Anyone up for doing some newsletter cross promotion?

Started my first newsletter recently. https://rephrased.substack.com/

Basically solve topical programming challenges and learn the most exciting new tech. Great for developers looking for an edge in their next interview.

So far there has been a challenge to programmatically create a QR code and also one to build a voice controlled app.

Next edition will be building a video call app.

Numbers are looking good:

Approaching 300 people who have attempted the challenges
45 subs in less than 2 weeks
Over 800 views on the post version of the email

Now I know I have something of interest to people, I would love to spread the newsletter a bit wider.

Anyone running a programming/tech newsletter up for doing a bit of cross promotion. Would love to hear from you.
