Frequently Asked Questions
SPF (Sender Policy Framework) is an email authentication protocol that specifies which mail servers are authorized to send emails on behalf of your domain.
DKIM (DomainKeys Identified Mail) is an email authentication method that allows senders to attach a digital signature to emails, verifying that the email was not altered in transit.
SPF works by checking the sender's IP address against a list of authorized IPs published in the domain's DNS as a TXT record. If the IP is listed, the email passes; if not, it fails.
SPF has a limit of 10 DNS lookups. Exceeding this can cause SPF to break.
DKIM uses a private key to sign outbound email headers and a public key published in the DNS to verify the signature.
DMARC prevents unauthorized use of your domain, protects your brand reputation, and improves email deliverability.
