How to Turn Email Marketing Into a Scalable Revenue Channel

Email marketing is routinely credited with returning somewhere between £10 and £36 for every £1 spent. It’s the figure every agency leads with, including the ones selling you email marketing, and it’s usually the first thing that falls apart when you look closely at the reporting behind it.

While most businesses will have some form of email marketing, many fail to utilise the channel (and its placement in the marketing funnel) effectively. The result of this? Reduced re-engagement from previous customers and a hit in that revenue total.

The difficulty is that the two metrics businesses tend to use to prove success – open rate and platform-reported revenue – happen to be the two most flattering figures available. Build a strategy on those and you can spend a year optimising something that was never really working.

If your email marketing currently feels like a tick-box exercise or a monthly newsletter nobody opens, there’s almost certainly revenue sitting unclaimed in your list.

So how do you tell if your email strategy is actually working and how do you scale your current approach to deliver tangible revenue and customer retention?

Segment Your Database and Target Precisely

One of the fastest ways to kill email performance is sending the same message to everyone. Every irrelevant email you send essentially encourages a subscriber to skim past the next one and eventually unsubscribe completely.

Emails should be relevant and personalised to the users who receive them. An important part of this is database segmentation. At a minimum, your email list should be split by:

• Customers vs prospects
• Past purchases/services used
• Stage of the buying process
• Active vs inactive subscribers.

How to Build a Segment in Your Email Platform

A segment within an email database is a dynamic group of subscribers defined by rules rather than a fixed list, so it updates itself as people’s behaviour changes.

Rules can draw on purchase history, engagement, customer status, or on-site activity – a segment might be “purchased in the last 90 days”, which you’d then exclude from a first-order discount campaign. Because segments are live, someone who buys tomorrow moves out of your prospect segment automatically, without anyone maintaining a spreadsheet.

Build Automated Flows

Automated flows are pre-built email sequences triggered when someone takes, or fails to take, a particular action. The great aspect of them is that you build them once and then run without further input.

Building these flows is one of the key strategies to make a marketing strategy scalable.

As an example, a well-built welcome flow generates revenue every day that new subscribers arrive, and its output grows as your list grows, without anyone doing more work. This aspect of email marketing can make a huge difference in ROI and sales volume. In fact, some of the highest-performing email campaigns are automated flows that run quietly in the background. These emails work because they’re triggered by behaviour. The message arrives at the moment the user is most likely to act.

At Talking Stick Digital, we build on Klaviyo, largely for the depth of its automation and segmentation logic.

Example Flows To Build

Below are some of the priority flows that we would recommend building to maximise email ROI:

• Welcome sequence – a short series introducing your brand and prompting a first purchase. Highest volume of eligible subscribers, so it usually pays back fastest.
• Abandoned cart or enquiry follow-up – recovers people who were already at the point of buying.
• Browse abandonment – catches interest earlier, where intent is softer, but volume is higher.
• Post-purchase and upsell – works on customers you’ve already paid to acquire, so the margin is better.
• Re-engagement – reconnects lapsed subscribers, and tells you which ones to stop emailing.

Balance Value & Sales

This is one pitfall we often see email marketing strategies fall into.

At face value it might seem sensible to push all your latest products/services in every email you send. In actuality, it can have the opposite effect and be one of the easiest ways to lose engagement.

Balancing value and sales increases revenue by protecting long-term engagement. Subscribers who feel constantly sold to are more likely to unsubscribe or stop opening emails altogether. By delivering value-led content alongside promotions and sales-based emails, businesses maintain higher open rates and stronger click-through rates, making sales emails more effective when you do send them.

Another benefit of sending value-based emails is that it will help to nurture that customer relationship and increase brand trust, which will help lead that user to make a purchase or convert.

Test & Optimise Your Email Campaigns

A/B testing is something we are strong believers in across all digital marketing channels. For email, A/B testing allows marketers to experiment with different versions of an email campaign to identify what resonates most with their audience. This could include testing subject lines, call-to-action wording, send times, or even the overall layout of the email.

By testing one variable at a time and monitoring performance metrics such as open rates, click-through rates, and conversions, businesses can continuously refine their email strategy. Over time, these incremental improvements compound, helping turn email marketing into a more consistent and effective revenue channel.

Email Marketing FAQs

How often should I send marketing emails?

There’s no one-size-fits-all answer. The right frequency depends on your audience, industry, and content quality. Quality & relevance matter more than volume; it’s better to send fewer, more relevant emails than frequent generic ones.

Can email marketing work for small businesses?

Yes. Email marketing is especially effective for small businesses because it’s affordable, scalable, and allows direct communication with customers.

What’s the biggest mistake businesses make with email marketing?

One of the biggest mistakes is sending the same message to the entire list. Lack of segmentation and relevance often leads to low engagement and missed revenue opportunities. Read our blog on common email mistakes and how to fix them to learn more.
