SPF Lookup Tools: The Best Free And Paid
Options For Email Authentication


The Sender Policy Framework (SPF) serves as an email authentication method designed to combat email spoofing by confirming that incoming messages come from legitimate mail servers. To verify and assess SPF records, SPF lookup tools play a key role. These tools examine the SPF records associated with a domain to confirm that the email authentication is correctly configured, thereby reducing the likelihood of phishing and spoofing incidents.
