A new Google Workspace domain needs verified ownership, Gmail activation, and correct public MX records before internet mail reliably reaches its users. A working Google sign-in alone does not establish incoming-mail delivery.
Confirm the intended mail-hosting design
Before editing DNS, identify the domain’s current mail provider and any planned gateway, split delivery, or migration arrangement. Save the existing records and the approved cutover plan. Changing MX affects incoming mail for the domain, not just one user’s screen.
Verify the domain or subdomain in Workspace and confirm that the intended users have Gmail access. Keep domain registration, DNS hosting, and mailbox licensing separate in your diagnosis.
Check the published MX records
Google’s current standard setup uses the MX destination smtp.google.com with priority 1. Enter it using the DNS provider’s required host-name and trailing-dot format. Follow the plan for any existing mail gateway rather than blindly replacing a deliberate configuration.
Older Google Workspace domains may use the legacy aspmx records. Google explicitly says those remain supported and need no change when mail is working. Do not replace a valid legacy set merely because a newer guide shows one record.
Activate Gmail and test external receipt
In the Admin console, an authorized administrator can use Account, Domains, Manage domains and Activate Gmail for the relevant domain. Check the records visible on the public internet using the supported diagnostic tools.
Google allows up to 72 hours for new MX records to be recognized. During a cutover, retain old-service access and monitor delivery according to the migration plan. Test from an external sender, keep any bounce, and use message logs to distinguish DNS routing from an invalid recipient. Do not change SPF, DKIM, or DMARC at random to repair an inbound MX problem; those mechanisms serve different authentication purposes.
