What are the SPF validation rules?

The receiving email server will follow the rules governed by the SPF record to determine if the email is valid. We've laid out those rules in plain language for you behind this popup!

What happens after the receiving server checks the SPF record?

Because you have a DMARC record (nice work!), the receiving server will use those settings to determine what to do with emails based on the SPF validation result, along with what type of SPF "alignment" is required.

Head over to the DMARC section to see those settings and understand how they work.
