Substack accidentally sent duplicate emails for some of its newsletters

Substack had a problem today that caused some of the platform's newsletters to be sent out for a second time. Several of us have seen additional copies of some of the emails we subscribe to in our inboxes after the Verge sent out a second copy of the free edition for his Platformer newsletter.

Substack co-founder Hamish McKenzie told The Verge that it was a one-off bug.

Looks like Substack just re-sent this week’s free @platformer post to you all. Not sure what happened — also getting lots of notifications for older posts from other Substacks.

It's not clear how many emails were duplicated, but the company said in a statement that a recent update triggered duplicate emails for a subset of writers. We apologize for the delay to you and your readers. We will make sure it doesn't happen again.

If you missed the last edition of The Kicks You Wear, getting a second copy is more of a reminder than an annoyance. The still-in-beta RSS reader or mobile app can be used if you're not happy with the way you receive a newsletter or receive too many.
