Your email is greyed out on the profile page. Everything else there you can edit; that one you have to ask us about.
Why
Your email address is your identity on swipesign. It's how you sign in, it's what your verified identity is attached to, and it's recorded in the audit trail of every document you've ever signed or sent.
If it could be changed from inside the account, then anyone who got into your account for five minutes could take it over permanently: change the address, reset the password to the new one, and lock you out. Making the change go through us removes that path.
It also keeps old audit trails honest. A signature from two years ago should still point at the address that actually signed.
What to do instead
Contact support from the address currently on the account and tell us the new one. Documents you have already signed keep the old address in their audit trail, which is intentional.
