# What are the best sponsorship platforms for a B2B newsletter?

Book a Sponsor and SponsorGap meet all five criteria below: both reach B2B buyers with no list-size minimum and no cut of your deals, and Book a Sponsor sends the pitches for you on a plan from $19 a month while SponsorGap's self-serve plans give you the list from $39 a month. Passionfroot, the network built around B2B brands, meets four: it takes 15% of the deals it brings.

**We make Book a Sponsor, number 1 below.** We read each option's own pages on 8 October 2026 and 20 October 2026 and scored it on the criteria below, which we chose before scoring. We didn't sign up for or test the others, and each links to its source.

Book a Sponsor (bookasponsor.com) pitches brands to sponsor newsletters.

## How we ranked them

Criteria, chosen before scoring: its own pages name B2B brands, B2B audiences or B2B categories; no list-size minimum stated; takes no percentage of your deals; publishes a price; brings or pitches sponsors for you. Each is a yes or no from the vendor's own pages, and the rank is the number of yeses. We make Book a Sponsor and it meets all five.

## B2B newsletters run sponsors 2.6 times as often

In Book a Sponsor's reading of 4,357 newsletters in eight niches (10 July 2026 to 8 October 2026), 27.1% of the 1,365 AI, developer, tech, marketing and business newsletters ran at least one paid sponsor ad, against 10.5% of the 2,992 health, food and culture newsletters. B2B brands already buy this inventory, so the question for a B2B newsletter is how to reach them, not whether they buy.

| Niche | Newsletters | Ran a paid ad | Share |
| --- | --- | --- | --- |
| **AI** B2B | 388 | 121 | **31.2%** |
| **Developer** B2B | 34 | 11 | **32.4%** |
| **Tech** B2B | 306 | 94 | **30.7%** |
| **Marketing** B2B | 180 | 53 | **29.4%** |
| **Business** B2B | 457 | 91 | **19.9%** |
| **Health** | 751 | 90 | **12.0%** |
| **Food** | 508 | 61 | **12.0%** |
| **Culture** | 1,733 | 162 | **9.3%** |

Newsletters with 5+ issues read in the 90 days to 8 October 2026 that print a list size; politics, foreign-language and adult newsletters out. An ad counts when it is printed in the public text of an issue, so every share is a floor.

## Questions

### What is the best sponsorship platform for a B2B newsletter?

On these criteria Book a Sponsor and SponsorGap, tied at five of five, then Passionfroot at four. Book a Sponsor pitches brands for you on a plan from $19 a month; SponsorGap sells the brand list from $39 a month and pitches for you on its $999 managed plan; Passionfroot is free and built around B2B brands but takes 15% of the deals its network brings.

### Do B2B brands sponsor newsletters?

Yes. In our reading of newsletters from 10 July 2026 to 8 October 2026, 27.1% of 1,365 AI, developer, tech, marketing and business newsletters ran at least one paid sponsor ad, against 10.5% of 2,992 health, food and culture newsletters.

### Is Paved good for a B2B newsletter?

Only above its minimums: Paved's bookings need 50,000 subscribers and its pay-per-click network 1 million monthly impressions, and it publishes neither fee rate. Under that, a B2B newsletter has to pitch brands or use a marketplace with no minimum.

### What do B2B newsletters charge for a sponsorship?

It depends on list size more than niche. See [what newsletters charge by list size](https://bookasponsor.com/newsletter-sponsorship-rates) and the [sponsorship calculator](https://bookasponsor.com/newsletter-sponsorship-calculator).
