasers at various intervals, where the communication shifts from acquisition to retention and upsell
• Dormant subscribers who have not engaged in 90 or 180 days, where the goal is re-engagement or clean removal
• Abandoned cart or abandoned browse contacts, where the purchase intent is high and the timing of follow-up is critical

The sophistication of your segmentation should match the sophistication of your data infrastructure. There is no point designing twelve behavioural segments if your CRM cannot reliably populate them. Start with three or four clean segments you can actually execute, and build from there.

For teams managing complex email programmes alongside other marketing channels, the financial and operational infrastructure behind the scenes matters too. I have written elsewhere about accounting for marketing agencies, and the same principle applies internally: if you cannot track the cost and revenue attribution of your email programme with reasonable accuracy, you cannot make good decisions about where to invest in it.

How Should You Structure Your Email Automation Sequences?

Automation is the mechanism that makes email marketing scalable without becoming impersonal. But most automation sequences are built around time intervals rather than intent signals, which is the wrong architecture.

A time-based sequence says: someone subscribed, so send them email one on day one, email two on day three, email three on day seven. The logic is purely chronological. A behaviour-based sequence says: someone subscribed and opened email one but did not click, so branch them into a different path from someone who clicked through to the product page. The logic is responsive to what the person actually did.

The welcome sequence is the most important automation you will build, and it is worth spending disproportionate time on it. This is the moment when a subscriber’s interest is highest and their attention is most available. A welcome sequence that delivers genuine value, introduces your brand with a clear point of view, and gives the subscriber a reason to stay engaged is worth more than any promotional campaign you will run in the next twelve months.

The structure I have seen work consistently across different industries and business models tends to follow this shape:

• Email one: immediate delivery of whatever was promised at sign-up, plus a clear statement of what to expect from the relationship
• Email two: your strongest piece of content or your most useful resource, sent within 24 to 48 hours while attention is still high
• Email three: social proof, case studies, or evidence that other people have found value in what you do
• Email four: a soft commercial message, introducing a product, service, or offer with low pressure and clear relevance
• Email five onwards: transition into your regular editorial cadence, with the subscriber now treated as an established contact rather than a new arrival

Post-purchase sequences are the second most valuable automation most brands underinvest in. The period immediately after a purchase is when trust is highest and the opportunity to extend the relationship is greatest. A sequence that acknowledges the purchase, provides useful information about getting the most from the product or service, introduces complementary offerings at an appropriate interval, and asks for feedback or a review will consistently outperform one-off promotional sends to the same audience.

I had a direct experience of how powerful well-timed, intent-driven communication can be early in my career at lastminute.com. We launched a paid search campaign for a music festival, relatively simple by today’s standards, and saw six figures of revenue within roughly a day. The lesson was not that paid search is magic. It was that when you reach people at the right moment with the right message, the commercial response can be immediate and dramatic. Email automation, done properly, is the same principle applied to owned channels: the right message, triggered by the right signal, at the right moment in the customer relationship.

What Makes an Email Subject Line Actually Work?

Subject lines receive a disproportionate amount of attention in email marketing content, and the advice is often contradictory. Use emojis. Do not use emojis. Keep it under 40 characters. Write longer subject lines that tell a story. Personalise with the first name. Never use the first name because it feels manipulative.

Most of this advice is context-dependent and therefore mostly useless as universal guidance. What works for a fashion retailer will not work for a B2B software company. What works for a weekly newsletter will not work for a transactional notification. The only reliable approach is testing against your own audience with enough volume to draw statistically meaningful conclusions.

That said, there are a few principles that hold across most contexts.

Specificity outperforms vagueness. “Three things to fix in your email programme this week” will consistently outperform “Email marketing tips” because it signals that the content has a defined scope and a defined payoff. The reader knows what they are getting.

Curiosity gaps work, but they erode trust if the email does not deliver on the implied promise. If your subject line suggests something revelatory and the content is generic, you have trained your subscriber to be sceptical of your subject lines. That is a difficult hole to climb out of.

Preview text is underused. Most email clients show a preview snippet alongside the subject line, and most marketers either ignore it or let it default to the first line of the email body, which is often a logo alt tag or a “view in browser” link. The preview text is effectively a second subject line, and treating it as one will improve open rates without any other changes to the email.

Sender name matters as much as subject line. People open emails from people and brands they recognise and trust. If your sender name is unfamiliar or inconsistent, the best subject line in the world will not save you. Consistency in sender name builds recognition over time, and recognition drives opens more reliably than any copywriting technique.

How Do You Write Email Copy That Actually Gets Read?

Email copy is not the same as web copy, and it is not the same as advertising copy. The context is different: the reader has chosen to open this message, which means they have already cleared the first hurdle. The job of the copy is to reward that decision and move them toward a specific action.

The most common mistake I see in email copy is writing for the brand rather than the reader. Long introductions about what the company has been up to. Extensive background on a product feature that the reader did not ask for. Promotional language that treats the subscriber as a transaction waiting to happen. None of this serves the person reading the email, and they know it.

The discipline of content-driven communication applies directly here: every email should have a clear reason for existing from the reader’s perspective, not just the brand’s. Why is this person receiving this message today? What are they getting from it? If you cannot answer those questions clearly before you write the email, you should not send it.

Structure matters more in email than in most formats because reading conditions are poor. People open emails on phones, in between other things, with limited patience. Front-load the value. Put the most important information in the first two sentences. Make the call to action clear and singular. One email, one action. If you ask for three things, you will get none of them.

Plain text emails often outperform heavily designed HTML emails for engagement, particularly in B2B contexts. This is counterintuitive to most marketing teams who have invested in email templates, but the reasoning is straightforward: a plain text email looks like a message from a person, and a heavily branded HTML email looks like a marketing communication. The former gets more attention in an inbox full of the latter.

This does not mean design is irrelevant. For e-commerce and consumer brands, visual presentation is part of the brand experience and often drives click-through rates on product-focused emails. The point is that design should serve the communication, not substitute for it.

What Metrics Should You Actually Be Tracking?

Email marketing generates more metrics than almost any other channel, which creates a specific risk: optimising for the metrics that are easy to track rather than the ones that matter commercially.

Open rate is the most commonly reported metric and one of the least reliable. Apple’s Mail Privacy Protection, introduced in 2021, pre-loads email content for Apple Mail users regardless of whether they actually open the email, which inflates open rates significantly for any list with a meaningful proportion of Apple Mail users. Open rate is now a directional signal at best, not a precise measurement.

Click-through rate is more reliable as a signal of engagement, because a click requires an actual human decision. Click-to-open rate, which measures clicks as a proportion of opens rather than total sends, gives you a cleaner read on content relevance for the people who did open.

Conversion rate, measuring the proportion of recipients who complete a desired action, is the metric closest to commercial reality. But it requires proper tracking infrastructure: UTM parameters on all links, goal tracking in your analytics platform, and ideally some form of revenue attribution that connects email sends to downstream purchases or sign-ups.

Revenue per email, or revenue per subscriber, gives you the clearest picture of the programme’s commercial contribution. If you are running an e-commerce operation or a subscription business, this is the number that should sit at the top of your reporting dashboard.

Unsubscribe rate and spam complaint rate are health indicators rather than performance indicators. A spike in either signals a problem with list quality, content relevance, or send frequency that needs addressing before it compounds. Spam complaint rates above 0.1% will start to affect deliverability, and deliverability problems are significantly harder to fix than they are to prevent.

I have spent time judging the Effie Awards, which evaluates marketing effectiveness across industries, and the pattern that emerges consistently is that the most effective programmes have clear measurement frameworks established before the campaign runs, not retrofitted afterwards to make the results look better. Email is no different. Decide what success looks like before you send, and measure against that definition.

How Does Deliverability Work and Why Does It Matter More Than Most Marketers Think?

Deliverability is the unglamorous infrastructure layer of email marketing, and it is where programmes quietly fail without anyone noticing until the damage is significant.

Deliverability refers to the probability that your email will reach the inbox rather than the spam folder or be blocked entirely. It is determined by a combination of technical factors and behavioural signals, and both require active management.

The technical foundations are non-negotiable. SPF, DKIM, and DMARC authentication records tell receiving mail servers that you are a legitimate sender authorised to send on behalf of your domain. Without these, you are asking mail servers to trust you on faith, and they will not. Setting these up correctly is a one-time technical task that protects every email you send from that point forward.

Sender reputation is built over time through consistent sending behaviour, low complaint rates, and high engagement. Internet service providers use engagement signals to assess whether your emails are wanted: if recipients consistently open, click, and reply to your emails, that signals legitimate communication. If they consistently delete without opening, mark as spam, or let emails sit unread, that signals the opposite.

This is why list hygiene connects directly to deliverability. A large list of disengaged subscribers is not just a vanity metric problem. It is actively damaging your ability to reach the subscribers who do want to hear from you. The engaged minority suffers because of the disengaged majority, and the solution is to remove the disengaged contacts rather than continue sending to them in hope.

Sending volume and cadence also affect deliverability. Sudden spikes in volume, going from 5,000 emails per week to 500,000 without warming up your sending infrastructure, will trigger spam filters regardless of content quality. If you are scaling your email programme significantly, do it gradually and monitor deliverability metrics throughout.

How Does Email Marketing Work for Franchise and Multi-Location Businesses?

Email marketing in franchise and multi-location contexts has a specific complexity that generic advice tends to miss entirely. The tension between brand consistency and local relevance is real, and it requires a deliberate structural approach rather than hoping individual locations will figure it out.

The brands that handle this well typically operate a hub-and-spoke model: the central marketing function creates the templates, the brand guidelines, the core content assets, and the automation infrastructure. Individual locations or franchisees can personalise within defined parameters, adding local offers, local events, or local contact information without being able to deviate from brand standards in ways that create inconsistency.

This requires the right technology infrastructure, specifically an email platform that supports multi-location management with appropriate permissions at each level, and a content management approach that makes it easy for local operators to customise without breaking anything. If you are working through the broader channel strategy for a franchise operation, the digital franchise marketing piece covers this in considerably more depth.

List ownership is a particularly sensitive issue in franchise contexts. Who owns the customer data, the franchisor or the franchisee? This is a commercial and legal question as much as a marketing one, and it needs to be resolved in the franchise agreement before the email programme is built, not after a dispute arises about who gets to mail the list when a franchise relationship ends.

What Role Does AI Play in Email Marketing Now?

AI has moved from a theoretical capability to a practical tool in email marketing over the past two years, and the honest assessment is that some applications are genuinely useful and others are solutions looking for a problem.

Subject line optimisation using AI is one of the more mature applications. Platforms can now generate and test multiple subject line variants at scale, using historical engagement data to predict which variants are likely to perform better for specific audience segments. This is a genuine efficiency gain over manual AB testing, particularly for high-volume programmes.

Send time optimisation, using machine learning to predict the optimal send time for individual subscribers based on their historical open behaviour, is another application that tends to produce measurable improvements without requiring significant workflow changes.

AI-assisted content generation is more nuanced. The tools are capable of producing serviceable first drafts, and for high-volume programmes where the alternative is not sending at all, they represent a real productivity gain. The risk is that AI-generated content tends toward the generic, and generic email content is precisely what erodes subscriber engagement over time. I have written about this tension in the context of AI content creation more broadly, and the same principles apply here: AI can help you produce more content faster, but it cannot replace the editorial judgment that makes content worth reading.

The Moz analysis of AI in content and SEO makes a point that applies equally to email: the tools are most valuable when they augment human judgment rather than replace it. Using AI to handle the mechanical aspects of email production while keeping human editorial control over strategy, tone, and audience relevance is the architecture that tends to work.

Predictive segmentation, using AI to identify which subscribers are most likely to purchase, churn, or respond to specific offers, is where the technology has the most significant commercial upside for sophisticated programmes. But it requires clean, well-structured data to function. Garbage in, garbage out applies to machine learning as much as it applies to manual analysis.

How Do You Integrate Email With the Rest of Your Marketing Stack?

Email does not exist in isolation, and treating it as a standalone channel is one of the more common strategic mistakes I see. The most effective programmes are integrated with the rest of the marketing stack in ways that create coherent customer experiences rather than disconnected communications.

CRM integration is the foundation. Your email platform needs to be talking to your customer database in real time, so that subscriber behaviour in email is visible in the CRM and customer behaviour in other channels can trigger email sequences. A customer who calls your support line should not receive a promotional email about the product they just complained about. That sounds obvious, but it happens constantly in organisations where the email programme operates independently of the customer service function.

Paid media integration creates some of the most commercially interesting possibilities. Suppressing recent email converters from paid acquisition campaigns avoids wasting budget reaching people who have already purchased. Using email subscriber lists as seed audiences for lookalike targeting on paid social extends the reach of your most valuable audience profile. Retargeting email non-openers with paid social ads delivers the same message through a different channel to people who missed it in the inbox.

Content integration means that your email programme and your content production are working from the same editorial plan rather than operating independently. The blog post goes out on Tuesday, the email promoting it goes out on Wednesday, the social posts go out across the week. The audience receives a coherent signal rather than disconnected messages. This requires a shared editorial calendar and a content management approach that treats email as a distribution channel for content rather than a separate content production operation. A well-configured content management system is what makes this coordination practical rather than aspirational.

The Content Marketing Institute’s planning framework is worth reviewing if you are trying to build this kind of integrated approach, because it addresses the organisational and process questions that most tactical guides skip over.

What Are the Legal and Compliance Requirements You Cannot Ignore?

Email marketing operates within a legal framework that varies by jurisdiction and carries real consequences for non-compliance. This is not an area where it is acceptable to be vague about your obligations.

In the UK and EU, the GDPR and the Privacy and Electronic Communications Regulations establish the rules for email marketing to individuals. The core requirements are: you need a lawful basis for processing personal data, which for most marketing email means explicit consent; you need to make it easy to unsubscribe and honour those requests promptly; and you need to be transparent about who you are and how to contact you.

In the United States, the CAN-SPAM Act is less restrictive than GDPR in some respects, operating on an opt-out rather than opt-in model for commercial email, but it still requires clear identification of the sender, a functioning unsubscribe mechanism, and no deceptive subject lines or sender information.

Canada’s CASL is among the most stringent email marketing laws globally, requiring express consent for most commercial electronic messages and imposing significant penalties for violations.

The practical implication is that if you are marketing to audiences in multiple jurisdictions, you need to understand which rules apply and build your consent and data management processes to meet the most stringent standard you are subject to. This is not just a legal risk management exercise. It is also good practice: programmes built on genuine consent consistently outperform those built on ambiguous or coerced opt-ins, because the subscribers actually want to be there.

Document your consent processes. Know where each subscriber came from, when they subscribed, and what they consented to. If you cannot answer those questions for your current list, that is a problem worth fixing before it becomes a regulatory one.

How Do You Build an Email Strategy That Connects to Business Outcomes?

This is the question that most email marketing guides avoid, because the honest answer requires acknowledging that email strategy cannot be designed in isolation from business strategy. The two have to be connected, or the email programme becomes activity without purpose.

Start with the commercial objectives. Not “increase email engagement” or “grow the list.” Those are programme metrics, not business objectives. The business objectives are things like: acquire new customers at a cost below a defined threshold, increase repeat purchase rate among existing customers, reduce churn in a subscription cohort, or generate qualified pipeline for the sales team. Email strategy should be designed to contribute to one or more of these, and the metrics you track should connect to them.

From the business objective, work backwards to the audience. Who are the people whose behaviour needs to change for this objective to be met? What do they currently believe or do, and what would they need to believe or do differently? What information or experience would move them in that direction? This is the brief for your email content, and it is considerably more useful than “we need to send a newsletter every two weeks.”

From the audience and the content brief, design the programme architecture: which segments receive which sequences, at what frequency, triggered by what signals. This is where the strategic work happens, and it is worth spending real time on before you start producing content or configuring automation workflows.

The HubSpot data on inbound marketing and list building is useful context here: the brands that build the most valuable email audiences tend to be the ones that have invested in content and inbound strategies that give people a genuine reason to subscribe, rather than those that have focused primarily on list acquisition tactics.

Review the programme against the business objectives quarterly, not just the email metrics. If open rates are up but revenue per subscriber is flat, something in the conversion architecture is not working. If list growth is strong but engagement is declining, something in the content or frequency is wrong. The email metrics are diagnostic tools, not endpoints.

Email marketing strategy is one piece of a larger content and channel picture. If you want to see how it fits into a broader strategic framework, the Content Strategy hub covers the full landscape, from editorial planning to channel selection to measurement.

What Separates the Email Programmes That Compound From the Ones That Plateau?

I have seen email programmes at both ends of this spectrum across the agencies and businesses I have worked with. The ones that compound share a few characteristics that are worth naming directly.

They have an editorial perspective. Not just content, but a consistent point of view that makes the emails recognisable and worth reading regardless of the specific topic. Subscribers know what they are getting and why they subscribed, and that clarity reduces the cognitive friction around opening and engaging.

They treat the list as an asset to be stewarded, not a resource to be extracted. The question is always “what value does this send create for the subscriber?” before “what do we want from this send?” That discipline produces better content and better commercial results over time, because subscribers who feel the relationship is reciprocal are more likely to act when you do make a commercial ask.

They test systematically. Not random AB tests on individual sends, but structured testing programmes that generate learnings applicable across the programme. What subject line formats work best for this audience? What send frequency produces the best engagement-to-unsubscribe ratio? What content types drive the most clicks? These questions have answers specific to each audience, and the only way to find them is to test with enough rigour to trust the results.

They evolve. The email programme that was right for the audience two years ago may not be right today. Subscriber preferences change, competitive context changes, and the programme needs to adapt. The brands that plateau are often the ones that found something that worked and stopped questioning it. The ones that compound keep asking whether what they are doing is still the right thing to be doing.

The Copyblogger analysis of content and audience building makes a point that resonates with what I have observed in practice: the brands that build the most durable audience relationships are the ones that consistently prioritise the reader’s experience over their own short-term promotional needs. Email is the channel where that principle is most clearly rewarded and most clearly punished when ignored.

The strategic thinking behind a strong email programme does not exist in isolation. It connects to your broader content approach, your channel mix, and your understanding of how your audience consumes information. If you are building or refining that broader framework, the Content Strategy hub at The Marketing Juice is a useful place to work through the connected decisions.
