Twilio Verify now supports email verification, allowing developers to send and validate email addresses with a single API call. The process involves setting up a Twilio account, Sendgrid account, and creating an email template using HTML code. A Twilio Verify service and email integration are then created, and a Node.js script is written to authenticate with the Twilio Client and send verification emails. The script also includes a route to check the verification code provided by the user, which uses the Twilio library to verify the code against the one sent in the email. This functionality can be integrated into a sign-up experience using a mock database and redirecting users to a verify page once they receive their verification email.
