We found 979 ads from 310 companies in marketing newsletters, from March 2023 to October 2026. Each one links to the email it ran in.
The main finding
“41 companies advertised in more than one marketing newsletter, yet regular advertisers hold only 7% of the spots, so most dates are up for grabs.”
The first thing the report tells you. Every number in it links back to a real newsletter email.

The biggest newsletters at a glance
Here are the two biggest. The report profiles every newsletter like this, with the price and how to book wherever they publish it.
| Newsletter | Ads we found | Companies | Seen | Readers* |
|---|---|---|---|---|
| Marketing Brew | 380 | 123 | 2024–2026 | Readers not stated |
| STACKED MARKETER | 158 | 57 | 2026 | Readers not stated |
*Readers as stated by each newsletter. We count ads we found, not money spent or results.
Ads over time
Ads we found in Digital marketing newsletters, every six months.
More newsletters were tracked in recent periods, so part of the rise is wider coverage, not only more ads. Four newsletters have under three months of history. *2026 H2 is still in progress.
What kinds of companies advertise
Ads by the type of company that bought them.
Do advertisers come back?
86% of all the ads came from companies that advertised more than once. That’s a good sign those newsletters work for them.
- Once · 139 companies
- 2–5 times · 124
- 6+ times · 47
