Challenge: How to create personalized emails for 94 million users

Flo faced the challenge of managing its growing email marketing needs efficiently and cost-effectively. With over 94 million users opted into emails and an increasing reliance on email as a direct communication tool, Flo needed a solution to keep up with its ambitious plans. Email marketing was quickly becoming a vital channel for Flo to deliver personalized health insights, promote product features, and offer users the benefits of Flo Premium.

Flo needed a tool to streamline its email production, allowing it to maintain high-quality design and content. They were looking for a way to simplify collaboration among their team and reduce the approval chain, ensuring that they could respond quickly to user needs. Additionally, the need for visual consistency and engaging email designs that reflected Flo’s brand was critical.

This is where Stripo’s email builder became a valuable tool, allowing Flo to efficiently create visually appealing and highly targeted email campaigns.

Solution: 400 emails over nearly three years

At Flo, the email production process is a well-organized collaboration between the design and marketing teams, with Stripo playing a key role. 

Although Flo has a large team of designers, Stripo streamlines the email production process, allowing one person to handle the design phase efficiently: 

  1. The senior marketing copywriter is responsible for crafting the email copy and aligning it with the overall strategy and tone of voice. The copywriter first works in Figma with a mock-up, which the email designer then builds in Stripo.
  2. The senior email designer handles the design and build of all emails, ensuring that each one reflects Flo’s visual identity and messaging. 
  3. Other members of Flo’s wider marketing team often dip into Stripo files to make small tweaks. This is very helpful for speeding up processes and avoiding bottlenecks.
  4. After the email is built in Stripo, it is exported and uploaded to Flo’s bespoke content management system.

I have been using Stripo at Flo for nearly three years. At that time, I think I have created approximately 400 emails!

Results: What Stripo features help minimize the time for Flo email production 

Throughout their time using Stripo, Flo has encountered only minor challenges, which were quickly resolved thanks to Stripo’s responsive support team. When technical issues arise or Flo’s team faces difficulty executing a design, the support chat is their first point of contact. 

The team consistently provides fast and effective solutions, often offering code snippets or instructional videos to help bring their vision to life. This level of support has been invaluable in ensuring that their email campaigns run smoothly and meet the brand’s high standards.

Modular email design

One of the key benefits Flo has experienced with Stripo is the significant time saved in email production, particularly through the use of modules. This feature allows them to build email elements once and reuse them across multiple campaigns, cutting down on repetitive tasks and ensuring consistency. 

For example, Flo recently worked on a project involving personalized welcome emails that required the creation of 94 different versions. Using Stripo’s module feature, they could simply drag and drop prebuilt blocks, reducing what could have been a time-consuming process to just a few steps.

Last year, we worked on a project in which we created fully personalized welcome emails using 3x blocks based on user actions (what they had or hadn’t done at that point in their journey). I used the module feature in Stripo to build the different options, so when creating the 94 emails, it was simply a case of dragging and dropping the modules in. I don’t want to consider how long that would have taken without this feature!

Modules in the Stripo editor

Balance between design flexibility and accessibility

Additionally, Flo values Stripo’s balance between design flexibility and accessibility. The ability to edit code directly — whether by adding gradients, background images, or tweaking CSS — enables them to maintain creativity without sacrificing live text accessibility. This combination of features and support has made Stripo an essential tool for email marketing, offering both efficiency and flexibility in their workflow.

Note from the Stripo team: If you are using Stripo, you don’t need to worry about ensuring that HTML emails are optimized for screen readers, as all emails built with Stripo are already fully optimized.

Plans for using new features

While Flo hasn’t yet fully leveraged Stripo’s real-time co-editing or version history features, they recognize these tools’ potential to enhance their workflow further, especially as they refine their email strategy.

Inspirational example from the Flo team

Here are some inspiring examples from the Flo team created using the Stripo email editor. See how the design is consistent with the overall style of the application and site and filled with email features that allow you to increase conversions and engagement.

Email example 1: June Sale 2024

Our seasonal sale emails are especially successful for Flo. They combine a few psychological hooks, such as name personalization, time pressure, social proof, and unique visuals, which altogether create an engaging email experience.

Email example 2: The launch of our Guided Journey feature

This email campaign is Beth’s favorite, as it stands out from our usual content. The dark color palette sets the mood for the content, plus it has the added bonus of being dark mode compliant! Including GIFs in our emails always works well to grab attention and enables us to show multiple pieces of content without using more vertical space, which is a premium in emails.

Email example 3: The launch of our symptom checker for PCOS and endometriosis

This email was one of the first where I experimented with background images. Being able to directly edit the code in Stripo means that I’m not creatively restrained. I really enjoy researching HTML techniques and applying them to an email. It’s very gratifying when it all works successfully!
