DomainLint

Every client domain you manage, watched.

DNS, SPF/DKIM/DMARC, blacklists, SSL and domain expiry — one flat price for all your client domains, with a branded monthly report you can give (or sell) to each client.

Try it now

Scan any domain, free.

The same checks we run continuously — SPF, DKIM, DMARC, MX, MTA-STS, SSL and domain expiry — as a one-off snapshot. No signup required.

The risk

Google, Yahoo and Microsoft now junk or reject mail without SPF, DKIM and DMARC.

Most client domains aren't compliant, and nobody is watching. Google and Yahoo started enforcing sender requirements in 2024; Microsoft's enforcement for Outlook and Hotmail began on 5 May 2025. When a client's invoices start landing in spam, the first call goes to you.

The economics

Flat price for all your client domains.

No per-domain metering, no surprise overages. Charge three clients $15/month for domain monitoring and the Pro plan pays for itself — everything after that is margin on a service you were already expected to provide.

How it works

From domain list to monthly report.

  1. 1

    Paste your client domains

    Drop in the whole list — every domain you manage, in one go. No agents, no DNS changes required to start.

  2. 2

    We check every 6 hours

    DNS records, SPF/DKIM/DMARC, MTA-STS, blacklists, SSL certificates and domain expiry — continuously, for every domain.

  3. 3

    Alerts where you work

    The moment something drifts, breaks or expires, you get an alert in Slack, Microsoft Teams or email.

  4. 4

    A monthly PDF per client

    A branded report for each client showing everything you watched and fixed. Give it away — or sell it as a monitoring line item.
