Instantly only allows each email account to be connected to one workspace at a time. You'll get an "Account already exists in another workspace" error when connecting the same email account to another workspace.
It means your email account is already linked to another Instantly workspace.
Reconnecting in the Same Workspace
If you're trying to reconnect accounts in your current paid workspace, it's recommended to remove the accounts first, then add them from scratch.
Go to the Email Accounts dashboard
Find the accounts you want to reconnect
Click on three dots(...) -> Delete
Confirm removal
Wait a few minutes for the system to process
Click Add or Buy Accounts → Connect existing to connect the accounts from scratch
Adding to Another Workspace
You're trying to connect email accounts to a different Instantly workspace, but they're still linked to your old workspace.
Option 1: Move Accounts via API
Use Instantly's API to transfer accounts between workspaces programmatically.
Both workspaces must be in the same workspace group
Must use an ADMIN workspace API key

Option 2: Contact Support
We can help remove accounts from the old workspace so you can add them to your new one if you have at least one paid Instantly account/workspace.
Important: If both the source and target workspaces are on a free trial, we're unable to remove connected accounts to prevent trial abuse.
Please share the following with our support team:
List of email accounts
Old workspace ID where they're currently connected (if known)
New workspace ID where you want to connect them
Confirmation that the new workspace is on a paid plan
After removal, you can:
Go to Email Accounts → Add or Buy Accounts → Connect existing
Connect your email accounts to the new workspace
To find your Workspace IDs:
Go to the Workspace & members section
Copy the workspace ID for the admin workspace
Scroll to the Workspace Group section to locate the ID for the sub-workspaces
For an expired workspace, you can get the workspace ID on the expired page:
