- Go to Lists > Employees > Employees.
- Click Edit next to the name of the employee for whom you want to set up access.
- Under Email|Phone|Address, enter the employee’s email address. The email address is required for login.
- Click the Access tab.
- Check the Give Access box.
- Check the Send New Access Notification Email box to inform the user how to access your NetSuite account. The standard user access notification includes the email address to use for logging in to NetSuite. It also contains a URL so that the user can set up a NetSuite password. The user must set up a NetSuite password within 24 hours or the URL will expire.

Sometimes the mail will be sent to only the currently logged-in user. So need to change the ‘ email options’ in the Email preferences( Set-Up > Company > Email Preferences).
In the “Sent Email To” box give the email address of the employee of whom you want to set up access.

Click Save.
