Domain limits

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 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.

See 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 returns the same numbers next to the list:

{
  "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 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

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.
