DMARC Records Tools
Simulate the exact impact of transitioning to a p=quarantine policy. Input your failing email volume to mathematically calculate how your pct= tag routes malicious and unauthenticated emails between the Inbox and Spam folders.
Transitioning to p=quarantine is the most delicate phase of DMARC. Enter your domain and an estimated volume of failing emails to simulate exactly how many will be delivered to the Inbox versus forced into the Spam folder based on your `pct=` tag.
Moving from `p=none` to `p=quarantine` can disrupt legitimate business emails if not done carefully. Use this tool to understand the exact mathematical impact of your DMARC rollout percentage.
pct= tag doesn't mean "reject this percentage". It means "apply the current policy to this percentage". We calculate what happens to the remainder.p=quarantine; pct=25, then 75% of failing emails (including malicious spoofs) are still delivered to the inbox. We show you this raw number.none, we highlight this massive structural vulnerability.Your feedback has been submitted successfully. We appreciate your help in improving our tools.
