Emails showing as not delivered

We are suddenly experiencing an issue with our inbox not delivering emails. Our settings have now changed; this was an abrupt disruption. The inbox is tied to a Gmail account, which is functional.

Hi @KSortland ,

Can you share a bit more about what you’re seeing? For example:

  • How are you confirming that emails aren’t arriving? Are you testing with your address, or have recipients specifically told you they didn’t get anything?
  • Are there any bounce-back or error messages, or do the emails just disappear?

Sometimes emails get blocked by spam filters. This can happen more often if HubSpot’s email tracking features are switched on, as some filters treat tracked emails more aggressively. You can try turning off HubSpot’s tracking for one-to-one emails to see if delivery improves (here’s how to do that, if needed).

If your HubSpot-connected Gmail inbox has suddenly stopped delivering emails and there are “not delivered” messages (even though regular Gmail works), here’s what to check:

Quick Troubleshooting Steps

  1. Check for HubSpot Warnings or Errors

    • Look for banners or notifications in your HubSpot Conversations Inbox or CRM.
    • HubSpot will usually display a warning if your account’s been suspended or if there’s an authentication error.
    • If you see a suspension notice, there should be an option to appeal or learn more about what triggered the block.

  2. Verify Inbox Connection & Authentication

    • Go to Settings > Inbox > Inboxes in HubSpot and check the Gmail connection status.
    • Sometimes, changes in settings or permissions can break the connection. Try disconnecting and reconnecting your Gmail account in HubSpot.

Hi @KSortland and welcome to the HubSpot Community, we are so glad to have you here!
I am sorry to hear about your experience about delivering emails. This could be related to the Google outage that happened recently?
Thanks for your help @ArisudanTiwari!
@KSortland, I wanted to check on you, are you sorted or do you still need help?
If you’d like us to look at it, could you please share more information about what exactly is happening and where?
The more info, screenshots (without sensitive/confidential information), and details you can provide, the better the Community can assist.

Thanks and have a great day!
