How to Stop Substack Emails
Quick answer: To stop Substack emails, open a recent Substack email and unsubscribe, then go to your Substack notification settings at https://substack.com/settings and switch off the categories you don't want. Substack controls its email by category, so one unsubscribe click usually stops only a single type. To clear the backlog, search from:substack in Gmail and bulk delete.
What Substack actually sends you
Substack sends individual publication posts and newsletters, Substack marketing and product emails, reading recommendations and digests, activity digests (replies, mentions, notes), and connection notifications (new followers, comments). The reason your inbox fills up is that these are often separate lists or notification types, so switching off one doesn't stop the rest.
How to stop Substack emails, step by step
- Unsubscribe from a recent email. Open a recent Substack email and use its unsubscribe link.
- Turn it off at the source. Open Substack's email or notification settings at https://substack.com/settings (substack.com/settings > Subscriptions (unsubscribe per publication); Marketing and Connections sections (turn off platform emails); Danger Zone (unsubscribe from all at once)) and turn off the categories you don't want.
Does unsubscribing from Substack actually work?
Substack email is per publication. Unsubscribing from one newsletter does not affect any other newsletter you subscribe to, and does not stop Substack's own platform emails (marketing, recommendation digests, activity digests, new-follower notifications). To fully stop Substack email you have to do both: unsubscribe from each publication individually, and separately turn off the platform emails in Settings under Marketing and Connections. The Danger Zone in Settings has a single option to unsubscribe from all publications and stop Substack emails at once. That's the part most "how to unsubscribe" guides miss, and it's why Substack email often keeps arriving after people think they've opted out.
Clear out the Substack emails already in your inbox
Unsubscribing stops new mail. It doesn't remove what's already there. On desktop Gmail, search from:substack, click the select-all checkbox, then click "Select all conversations that match this search", and hit the trash icon. Empty Trash to reclaim the storage.
If Substack is just one of many senders crowding your inbox, MailMop ranks every sender by volume so you can bulk delete and unsubscribe across all of them in one pass, in your browser. MailMop users have cleared over 2 million emails this way.
A couple of Substack-specific tips
- The footer unsubscribe link is fastest per newsletter, but after you click it a window opens and you have to choose 'Unsubscribe from all' to finish.
- Killing newsletter emails is only half the job. Use the Danger Zone 'unsubscribe from all' option (or the Marketing and Connections toggles) to also stop Substack's recommendation digests and notifications.
