Ads and sponsorships

Newsletter sponsorships and affiliate deals, not in-episode podcast ads. The publisher account is free; invite-only campaigns carry a 10% fee.

Who it is for

Podcast publishers with a meaningful email audience who want sponsorship and affiliate opportunities for the newsletter around their show.

Who it is not for

Creators looking for a verified reciprocal newsletter-swap service.

Starting price

Free for publishers; 10% fee on invite-only campaigns

The gotcha

This monetizes newsletters and related audiences, not podcast audio inventory. The pricing page labels paid publisher tiers inconsistently, so confirm those tiers before budgeting for them.

Swapstack focused on newsletter advertising and monetization, rather than reciprocal audience swaps. beehiiv announced its acquisition in September 2023.

The standalone site still offers account creation for publishers and advertisers. Publishers can use the marketplace without an access fee; Swapstack lists a 10% fee on invite-only campaigns.

The pricing page also shows Professional and Enterprise publisher prices while labelling those tiers as coming soon. Treat those paid tiers as unconfirmed until checkout or current terms make their availability clear.

Use it for the newsletter or content audience around a podcast. It is not a marketplace for inserting ads into podcast episodes.

Public plans

Publisher

Free; 10% on invite-only campaigns

Advertiser

10% of ad spend

Paid publisher tiers

Professional $30/month and Enterprise $200/month are displayed, but the same page labels them coming soon

A live standalone signup route and free publisher plan were verified. Paid publisher tier availability remains internally inconsistent on the official pricing page.
