FAQ
Clear answers to common questions about DMARC monitoring, SPF protection, and managing your email domain reputation
We analyze DMARC reports in real time to spot unauthorized senders attempting to impersonate your domain. This visibility gives you the confidence to move safely toward a p=reject policy that blocks spoofed messages before they reach recipients.
You receive an immediate alert through Slack, email, or webhook. We also provide direct links to delisting instructions along with practical technical guidance to help you restore deliverability as quickly as possible.
Yes. Our SPF auditor expands include chains, resolves mechanisms, and flags when you are approaching or exceeding the lookup limit. You also get optimization suggestions that help prevent SPF authentication failures.
In most cases, no. RUA•Watcher works at the DNS level, so you usually only need to add or update relevant records like DMARC and SPF. Once these records are in place, reports automatically flow into our system for analysis.
MTA STS helps ensure that mail transfer between servers uses TLS encryption. We monitor your policy availability and certificate validity, so you can reduce the risk of man-in-the-middle attacks and prevent silent downgrades in transport security.
