Started Newsletter 150 days ago, just crossed 1,400 subs.
Substack has driven 400 of those.

Substack (and maybe Beehiv) is the only newsletter platform that has worked on discovery features.
Others will send your emails. Substack helps you find new subscribers.
Seriously considering starting a newsletter soon so this post is super useful. Congrats on those numbers BTW!
Thanks for sharing, what's your substack about?
One weekly deep dive email about an AI tool or topic.

Thanks for sharing that.
Worth sharing - Lenny Rachitsky recommends Substack because it's minimalist approach and helps you focus on your writing quality, the ultimate driver of growth.
Hm, I've been writing over at https://gearsyfounder.substack.com/ about my journey to start a startup (so far just looking for a good idea) and it doesn't look like Substack's discovery has lead to any readers yet. Any thoughts?
