# How to invite a team member that already has an account?

Every admin in an account can [invite other team members](/en/article/team-management-and-roles-l8v842/) to join their account. As an email address can be assigned to only one account, you might get the next error when trying to invite your team team member: "The email has already been taken." In that case, the email is already used within another account.

In that case, you have 2 options:
1. In many cases, this team member has created their own trial account. Please ask your team member about this. If they don't longer need that account, he/she can delete their existing account: They should login and go to [Account settings](https://platform.adpiler.com/account) to click 'Delete your account'.
||| Deleting an account will delete all data and all team members
When your team member is no longer associated to another account, you can try to invite again.

2. Try to invite that person on another email address. You maybe can invite your team member with an email alias. When using Gmail/Google Workspace, [this trick](https://gmail.googleblog.com/2008/03/2-hidden-ways-to-get-more-from-your.html) might be helpful.
