What digest emails are
A digest email summarises recent activity or content from a service. It collects updates into a single message, reducing inbox noise. These emails typically aim to re-engage users with relevant information they might have missed.

What 88 of them actually do
Digest emails are a common retention strategy for many brands. We collected 88 such emails from 45 distinct sending brands, showing this is a widely adopted format. 99% of the digest emails we collected serve a retention lifecycle stage. I am hoping a daily or weekly digest to all users will work as a retention tool.
Most digest emails prioritise function over elaborate design. A utilitarian design style makes up 55% of the emails we collected. Only 2% carry a hero image, showing little focus on visual flair. Most are monochrome, at 83% of the collected emails, indicating a preference for simple, clean aesthetics.
Digests are typically text-heavy and single-column. We found 68% of emails were text heavy. 75% use a single column layout, with another 20% appearing as plain text. This suggests a focus on delivering information efficiently. Our daily digest for users would be a good thing because it will show if you're not suddenly sending.
Digests often present multiple engagement opportunities. The median number of calls to action per email is 6, indicating a desire to drive multiple types of engagement. Only 11% of emails contain exactly one call to action, showing brands typically offer several paths forward. Most digests maintain a neutral tone, accounting for 69% of the examples we reviewed.
Subject lines are usually descriptive, with some personalisation. 65% of subject lines are descriptive, clearly stating the email's content. About a third of all digest emails (33%) address the recipient by first name, indicating some level of personalisation. I’ve put weekly 1-2 line AI summaries into user digest emails, and monthly bigger review stats. It seems useful for me for obooko so far.
None of this helps if the send never lands, which is a promotional email problem rather than a design one.
