Looking for newsletters to sponsor

Hey Indie Hackers!

I'm running a marketplace called Microns where founders can buy and sell profitable bootstrapped startups.

I'm looking for newsletter creators to sponsor. Here are the main metrics that I care about:

1. Audience: founders, startups, online businesses.

2. Size: starting with 1k subscribers.

3. Open rate: 40% and higher.

4. Click rate: 5% and higher.

Share links to your newsletters here. And I'll DM you.

P.S. If you know someone you read, don't hesitate to mention.
