To change the email address on your account, which is also your login name for your account, first log into your Formstack account. Then click on My Account > My Profile at the top right of the screen, and you can change your email address on that page.
Please note: If you see options in this screenshot that are not in your account it could be because of your user permissions or account type. If you have any additional questions about those specific options, please feel free to reach out to email@example.com.
