Frequently Asked Questions

Common questions about this tool.

Why do my emails go to spam?
The most common cause is missing or misconfigured email authentication. Without valid SPF, DKIM, and DMARC records, receiving servers cannot verify that emails genuinely come from your domain. This tool checks all three and shows you exactly what needs to be fixed to improve inbox placement.
What DMARC policy should I use?
Start with p=none to monitor without affecting delivery, then move to p=quarantine once you confirm all legitimate senders are authenticated, and finally to p=reject for maximum protection. Always configure rua= reporting so you can see who is sending email on behalf of your domain.
What is BIMI and do I need it?
BIMI (Brand Indicators for Message Identification) displays your brand logo next to your emails in supported inboxes. It requires a DMARC policy of quarantine or reject and a Verified Mark Certificate (VMC). While optional, BIMI increases brand recognition and email open rates by making your messages visually stand out.
