Using email marketing flows to grow a loyal customer base

Email marketing flows are designed to deliver the right message to the right person at just the right time. By doing so, they help brands to build trust, win more conversions, and boost customer lifetime value.

If you run an online store, there are loads of email flows you can experiment with, but a few are absolutely essential if you want to retain more customers.

In this article, weโ€™ll explore some of the most valuable email flows for eCommerce brands. Weโ€™ll provide tips for what to include in each flow and how to make your emails more engaging and effective.

What are email marketing flows, and why are they important?

An email marketing flow is a series of automated and personalised emails that are sent out based on the subscriberโ€™s personal information or actions. Examples of actions that can trigger a flow include someone signing up to your website, abandoning their cart, or making a purchase.

Targeted email flows ensure that subscribers receive timely, relevant, and personalised communications tailored to their actions or preferences. Each email in the flow is designed to build trust and gently guide the subscriber towards a desired action.

According to email marketing experts Klaviyo, these flows generate up to 30 times more revenue per recipient than one-off campaigns.

The 3 most important email marketing flows for eCommerce

If youโ€™re ready to give email flows a shot but feeling unsure where to start, weโ€™ve got you covered. The following three flows are your core eCommerce email marketing flows. These are the ones that are most effective for building trust, encouraging conversions, and recovering lost sales. 

Welcome flow

The welcome flow is usually triggered when a new subscriber registers an account on your website or signs up for your email newsletter.

This is your opportunity to introduce your brand to new customers and make a good first impression.

The welcome series should tell new customers who you are and what your brand stands for. It creates an opportunity for you to build trust, introduce your brand values, and guide the customer towards making their first purchase.

What to include in your welcome flow:

  • Brand story and mission
  • Core products or categories
  • Awards and achievements
  • Customer reviews and testimonials
  • An exclusive discount code
  • A clear call to action (CTA)

By providing a discount code via a sign-up form, you can also gather extra information, like the subscriberโ€™s name or date of birth, to use in future flows.

Donโ€™t forget to include a clear CTA within every email โ€“ something like โ€œShow Nowโ€, โ€œBrowse Our Bestsellersโ€, or โ€œClaim Your Discountโ€ to guide subscribers towards the action you want them to take. Read our article all about how to write email marketing CTAs that actually work for more practical advice on this.

Abandoned browse flow

This flow is triggered when an existing subscriber browses your website but does not add anything to their cart. It is designed to pique their interest and bring them back to your website.

The idea is that if someone is already browsing your website, the intent is there; theyโ€™re just not ready to buy yet. By sliding into their inbox shortly after, you re-engage them with your brand, tempt them to revisit your website, and gently nudge them towards making a purchase.

What to include in your abandoned browse flow:

  • Products they viewed
  • Similar products
  • Your brandโ€™s USPs
  • User-generated content (UGC)
  • Shipping and returns information
  • A clear call to action (CTA)

Weโ€™ve found that including user-generated content like customer photos or reviews throughout this flow is an effective way to build trust and improve results.

Popular CTAs for this flow include โ€œStill thinking about it?โ€ or โ€œTake another lookโ€.

Abandoned cart flow

The abandoned cart flow is triggered when a subscriber visits your website, adds an item to their cart, but then leaves before checking out.

This action demonstrates a high intent to buy, and this flow focuses on reminding them about your brand and products, removing friction, and helping them overcome any last-minute reservations. It is the highest-performing email marketing flow there is.

What to include in your abandoned cart flow:

  • The exact item the subscriber left in their cart
  • Discount code (e.g. Free shipping)
  • Urgency messaging (e.g. Low in stock)
  • USPs
  • Payment options and delivery information
  • Social proof
  • Smart product recommendations

Sometimes, all it takes to seal the deal is a little incentive, like a discount code or free shipping. Time-limited codes can be even more effective as they add a sense of urgency. 

Later down the flow, you can ramp up the urgency with lines like โ€œlow stock alertโ€, โ€œsale ends at midnightโ€, or โ€œYour basket will expire soonโ€.

Treat this flow as an opportunity to address concerns that customers may have that have prevented them from making a purchase. Advertise the services you offer and the perks of shopping with you to provide reassurance. Things like โ€œFree returnsโ€, โ€œFree shipping over ยฃ30โ€, or โ€œWe offer Klarnaโ€ can help to nudge them over the line.

Other highly effective marketing flows to consider

The flows discussed above are a great starting point, but there are plenty more times when a carefully curated email flow can help to retain and strengthen a brandโ€™s relationship with its subscribers, drive more conversions, and increase average order value. Here are a few others to consider:

Post-purchase flow

Itโ€™s just as important to communicate with customers after theyโ€™ve purchased as it is before. Thank you flows are triggered when a customer buys something on your website. They are used to strengthen the customerโ€™s relationship with the brand and build trust.

Include a personalised thank you from your founder or team, tips for using or maintaining the product, or subtle upsell or cross-sell suggestions.

Review request flow

This email flow helps your business gather a collection of valuable customer reviews to use on its website, ads, social media, and future emails. It also assists in collecting customer feedback on your products and services, which can be used to improve and refine what you already offer.

Aim to start this flow about 7 days after the customer receives their order to give them time to try it out and resolve any issues with your customer service team.

Birthday flow

The birthday flow is triggered in the run-up to a subscriberโ€™s birthday. Itโ€™s a simple but effective way to surprise or delight your subscribers, building your relationship and adding value. 

Wishing them a happy birthday and offering a small discount or gift on their birthday helps to make them feel appreciated, boosting their loyalty to your brand.

Win back flow

This flow is sent to lapsed customers who havenโ€™t bought anything for a while. It is a subtle way of reminding them about your business and making them feel valued. This is your opportunity to entice them back and improve your customer retention rates.

Messaging like โ€œWe miss you!โ€, combined with information about your latest products, and perhaps an exclusive special offer, can tempt them back to your website.

Replenishment flow

The replenishment flow can be used in a couple of different ways. If a customer has bought a repeat-purchase product, this flow can be used to remind them when it might be time to reorder. 

Alternatively, it can be used after a purchase to suggest complementary products to a customer. For example, if they bought a Moses basket, you could set up a replenishment flow to suggest baby bedding sets, matching accessories, or nursery essentials.

Back in stock flow

This email flow is triggered when a customer has viewed or asked to be notified about an out-of-stock item, and that product arrives back in stock.

Use urgency in your messaging, like โ€œBuy now while stocks lastโ€, to help drive quick conversions.

Measuring the effectiveness of your email marketing flows

Once your email marketing flows are up and running, thereโ€™s still no time to rest on your laurels. 

Even if you have them professionally built, thereโ€™s always room for improvement. Tracking and measuring their performance is an ongoing process.

Klaviyo provides detailed yet easy-to-understand built-in analytics that enable you to monitor performance and continually refine and enhance your email flows.

No matter what tool you use to set up your email flows, the key metrics to monitor are always the same:

  • Open rate: Tells you how effective your subject lines are.
  • Click rate: Indicates how engaging your email content and CTAs are.
  • Conversion rate: Shows how effective the flow is at winning sales.
  • Revenue per recipient: Tells you how much revenue the flow is generating.
  • Unsubscribe rate: A high unsubscribe rate shows that your content, frequency, or timing needs a rethink.

Klaviyo also lets you A/B test emails within flows so that you can experiment with variations in copy, layout, or offers. Use these insights to iterate, refine, and grow your results over time.

You can compare your performance against Klaviyoโ€™s industry benchmarks to see how your flows stack up.
