BounceProtect
Clean your email lists before you send
Generate a valid DMARC record for your domain.
Configure your DMARC policy and generate a ready-to-publish DNS TXT record. Choose your policy level, coverage percentage, and reporting email.
DMARC policy
Start at 10% and increase gradually. Use 100% once you are confident in your setup.
DMARC rollout strategy
Start with p=none and pct=100 to collect reports without affecting email flow. Review the reports for two to four weeks. Once you see that legitimate email passes authentication, move to p=quarantine at 10%, gradually increasing to 100%. Finally move to p=reject for full protection. Rushing to reject without monitoring first can block legitimate email.

Frequently asked
Always start with p=none. This lets you collect reports without affecting email delivery. Review the reports for 2-4 weeks, fix any authentication gaps, then move to p=quarantine at a low pct, gradually increasing to p=reject.
