How To Configure SPF SPF, DKIM & DMARC on Bluehost

1. SPF Check & SPF Lookup
2. Newsletters spam test by

SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are two important email authentication methods that help prevent email fraud, spam, and phishing attacks.

  • SPF is used to verify that the sender of an email message is authorized to send email from the domain that appears in the sender’s email address.
  • DKIM is used to verify that the content of an email message has not been tampered with during transmission.

By using SPF and DKIM together, email recipients can be more confident that the email messages they receive are legitimate.
