In DMARC/eye, the domain slot is the main billing unit. It defines how many domains you can monitor, and how your plan is calculated — whether you’re on a monthly or annual subscription.
A domain slot represents the capacity to monitor one domain within your account.
Each domain added to DMARC/eye occupies one slot.
The total number of slots determines your billing — not the number of reports or emails.
If you remove a domain, the slot becomes available again — and you can assign it to a new domain.
A domain slot is like a reserved seat: it’s yours for the billing period, no matter who sits in it.
Yes. You can remove one domain and add another within the same billing slot — at no extra cost — as long as you’re within your paid quota.
Example 1:
You have a Scale plan with 3 domain slots.
In week 1, you’re monitoring:
domain-a.com
domain-b.com
domain-c.com
Later, you remove domain-b.com and replace it with domain-d.net.
This is fine — you’re still using only 3 slots.
Why do we charge for slots, not “active” domains?DMARC/eye can’t reliably and automatically detect whether a domain is active or inactive in real time. The activity depends on external DNS configuration, which may change at any time — often outside our control or visibility.
That’s why we charge based on slots you’ve claimed, not whether those domains are correctly configured or receiving reports.
If you’re planning to rotate domains regularly (e.g., for testing), choose a plan with enough slots to cover your needs.
Removing a domain from your dashboard frees up a slot immediately.
On monthly billing, the number of slots used at the end of the billing cycle determines your next invoice.
On annual billing, new slots added mid-cycle are charged pro-rata.
