SPF (Sender Policy Framework) is a verification protocol that enables senders to specify which internet protocol address details are authorized to send e-mail with respect to a specific domain.
An SPF-protected domain is less popular with fraudsters and is therefore less likely to be blacklisted by spam filters. SPF additionally means that genuine e-mail from the domain is delivered.

action 3: Create your SPF record
SPF authenticates a sender’s identity by comparing the mail that is sending IP address towards the directory of authorized giving internet protocol address details posted by the transmitter in the DNS record. Here’s just how to make your SPF record:
- begin with v=spf1 (version 1) label and abide by it aided by the internet protocol address details which can be authorized to deliver mail. As an example, v=spf1 ip4:22.214.171.124 ip4:126.96.36.199
- You must add an “include” statement in your SPF record (e.g., include:thirdparty.com) to designate that third party as a legitimate sender if you use a third party to send email on behalf of the domain in question
