Google Workspace: what to check when Gmail does not receive emails

What should a company review if Gmail stops receiving emails?

First determine whether messages are missing from one sender, several senders or the entire domain. An administrator can review service status, the account, MX records and Email Log Search. Also check spam, routing rules, groups, blocked attachments and authentication results.

Risks to review

• Change MX records without confirming that the problem affects the entire domain.
• Create routing rules or allow lists that are too broad.
• Confuse a temporary delay with a definitive loss and request massive resends.
• Ignore signs of suspension, expired domain or compromised account.

Safe recommendations

1. Record sender, recipient, time, subject and any bounces received.
2. Check the Google Workspace status dashboard and account status.
3. Use Email Log Search to locate the message and find out its result.
4. Review MX, routing, spam, groups and rules only based on evidence found.
5. Validate SPF, DKIM and DMARC when the failure is related to authentication.
6. Test from different senders and document the scope before changing settings.

When to seek specialized help

• No users on the domain receive mail.
• MX records point to multiple suppliers or there is split delivery.
• Logs show rejection for security, authentication, or custom policies.
