# Adding or removing domains

*Learn how to add or remove domains in your account, and how this affects your billing and domain slot usage.*

In DMARCeye, each domain you monitor uses up one domain slot, which is the main billing unit. You can easily add or remove domains from your account at any time — and we’ll adjust your billing accordingly depending on your plan.

## **Adding a domain**

Once a domain is added:

* It immediately occupies a domain slot
* If you’re on a monthly plan, it will affect your next billing cycle
* If you’re on an annual plan, you’ll be charged a pro-rated fee for the remaining billing period

## **Removing a domain**

After removal:

* The domain will no longer be monitored
* The domain slot it occupied becomes available again
* On a monthly plan, your next bill will reflect the reduced slot count
* On an annual plan, there is no refund, but the slot remains reusable

> **Important**: Even if a domain is misconfigured or not receiving data, it still counts as an occupied slot — billing is based on slots, not activity.

## **Replacing domains**

You can replace one domain with another at any time.

> Example: You remove [domain-a.com](http://domain-a.com) and add [domain-b.org](http://domain-b.org) — this counts as one slot used, not two.
