How to set up DMARC for Send13 in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for Send13 and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your Send13 emails


You will have 4 settings in a DKIM record for Send13.

Record type: TXT

TTL: Select the default.

Hostname: send13._domainkey.yourdomain (yourdomain being the actual domain you are editing DNS for)

Hostname, Name, Host; same thing different names. And a number of hosting specific entries.

  1. Click add new DNS record

  2. Select type TXT
