Set Up Sender Domain Authentication (Custom DNS Records: DKIM, SPF, DMARC)

Email Authentications (DKIM, SPF, DMARC) can only be added to domains you or your business ownership and control. To authenticate your domain, you'll need to copy and paste information from MailExpress into your domain's records. Depending on your domain provider or management software, the steps and information you need to create your records may vary. If you do not know where your domain is managed, reach out to the person or team that manages your website or email address for help.

Here are some instructions for editing DNS records with popular domain providers.

If your service isn't listed here, log in to your provider's site and search their help documents, or contact their customer support team.
