What’s the easiest way to sell sponsorships in your newsletter? Most publishers would tell you to start with the brands that have already advertised in other newsletters. These are the companies that not only understand the value of newsletters, but are also actively allocating marketing budget toward the medium.

But here’s the problem: there are thousands upon thousands of newsletters out there and no standardized ad units. This means that the only way to have a comprehensive picture of who’s advertising in newsletters is to subscribe to them all and then open them, one by one.

Or you can just save yourself time and check the spreadsheet below. I subscribed to hundreds of the most popular newsletters across a wide range of B2B and B2C niches and tracked 3,350 sponsorships.

Here are the specific things I tracked:

  1. The date I logged the sponsorship.

  2. The name of the newsletter. When possible, I linked to the individual edition where the sponsorship appeared so you can view the ad copy yourself.

  3. Each sponsor. I made sure to link to the advertised landing page for the brand so you can best understand its marketing goals.

  4. The niche/category.

The sponsorships were added in reverse chronological order. Here’s what it looks like:

The entire newsletter sponsorship index can be accessed in a searchable spreadsheet
