A Simple Guide to Email Flows and How to Optimise Them

As we’ve mentioned before, email marketing isn’t dead. We’re using it every day and it still continues to be one of the most effective ways to connect with customers. We were recently auditing a client’s email flow and it reminded us just how critical they are for subscriber engagement and conversion.

So, what is an email flow? Why is it important? How do we set one up? Let’s dive in!

What is an email flow?

An email flow is a sequence of emails automatically sent to subscribers when they’ve decided and consented to sign up for communication. This could be triggered by signing up for a newsletter, downloading a guide or making their first purchase.

Email flows are purposeful and contextual. When someone abandons their shopping cart or celebrates their birthday as a customer, they are triggered to enter into a specific flow designed for that exact moment. This ensures subscribers receive the right message at the right time. Especially, when they’re personalised, it creates a much better email experience overall.

Example of an email flow

Why are email flows important?

Email flows are important as it helps guide subscribers through the journey towards products, services or categories that align with their interests and behaviours. Rather than overwhelming new subscribers with the entire collection or catalogue or services, flows gently guide them towards what’s most relevant.

For example, if someone signs up after browsing your women’s cyclingwear collection, your welcome flow can gradually introduce them to fitted shorts and tops, essential accessories for the ride, or layering guides for different weathers. This targeted approach will increase the likelihood of engagement and conversions because you’re guiding subscribers towards what they’re already interested in.

How do we set up email flows?

A lot of email platforms have templates to help you set them up. For example, Klaviyo has a ton of options to choose from.

Creating email flows doesn’t have to be complicated. Here are some quick, easy steps to get started:

1. Defining your email trigger: whether that’s signing up for your newsletter, abandoning a cart or creating a thank you flow, make sure it’s clear what your email flow is about.
2. Plan for your subscriber journey: map out what you want them to know and what you are trying to communicate in these emails. Whether that’s promoting a certain product, service or category, have a clear goal in mind.
3. Set up flow logic: make sure there is enough time in between emails. We often forget about the timing between each email when we create the flows, but this spacing is crucial for maintaining engagement without overwhelming subscribers.
4. Write compelling content: It’s important to write compelling content, especially at the beginning stages of your email flows. This keeps subscribers interested in what you have to offer as it’s the beginning of building that relationship. Plus, make sure your emails are well linked. Every image or text should link to the correct product or page.
5. Implement tracking: We often forget to set up proper tracking, but this is essential. This way, you can monitor open rates, click-through rates and conversions and the important metric, unsubscribe rates for each email in your flow. This data is crucial for optimisation later.

Optimising email flows

Once your flows are live and running for some time, you can optimise them. Here are key areas to focus on:

1. Implement Smart Sending: This is critical.You don’t want to overwhelm your subscribers with a ton of emails. The best practice is ensuring you skip subscribers who have received emails within a certain timeframe, such as the 2 hours. This helps prevent your emails from going to spam or junk folders, as sending too many emails too quickly can trigger spam filters. It also reduces the likelihood of unsubscribes, especially when you have multiple flows that might tiffer simultaneously. On Klaviyo, there is a toggle on email flows to help enable this.

Example of smart spending

1. A/B testing: We can A/B test different parts of your flows, including subject lines, send times, call to action buttons. Focusing on testing one element at a time can help clearly identify what is driving results. Even if that’s just small improvements on open rates or click-through rates it can make a difference. If something isn’t working then, it can easily be swapped out.
2. Segmentation:  Depending on what business, you can segment your subscribers down even further. For example, customers who have spent £500 in the past 3 days could be selected and put into their own VIP flow. They might receive slightly different offers or deals compared to customers who have spent less, creating a more tailored experience based on their value to your business.

Final thoughts on email flows

People are choosier than ever about the emails they open. Email flows help your brand cut through the noise by sending the right message at the right time.

Email flows are more than automated sequences. They guide subscribers through a journey that feels personal and worthwhile. When done well, flows create a win-win: your audience feels valued, and you build stronger connections with them.

Start with the basics like welcome emails, abandoned cart reminders, and post-purchase check-ins. Add more as you learn what works. Keep it simple, keep it relevant, and you’ll turn your emails into something subscribers actually look forward to.

So, if you haven’t already, start mapping out your flows and optimise them thoughtfully. And if you’d like a hand getting started, we’re always here to chat.
