Built by Newsletter Operators, for Newsletter Operators

Selling newsletter sponsorships is a real business — but most operators run it like a side quest: prospects in a spreadsheet, negotiations lost in an inbox, publication dates in a personal calendar, and invoices sent whenever someone remembers.

Sponsley covers the whole sponsor cycle in one place: prospecting, pipeline, ad-slot inventory, creative deadlines, invoicing and payment tracking. Less admin, fewer dropped deals, better rates.

We're a small independent team in early access, working directly with our first newsletter operators. If that sounds like you, we'd love to talk.
