How can I change the email address for my account?
Twilio will occasionally send important notifications and system messages to the email address associated with your account, so it’s important to keep this email address up to date.
You can change the email address, username or password associated with your account on the Settings page.
Please note that your username and contact email are the same. If you change your email address to “email@example.com”, the next time anyone logs in to Twilio they will need to use “firstname.lastname@example.org” as your username, so be sure to inform your colleagues that you made this change if you are sharing a login.
