I signed up for a newsletter but am not receiving any emails. What can I do?

If you've signed up for a newsletter and haven't received your first email or you've been receiving emails and suddenly they've stopped coming, don't fret! Here are some trouble-shooting tips to help you get emails again from your favorite Substack writers.

Try testing your email address

To test whether your email delivery is working for a publication, navigate to https://publicationname.substack.com/account/email-test

You'll need to replace "publication name" with the name of the writer's Substack.

For example, if a newsletter you subscribe to is "Skyline Trails", enter the following URL:


Check your email settings

  • If you have a Gmail, check your Promotions tab. If a newsletter is in that section, move it to your Primary inbox.
  • Is the email in your Spam or Junk folder? If so, unblock sender and move to Inbox.
  • It’s also possible that your email server (especially if you're using a government, education, or corporate address) could be blocking our servers. In this case, you or your IT department will want to whitelist on@substack.com as a safe-sender in your email account. 

There may be an email block

Go to your Substack account and see if there's an "Email block" message from Substack.


Follow the instructions on how to clear the email block.
