SEOptimer’s SPF Record Tool verifies if your domain has an SPF (Sender Policy Framework) record set up.
An SPF (Sender Policy Framework) record is a DNS record that is set to identify mail servers and domains that are allowed to send email on behalf of your domain and is designed to help combat email spoofing.
We recommend reviewing the documentation of all the delivery platforms you use to determine the appropriate SPF records to implement for your site to ensure highest deliverability.
