Set up email records

There are two reasons to set up email records for your domain: to make sure email reaches your mail server and to prevent other email senders from spoofing your domain.

​​ Add MX records

To route emails to your mail server, you need to create two DNS records within Cloudflare:

  1. An A or AAAA record for your mail subdomain that points to the IP address of your mail server.

    TypeNameIPv4 addressProxy status
  2. An MX record that points to that subdomain.

    TypeNameMail serverTTL

​​ Prevent domain spoofing

There are several DNS mechanisms to prevent others from sending emails on behalf of your domain. These all work as TXT records that need to be added on your domain:

​​ Configure email security records

To set up email security records:

  1. Log in to the Cloudflare dashboard and select your domain.
  2. Go to DNS.
  3. For Email Security, click Configure.
    • If your domain sends email, use the available options to set up SPF, DKIM, and DMARC records.
    • If your domain does not send email, use the Your domain is not used to send email section to set up restrictive email records.
