What newsletter emails are
A newsletter email is a regular communication sent by a brand to its subscribers, typically containing updates, curated content, or promotional messages. Its primary purpose is to maintain engagement and build a relationship with the audience over time. These emails are usually part of a retention strategy, keeping existing customers informed and connected.

What 1,532 of them actually do
Newsletters are overwhelmingly focused on customer retention rather than acquiring new leads. Of the 1532 newsletters we collected, 93% target retention. Only 3% aim for acquisition. This shows brands use newsletters to keep existing subscribers engaged, not primarily to find new ones. Kam, who built our deliverability layer, notes, 'Between us we've built two email platforms, sent over 6 billion emails, and scale three technology companies.' We see this focus in the real emails sent by 728 distinct brands.
Most brands keep their newsletter design simple and text-focused, prioritising content over complex visuals. 64% of newsletters are text heavy, and 78% use a single column layout. This suggests a preference for readability over intricate visual elements. Only 5% of brands include a hero image. I believe your newsletter's voice is more important than its design; consistency of voice, not templates, builds audiences.
Newsletters often provide a range of options for the reader, rather than a single focus. The median newsletter carries five calls to action. Only 15% of the newsletters we collected feature exactly one call to action, indicating brands prefer to offer multiple paths for engagement within a single email. This often results in longer emails, with 47% being classified as long and 33% as medium length.
Instructional content dominates newsletter communication, reflected in subject line choices. 72% of newsletters use an instructional tone, guiding readers or providing information. This aligns with 75% of subject lines being descriptive, clearly stating what is inside. Brands like BuzzSumo and Zapier, which appear frequently in our corpus, often follow this instructional approach. I have found founder-written emails outperform corporate ones, suggesting authenticity resonates in this content-heavy format.
None of this helps if the send never lands, which is a email marketing problem rather than a design one.

Once the shape is right, the rest is getting the thing delivered.
