In order to enhance security for all of our users, Twilio SendGrid now requires customers on all Essentials plans to use API Key authentication on all API requests and SMTP configurations. Customers must also enable Two-Factor Authentication (2FA) for all users, including teammates. Visit our docs for more information on Upgrading to API Keys and Enabling Two-Factor Authentication. If you did not receive notifications about this change please update your account email address.
