How to check your DNS records

A quick way to check your CNAME, SPF, DKIM and DMARC records

Note: replace "customer.com" with your own domain.

  1. Using dig (on Mac or Linux):
    1. CNAME
      1. dig smart.customer.com
      2. This should point to whs.sendergen.com
    2. SPF
      1. dig txt customer.com
      2. This should contain "include:_spf.sendergen.com"
    3. DKIM (optional)
      1. dig txt sg._domainkey.customer.com
      2. This should contain your DKIM entry that can be retrieved from your domain settings.
    4. DMARC (optional)
      1. dig txt _dmarc.customer.com
