SummaryEmailmetry handles changes to your providers’ sending servers automatically. When you add or remove a provider, update your sending services in Emailmetry and test your mail.

What updates automatically?
Your provider changes its sending servers. Emailmetry follows updates to the supported provider records you use, checks the new addresses and updates SPF automatically. Your Emailmetry DNS record stays in place.
You add or remove a provider. Update the sending services for your domain in Emailmetry. This tells Emailmetry which providers you want to authorise. Follow the new provider’s setup instructions for DKIM and any other required DNS records.
Before adding a service
- Check the sending domain. Find the provider’s envelope-sender or return-path domain, used for bounced mail. It may be your main domain, a subdomain or the provider’s own domain.
- Read the setup instructions. Use the SPF and DKIM values supplied for your account.
- Save the current settings. Keep the DNS names, values and TTLs, along with the list of services already sending mail.
- Add the provider in Emailmetry. Keep any existing services that still send mail selected. Follow any additional DNS instructions for the new provider.
Use one SPF record at each DNS name. Adding another v=spf1 record for the new service creates an error. Microsoft’s SPF configuration guidance.
Checklist and service list
Keep your current settings, proposed changes and test results together.
After the change
Check the published DNS records and send a test email from the new service. Test existing services too: for example, your mailbox, an invoice and a website notification. Inspect the SPF, DKIM and DMARC results on the received messages.
DNS answers are cached for a period set by the record’s TTL (time to live), so changes may not appear everywhere at once. Allow for this when checking a new record or restoring an old one. Cloudflare’s explanation of TTL.
Make sure you can restore the previous DNS values and provider selection if a change causes problems. Compare the current records and test results with what you saved. Restoring a record also takes time to reach servers with cached answers.
Before removing a service
Check that it has stopped sending. Look for scheduled campaigns, queued messages, website integrations and occasional jobs such as monthly statements. Allow for legitimate messages still in transit before removing its authorisation.
Remove the service from your domain’s selected providers in Emailmetry once it is no longer needed. Record when you removed it so anyone else managing the domain can see what changed.
Keep your service list current
Record each service’s name, purpose, account administrator and sending domain. Update the list when you add or retire a tool. Emailmetry handles changes to your chosen providers’ sending addresses automatically.
Removing a domain from Emailmetry frees its licence for another domain. You keep the purchased licence, so removing the domain does not cancel it or reduce the bill. Read licences and billing, including cancelling through the portal.
