# Alternate Email addresses

A User in Smartsheet must have a primary email address associated with their user account (User.email) and may optionally have one or more alternate email addresses associated with their account (User.alternateEmails). The following operations must be performed using an user's primary email address:

* Add Group Members
* Add User
* Create Update Request
* Share Report
* Share Sheet
* Share Workspace

Attempting to specify a user's alternate email address for any of the above operations results in an error.
