Gmail Not Sending Emails in Google Workspace
Outgoing mail problems tend to fall into two categories: mail that will not send at all (stuck, error message, "sending" indefinitely) and mail that sends but never arrives or bounces. Each points to a different part of the setup.
Common Causes
- A daily sending limit being reached, which is more common for new accounts or migrated domains.
- An incorrect "Send mail as" configuration when sending from an alias.
- Missing or misconfigured SPF/DKIM records causing the receiving server to reject the message.
- A suspended or restricted user account.
- Browser extensions or a cached Gmail session causing send failures in the interface itself.
Safe Troubleshooting Steps
- Check whether the error appears immediately or after a delay - this affects whether it is a Gmail-side or delivery-side issue.
- Try sending from a different browser or device to rule out a local/browser issue.
- If sending "as" an alias, confirm the alias is correctly configured under Gmail settings.
- Check the Admin console for any sending limits or suspensions on the account.
- Review SPF and DKIM records if messages send but bounce back from certain recipients.

Frequently Asked Questions
Is there a daily limit on how many emails I can send?
Google Workspace applies sending limits designed to prevent abuse. Exact limits vary and can be more restrictive for newly created or newly migrated accounts.
Why do some recipients bounce my email but not others?
This usually points to an authentication issue (SPF/DKIM) or a reputation-based filter on the recipient's mail server, rather than a problem with Gmail itself.
