An SPF (Sender Policy Framework) record is a type of Domain Name System (DNS) record that identifies which mail servers are permitted to send email on behalf of your domain. Essentially, SPF is used to prevent spammers from sending messages with forged From addresses at your domain. Implementing an SPF record for your domain can help in reducing the chances of your email being marked as spam and improves the overall deliverability of your emails.
- Configuration: SPF records are configured in the DNS settings of your domain. It specifies the mail servers authorized to send emails from your domain.
- Spam Prevention: By verifying sender IP addresses, SPF helps prevent email spoofing and phishing attacks, where attackers send emails from a forged address.
- Email Deliverability: Proper SPF setup increases the likelihood that emails sent from your domain will reach the recipients’ inboxes rather than their spam folders.
For example, a business setting up an SPF record would list all the IP addresses of their authorized email sending services in the SPF record, ensuring that emails sent from these IPs are recognized as legitimate.
