Watch an IP or domain

Free alerts when a watched IP is listed or delisted on a public blacklist, or when a domain's SPF, DMARC, DKIM or MX record changes. We only email about changes, after you confirm the address. Unsubscribe any time.

What to watch

For an IP this starts as blacklist only. For a domain it starts as DNS and blacklist. Change either box.

Privacy

We store the email address and the IP or domain only so we can send these alerts. We don't sell addresses. Nothing is emailed until you confirm, and every message has an unsubscribe link. How this works.

Questions

What will you email me about?

For an IP, a listing or a delisting on a public blacklist. For a domain, a change to the SPF, DMARC, DKIM or MX records, and a blacklist listing or delisting if you leave that box ticked. We do not write when nothing has changed.

Do you email me straight away?

First we send a confirmation. Alerts start only after you open that link. If the address cannot receive mail, you simply will not get the confirmation. We do not tell the form whether the inbox exists.

How do I stop?

The link in a confirmation or alert opens a page listing what that address is watching. Remove one, or remove them all, from there. You can watch up to 10 addresses.
