About

CrossLetter is designed to connect email senders looking for mutual growth, while attracting solid sponsors.

Because cross-promotion is one of the fastest ways to grow a newsletter, CrossLetter has been designed to connect newsletter senders, brands and sponsors in a free, effective and data-driven way.

It's simple:

- Sign up and list your newsletter

- Set parameters for cross-promotion and sponsorship

- Browse through the best newsletters that fit your audience

- Reach out, make a connection and start collaborating!

If you're a sponsor looking for great newsletters to sponsor or build relationships with, this is also the space for you.

- Sign up and launch your sponsorship profile (for brands and newsletters)

- Create a collection of newsletters you'd like to sponsor

- Connect with operators who fit your target audience profile

- Launch campaigns you'd like to book, and list what you're willing to pay

CrossLetter is also manually vetted for quality and control, so each newsletter and sponsor goes through checks by an actual human, to verify their metrics, legitimacy and more.
