MX (Mail Exchange) records specify which mail servers accept email for a domain. Each MX record has a priority value — lower numbers have higher priority. When sending email, servers try the lowest priority MX first, then fall back to higher values.

What is SPF and why do I need it?

SPF (Sender Policy Framework) is a DNS record that specifies which servers are authorized to send email for your domain. Without SPF, anyone can send emails pretending to be from your domain, leading to phishing attacks and poor deliverability.

DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do with emails that fail SPF or DKIM checks. Options are: none (monitor only), quarantine (send to spam), or reject (block entirely).

Why are my emails going to spam?

Common causes: missing or incorrect SPF record, no DKIM signing, no DMARC policy, the sending IP is blacklisted, email content triggers spam filters, or the domain has a poor sender reputation. Fix authentication records first.

DKIM (DomainKeys Identified Mail) adds a cryptographic signature to outgoing emails. The receiving server verifies this signature using a public key published in DNS, confirming the email was not modified in transit and truly came from your domain.

Why emails going to spam?

Missing SPF, no DKIM, no DMARC, blacklisted IP, spam-like content, or poor sender reputation.

What is DKIM?

Adds cryptographic signature to emails verified via DNS public key, confirming email authenticity.
