SponsorGap - Find Newsletter Sponsors

The intelligence gap

Brands are spending. Most creators never find out.

Every week, brands allocate newsletter sponsorship budgets. Without intelligence you're guessing who to pitch. With SponsorGap you see spend trends, ad frequency, and verified contacts — in real time.
