Twilio SendGrid Suppressions API

The Twilio SendGrid Suppressions API allows you to manage your Suppressions or Unsubscribes and Suppression or Unsubscribe groups. With SendGrid, an unsubscribe is the action an email recipient takes when they opt-out of receiving your messages. A suppression is the action you take as a sender to filter or suppress an unsubscribed address from your email send. From the perspective of the recipient, your suppression is the result of their unsubscribe.
