How domains are counted

A counted unit is one separately managed hostname.

1. client.example and mail.client.example are two domains.
2. client.example and client.example.net are two domains.
3. The DNS records and DKIM selectors a domain's email policy needs count as part of that domain.
4. Removing a domain frees its slot at once; nothing is deleted from your history.

The free plan holds 1 domain and every Business plan holds up to 20. An MSP or Enterprise agreement sets its own domain allowance, and counts each client domain once. Prices come from the published catalog shown on /pricing; the same catalog is used by checkout and by agents. See Pricing.
