Should You Stay on Substack?

Stick with Substack if the recommendation network drives a large chunk of your growth, community comments are central to your brand, and you’re okay with revenue sharing. Otherwise, running the math on a flat‑fee platform typically pays off after $1,000–$3,000/mo in subscription revenue.

Migration Game Plan

Export your Substack CSV (free + paid subscribers).
Clean your list—remove bounced & dormant emails.
Import into your new tool, preserving tags for free vs paid if possible.
Set up DKIM & SPF to protect deliverability.
Point your custom domain (or subdomain) to the new platform.
Announce the move 7 days in advance, then again on launch day.

Final Word

Substack sparked the creator‑newsletter renaissance. But in 2025, you have a buffet of platforms optimised for AI content, automation, full‑stack marketing, and zero revenue tax. Test two or three contenders—most offer free trials—and go with the one that feels invisible while you write.

Happy publishing!
