Reply emails aren't being sent

Last updated: 26 September 2026 · 4 min read

Steps

1. 1

   Check the error

   An email that wasn't sent has “Failed to send” and a warning icon under it. Hover over the icon to see the reason.

2. 2

   Check the connection

   Open the email channel's settings from the list in Settings › Workspace settings › Inboxes. If you see the red “Your inbox is disconnected” bar, sign in to your Google account again with the “Click here to reconnect.” link. This usually happens when the Google password changes or access is revoked. Administrators also get an email when the connection breaks.

3. 3

   Send it again

   After the connection is restored, send the email again. If the unsent message is less than 24 hours old, there's a resend button next to the warning icon.

4. 4

   Google limits

   Google limits how many emails one mailbox can send per day. If the limit is reached, sending works again the next day.
