How do I start a Chat thread?

To start a new thread, tap the Chat icon on the bottom row of the Substack iOS app. If you have Chat enabled, you'll see a row for your publication. Tap that row and then select "Start a New Thread". Subscribers cannot start a new thread.


Note: Each chat thread that you start can include text, links, and up to six images.


Type a message you'd like to share with your subscribers. 

  • To add an image: Tap on the picture icon to select photos from your device.
  • To share a link: Long-press within the thread body to paste a link. If the link you're sharing has a preview, it will appear.
  • Choose your audience: If you'd like only paid subscribers to access this thread, tap on the lock icon and tap "Paid subscribers".


Once you've finished composing a message, click on the up arrow and your thread will appear in the Chat.


How are subscribers notified about Chat?

When you post your first chat, we'll notify your subscribers via email. Your subscribers won't be emailed about any following chat threads but if they have notifications enabled on the Substack iOS app, they'll receive a push notification about any new threads.
