DMARCER offers two licence types so you can protect both the domains you send email from and the ones you do not. Picking the right type for each domain means every domain you own is defended against spoofing, not just the ones you use day to day.
Standard
A standard domain is one you actively send email from. DMARCER monitors and scores all of its email-security checks (SPF, DKIM, DMARC, DNSSEC, MTA-STS and deliverability), collects and analyses the DMARC reports that receivers send back, and guides you step by step through tightening your policy all the way to a full enforced reject. Choose Standard for any domain that sends mail to your staff, customers or suppliers.
Parked
A parked domain is one you do not send email from but still want to protect. DMARCER locks it down with an enforced DMARC reject policy and an SPF record that allows no senders at all, so receivers reject anything claiming to come from it. You get this protection without needing the full sending setup that a Standard domain requires.
Parked is not just unused domains
Parked does not only mean a domain you have finished with. It also covers the domains you hold for brand protection: common misspellings of your name, alternative endings (.co, .net, .org, .io), country variants, and names you registered defensively so that nobody else could. Those are exactly the domains an attacker would love to send from, so they belong in DMARCER too.
Why owning the domain is not enough
It is a common and costly assumption that simply buying a domain keeps it safe. Sadly, it does not. A domain with no DMARC, SPF or DKIM records is wide open: someone can send email that claims to be from it, and because nothing tells receivers to reject unauthenticated mail, those messages can land in inboxes looking exactly as though they came from you. Registering a domain stops someone else owning it, but on its own it does nothing to stop someone spoofing it.
Adding every domain you own to DMARCER, whether Standard or Parked, closes that gap. Parked protection takes only a few minutes per domain and turns a silent liability into a domain that actively rejects anyone trying to impersonate you.
