The email address you use when you sign up for Zapier is your account email address. Zapier will send all alerts about activity on your account, and any email newsletters you’ve subscribed to, to this email address. Learn how to manage your email notifications.
Your account email address is also how Zapier verifies account ownership, so it should be kept up-to-date to ensure account access.
If you used your Google account to sign up for Zapier, you must first set a new password and disconnect your Google account before you can change your account email address.
