| Sponsorships.ai | Book a Sponsor | |
|---|---|---|
| What it is | A sponsorship marketplace and storefront for newsletters, podcasts, YouTube and events | An outreach service that pitches brands for newsletters |
| How you get sponsors | You list your audience and rate card; brands browse and reach out, and you can pitch the open opportunities brands post | It emails the brands that sponsored newsletters like yours and introduces you when one replies |
| Price to you | A paid membership: Starter $15 a month ($90 a year), Creator $19.50 a month billed yearly | $20 in free credits (200 emails), then 10¢ per email sent, initial emails and follow-ups |
| What it takes from your deals | 0% commission: payment goes between you and the brand, and it never touches the money | No commission, no rev-share |
| Free way to start | None: its pricing page says every plan is paid | $20 in credits (200 emails); card at checkout, no trial |
| Who can use it | Every format, newsletters included, with no hard minimum audience | Newsletters on any platform, no subscriber minimum; adult newsletters are refused |
| Who does the selling and the paperwork | You list, reply and close; it gives deal, deliverable and invoice tracking | Book a Sponsor, from its own mailboxes and domains; you read the pitch and can block any brand |
| Where it falls short | No free plan, no guarantee of deals or income per its FAQ, and the rates and audience figures are what each creator publishes | The pitches are cold email, so most brands won't answer, and each reply still needs you to close the deal. At the default 50 new brands a day it costs $5 a day, up to $10 with follow-ups, weekends included, so the $20 credit lasts 2 to 4 days. It takes no bookings or payments and works for newsletters only. |
When Sponsorships.ai is the better pick

When Book a Sponsor is the better pick
