When you are first invited to create a Message account, you will receive an email from email@example.com with a link to register. Click the link and you will be redirected to the sign up page.
Start by checking the box to confirm your email address, then enter your first and last name.
Next, enter a mobile number. The number is only used for optional once-daily text notifications that let you know how many unread messages are in your inbox. This number will never be used in communication with contacts, and will never be visible to contacts. If you're not interested in these notifications, or are unsure, you can input 555-555-5555 or another fake Messagephone number.
Create your password, and type it again to confirm. Click Create User. You will be logged in immediately - welcome to Message! You will also receive a confirmation email that your password has been created.
Whenever you want to log in to Message, simply head to app.signalvine.com.
