Question 1

What is DMARC?

Accepted Answer

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy that tells receiving mail servers what to do with emails that fail SPF or DKIM checks. It works alongside SPF and DKIM to prevent email spoofing.

Question 2

What DMARC policy should I use?

Accepted Answer

Start with 'p=none' to monitor your email authentication without affecting delivery. Once you've verified SPF and DKIM are working correctly, gradually move to 'p=quarantine' then 'p=reject' for maximum protection.

Question 3

Is DMARC required for cold email?

Accepted Answer

While not strictly required, DMARC is increasingly important. Gmail and Yahoo now require DMARC for bulk senders, and it can improve deliverability by 20-30% when properly configured.
