LetterBid - Newsletter Sponsorship Platform
LetterBid is a newsletter sponsorship platform that connects brands with newsletter publishers. It makes it easier for brands to find the right newsletters, book advertising placements, and manage sponsorship campaigns, while helping publishers turn their audiences into revenue.
Brands can explore newsletters across different industries, compare audience sizes and engagement, browse sponsorship packages, or send custom offers directly to publishers. They can book individual placements, arrange recurring sponsorships, or run campaigns across multiple newsletters, all from one platform.
For newsletter publishers, LetterBid provides everything needed to manage and grow a sponsorship business. Publishers can create their own public storefronts, showcase their audience statistics, set their sponsorship prices, and create packages for different advertising placements. They can also receive offers, negotiate deals, manage bookings, and track their earnings.
LetterBid also makes sponsorships more transparent and secure. Publishers can verify their newsletter statistics, brands can see prices upfront, and both sides can agree on the details before confirming a booking. Payments are held until the sponsorship is delivered and approved, helping protect both parties.
Getting started with LetterBid is free for both brands and newsletters.
