Mocksup

When you invite a client or coworker to a private project they are sent an email with a link to that project.



If the user doesn't yet have an account with Mocksup, clicking on that link will automatically create a free account for them with the name and email address you used to invite them, log them into it and take them straight to your project.

If they do have an account with Mocksup, the email link will simply take them to the invited project.
