Frequently Asked Questions
What DMARC policy should I use?
Start with p=none to monitor traffic without blocking emails. Once you confirm all legitimate sending sources are authenticating correctly via SPF and DKIM, move to p=quarantine, and eventually p=reject.
Is DMARC required for Gmail and Yahoo?
Yes. As of 2024, Google and Yahoo require DMARC, SPF, and DKIM for bulk senders (sending 5,000+ emails/day). Without it, your emails will bounce.
