You’ve got accounts with missing or incorrect MX records. You can use a tool like MX Toolbox to check them. If they’re wrong, ask your email provider to fix them. Invalid MX records can cause warmup issues and stop you from receiving replies.
MX values for Microsoft can be found in Settings → Domains → Pick Domain → DNS records.
MX values for Google can be found in their setup guide in admin console/instructions.
Update MX at your DNS host and save it. Then wait for DNS to propagate.
Keep only the MX set required by your current provider. Remove legacy entries.
Don’t mix a gateway’s MX and your provider’s MX unless that’s the intended flow.
Re-check MX any time you migrate providers or change DNS.
If you’re managing many inboxes, monitor warmup removals: spikes often correlate with MX misconfigs.
Share your domain and a screenshot of your DNS MX rows with support (mask other records if needed).
Tell us your provider (Google/Microsoft/other). We’ll validate your MX
