To set up a Sender's Email, you must first set up a Sender Policy Framework (SPF) in your Domain Name Service (DNS). 

If you're having trouble setting up your Sender's Email, here's a few possible reasons: 

  • You're using a public email service provider (such as Gmail, Yahoo, etc.) - the sender's email must be tied to a domain that you own. 
  • You're setting up the record incorrectly by either attaching or leaving out the v=spf1  or ?all  at the end of your record. 
  • If you already have the above in place, you must only insert into the existing SPF record that's in place. 
  • Your SPF record should be a TXT record with the Host set to "@"
  • If you're using WIX, use your host name instead of the "@" sign.

Using DMARC? 

Larger domains typically will be using a DMARC record to add an extra layer of protection. If this is the case, DMARC validation will fail due to misalignment of your 'from' domain and the d= domain. 

A possible solution is to send emails from a subdomain (e.g., create the appropriate SPF record, and then create a more relaxed DMARC record, specifically for that subdomain.
