If you want to invite your team members but the system says they are already invited first and foremost check if they received the email from us. Maybe the email with the confirmation link got stuck in spam.
If no email is found, you can invite your team member again by adding +1 after his name like this: firstname.lastname@example.org. Note that this trick works only on the Gmail domain. Also, it is not possible to register several Revealbot accounts under one email.
If the trick above doesn't work, please contact us and we'll try to sort it out quickly 👌
