Frequently asked questions
How do I monitor SPF, DKIM, and DMARC records for a domain?
Paste the URL of a page that displays the domain's DNS or email authentication records. The AI watches SPF, DKIM, DMARC, MX, and NS entries and alerts you when any of them change. It calls out risky shifts, such as an SPF change from -all to +all, a new sending host, or a loosened DMARC policy.
How quickly will I be alerted to a record change?
Choose instant alerts to be notified as soon as a change is detected, which is important because a silent SPF or DMARC edit can enable spoofing right away. If you prefer, a daily or weekly digest groups all record changes into one report so you can review email authentication drift on a set schedule.
Do I need special access to the domain to monitor it?
No. As long as the records are shown on a public lookup page you can open in a browser, you can paste that URL and start monitoring. You do not need to own the domain or hold DNS credentials, which makes it useful for watching partners, vendors, or your own domains from the outside.
