The number of sending domains a workspace can add now depends on its plan:
| Plan | Sending domains |
|---|---|
| Pay as you go | 3, or 25 after your first credit purchase |
| Pro | 100 |
| Business | 1,000 |
If a lifetime license is active on the workspace, the license tier’s domain limit applies instead of the plan limit. The limit is checked when you add a domain: the Domains page shows how many domains you use, and Create a domain returns 422 when you’re at the limit. See Domain limits.
