How to Update Domain Authentication Records at Your Domain Host

This article explains how to update domain authentication records using the domain host and what to do once the records are in place.

Summary

  • Update the domain's authentication records at your domain host using the new records provided. Confirm completion so the team can finish the remaining setup.

Step‑by‑step: Update domain authentication records

  1. Obtain the new authentication records that need to be applied (these will be provided as the “new records”).
  2. Sign in to your domain host (the DNS/registrar control panel) where the domain’s DNS records are managed.
  3. Add or replace the existing authentication records with the new records exactly as provided.
  4. Save the changes in the domain host control panel.

After updating the records

  • Notify the team or the person coordinating the setup once the new records are applied so they can complete the remaining setup steps.

Important operational note

  • Do not proceed with updating or switching email configuration until the domain authentication records are updated. Emails may fail or be quarantined if the records are not in place prior to email changes.

Troubleshooting tip

  • If email delivery issues occur after attempting email updates, verify that the new authentication records were correctly applied at the domain host and that the changes were saved.

Conclusion

  • Apply the new authentication records at your domain host, confirm the changes, and notify the team so they can complete setup. Ensuring the records are updated before changing email configuration prevents delivery failures or quarantining.
