SUBSTACK HEADERS DISAPPEAR IN THE SUBSTACK APP

Published On: July 21, 2025Categories: Email Marketing, TechnologyTags:

Be careful if you’re sending important information in the custom header or footer of your Substack newsletters. If you’re sending Zoom information or Luma invites or other special links to paid subscribers and they’re reading your newsletter in the Substack App, they won’t see it.

This is troubling, as Substack just recently said this:

We’re doubling down on the Substack app, which is designed to help audiences reclaim their attention and connect with the creators they care about.

Get everyone to subscribe to multiple publications, then users have messy inboxes. The cure? Just use the Substack App!

Then, when a publisher leaves Substack and sends a newsletter via a new service, the email will show up a users inbox again – this can be jarring!

“Wait, I thought I was getting all my newsletters in the Substack app?!?!”

So now it’s almost like people won’t be subscribed to a newsletter, they’ll be subscribed to a Substack.

This seems like a slippery slope.
