Domain monitoring for agenciesEvery client domain. Under control.
DomainWarn monitors website, DNS, MX, SPF and DMARC of your client domains in one dashboard and tells you when something changes, before the client calls.
Checks website, SSL, DNS, MX, SPF and DMARC at once, with a score from 0 to 100. Only need one check? See the single tools

The big check
What the domain check tests
Twenty checks in one run, grouped into four areas with their own score from 0 to 100. The overall score weights the areas so one problem does not drown out everything else. Optional extras (BIMI, security.txt, CAA, IPv6, HTTP/3) only cost points when they are set up but broken.
Website
Certificate valid and matching, http and www redirect cleanly, security headers set, IPv6, HTTP/3 and security.txt in order, no trackers or Google Fonts before consent.
Mail servers reachable, SPF, DKIM and DMARC present and plausible, transport encryption enforced and reported, BIMI logo valid.
DNS
Records resolvable at the authoritative name server, DNSSEC signature chain intact, all name servers authoritative and in sync, CAA matches the certificate authority.
Domain
Registration with expiry date and hold status, website and mail IPs on no blacklist.
Or check one thing at a time
Every check of the domain check is also available as its own tool, with explanations, examples and instructions for your host.
What DomainWarn checks
Not just uptime, but the whole technical state
Journeys to checkout
Every 15 minutes a real browser adds a product to the cart and goes to checkout. If a step fails, you get an incident with the step, the error and the page text. Templates for Shopware 6, WooCommerce and login pages, test run before saving.
Change detection
Detects when MX, SPF, DMARC, DNS records or name servers change, confirms the change against a second name server and shows before and after.
Incidents instead of mail floods
Related problems become one incident, with reminders instead of constant noise. When it recovers, you get exactly one all-clear.
Daily or weekly digest
Every morning at eight or once a week: what is open, what has changed, which certificates and domains expire soon, to all channels. Critical findings still arrive immediately.
Built for agencies
Clients, domains and notes in one structure, members with roles, audit log. Maintenance windows per domain or client keep planned migrations out of the alerts.
Channels of your choice
Email, signed webhooks, Slack, Microsoft Teams, Discord, Telegram, Mattermost, PagerDuty, Opsgenie, ntfy and SMS, 20 channels in total. Minimum severity per channel, rules per domain.
Authoritative queries
DNS is checked directly at the authoritative name server, not through a resolver cache. What you see is the current state of the zone.
Missing records in one click
Create or fix DMARC, SPF, TLS-RPT and CAA straight from the finding, at Cloudflare, Hetzner, IONOS, netcup, INWX, OVHcloud, Route 53, deSEC and autoDNS. Existing records only after confirmation, nothing is ever deleted.
Visible to clients
Status page per client without login, monthly PDF report in your own design, read-only client access to their own domains.
Slack/Teams command
/domainwarn client.com shows state, certificate and open incidents right in the chat; check triggers a check, list shows the portfolio.
API, calendar, CSV
REST API with a token per organization, calendar subscription with expiry dates of domains and certificates, CSV export of the domain list for your own tools.
Extensions for WordPress, Shopware and Chrome
WordPress and Shopware report what is invisible from outside: exact versions, pending updates, the mail setup and a heartbeat of scheduled tasks. The Chrome extension checks the domain of the current page in one click.

Why not just an uptime tool?
Uptime tools see whether the site responds. DomainWarn sees what changed.
Most outages clients report are not outages: mail does not arrive because someone touched the SPF record, or the domain points nowhere after a hosting move. An uptime check is green the whole time.
An uptime tool reports
- Website does not respond
- Certificate has expired
DomainWarn also reports
- The client switched hosting yesterday, the nameservers are new
- The SPF record has been invalid since the newsletter tool changed
- DMARC is missing or set to none, mail lands in spam
- MX points to a different provider than last week
- The certificate expires in nine days, before it has expired
- The domain expires in 30 days or has been transferred
How it works
- 1
Add domains
Create clients, add or import domains. Monitors for HTTP, SSL, DNS, MX, SPF and DMARC are created automatically.
- 2
Checks run
Every few minutes DomainWarn checks each domain and stores DNS snapshots. No agents, nothing to install at the client.
- 3
Learn about changes
On changes or outages an incident is created and you get a message through your channel.
