Ad copy library

Sponsorgap now features a growing Ad Copy Library where you can browse real sponsor messages and ad creatives from top newsletters. See what works, get ideas, and write better pitches faster.

Ad Calendar

A bit inspired by dividend calendars, we’ve built a ad calendar so you can stay on top of who's spending. The new Ad Calendar shows you the top sponsors each month — so you can spot trends, identify active advertisers, and know exactly who’s investing in newsletter ads right now. Perfect for timing your outreach and finding high-intent leads.

What else are we working on? We are slowly adding also podcast sponsors to our database, improving our database filter functionality and adding advanced ai metrics to each sponsor.
