Book a Sponsor - 2026 Pricing, Features, Reviews & Alternatives

Book a Sponsor is a cloud-based, done-for-you sponsor outreach service built for newsletter operators and creators across all list sizes and niches (excluding political and adult content). Operators submit a newsletter URL; the service reads published issues to identify sponsored placements across a database of 3,576+ newsletters and 6,560+ brands, matches the submitted newsletter to similar newsletters by niche, and surfaces the brands that have already purchased sponsorships in those newsletters. No software installation or technical setup is required, and the service integrates automatically with Substack, beehiiv, Kit, Ghost, Buttondown, Mailchimp, and any newsletter with an RSS feed.

Once matching brands are identified, Book a Sponsor locates the decision-maker responsible for sponsorship spend — founder, CEO, head of growth, marketing, or partnerships — and verifies each email address before outreach begins. A personalized cold email pitch is drafted for each brand based on the newsletter's niche and audience profile. Pitches are sent daily (25 to 100 per day, defaulting to 50, adjustable via a dashboard slider) from proprietary warmed mailboxes on dedicated sending domains, keeping the operator's own email infrastructure untouched. Follow-up emails are included in the send cadence. Brands that opt out are added to a global suppression list shared across all clients for 21 days following a negative reply. The sponsor database is rebuilt daily, with new brands added weekly as buying activity is detected in the operator's niche.

Positive replies are routed directly to the newsletter operator or forwarded to a designated booking page; the operator closes the deal. Pricing is pay-per-email-sent at $0.10 per send (initial and follow-up), with no commission, no revenue share, and no per-deal fee. New accounts receive 200 free email sends ($20 in credits) with no credit card required. A 30-day money-back guarantee applies if no sponsor reply is received within the first month.
