# Domain limits

> How many sending domains each Emailit plan and AppSumo license includes, what happens when you reach the limit and how to raise it.

Each workspace can add a set number of sending domains, based on its plan or license. This page lists the limits, explains what you see when you reach one and how to get more room.

## Domains per plan

| | Pay as you go | Pro | Business | Custom |
| --- | --- | --- | --- | --- |
| Sending domains | 3 (25 after your first credit purchase) | 100 | 1,000 | By agreement |

- **Pay as you go** starts at 3 domains. After your first credit purchase in the workspace, the limit rises to 25 and stays there.
- **Pro** and **Business** have fixed limits of 100 and 1,000 domains.
- **Custom** plans include the number of domains in your agreement.

Every domain counts toward the limit, whether it's verified or not, including each subdomain you add separately.

## AppSumo licenses

When an AppSumo license is active in a workspace, its domain allowance replaces the plan's.

| AppSumo tier | Sending domains |
| --- | --- |
| Tier 1 | 1 |
| Tier 2 | 2 |
| Tiers 3 to 6 | Unlimited |

See [AppSumo](/docs/billing/appsumo/) for everything else a license includes.

## See your usage

In **Email API → Domains**, a badge next to the page title shows domains used and the limit, for example `2/3`. Hover over it to see which plan sets the limit, such as "Pay as you go plan allows up to 3 domains." Workspaces with an unlimited license don't show a badge.

With the API, [List domains](/docs/api-reference/domains/list/) returns the same numbers next to the list:

```json
{
  "data": [],
  "next_page_url": null,
  "previous_page_url": null,
  "domain_limit": 3,
  "domain_count": 2,
  "plan_name": "Pay as you go"
}
```

`domain_limit` is `null` when the workspace has no limit. `plan_name` is `License` when an AppSumo license sets the limit.

## When you reach the limit

- **Dashboard:** the **Add domain** button is disabled.
- **API:** [Create a domain](/docs/api-reference/domains/create/) returns `422` with a message that names the limit:

```json
{ "error": "Pay as you go includes 3 domain(s)." }
```

  With an AppSumo license, the message is `This license includes 1 domain(s).`

Domains you already have keep working. The limit only stops new domains from being added.

## Raise your limit

| Current plan | How to get more domains |
| --- | --- |
| Pay as you go | Buy credits once in **Workspace → Billing** to go from 3 to 25 domains, or upgrade to Pro. |
| Pro | Upgrade to Business for 1,000 domains. |
| Business | [Contact sales](/contact/) about a Custom plan. |
| AppSumo tier 1 or 2 | Upgrade your license tier on AppSumo. Tiers 3 and higher are unlimited. |

You can also free a slot by deleting a domain you no longer use. Only workspace admins can delete domains, and deleting one drops any messages from it that are still being sent.
