Started my newsletter 188 days ago. Just passed 1800 subs.

Biggest traffic sources are Substack network, Twitter and Reddit.
I got recommended by a few bigger newsletters that led to more growth.
I want to start posting my articles to my own domain since Substack seems to struggle to rank in Google results.
Newsletter is https://mythicalai.com/
Damnn congrats!!! That's huge. Any advice for posting your work to Reddit? Having a hard time there -- certain subcommunities seem brutal on self promoters (which is fair enough). Did you have a preexisting following on Twitter? How are you engaging with the Substack network and what did you find worked best?
My own project still has less than 100 subscribers -- I'm an AI research scientist covering Internet culture, AI, and tech. Check it out here https://posttruth.substack.com/about if you feel so inclined and subscribe!

A bit of feedback for your Substack - I looked at the homepage and couldn't really tell what you are about. Are you doing a podcast? Are you recapping other interviews?
There was no articles that made me stop and want to click. So maybe work on the headlines to entice readers?
Good luck!
Hi, would you be open to do some cross promotion ?
My newsletter is www.kuration.substack.com
I looked at Kuration seems like you are doing daily tech news?
I don't know if there is a huge overlap between our audiences. I only write one a week and it is deep dive. I could be wrong however.
I dont mind cross promotion on one issue. We can try.
