Beginning at 1:13 PM PT on June 1st, our engineering team began investigating a problem related to SendGrid Email Validations API. Our team determined that this issue began at 10:13 AM PT and lasted through 1:29 PM PT, at which point a deploy was made to fix the problem. During the affected period, the SendGrid system began producing failures for attempts made to the Email Validations API endpoint for SendGrid. Users accessing this feature would have seen "403 FORBIDDEN" API response errors despite having proper permissions and feature access to this API endpoint. This did not impact mail send. This issue has been resolved and systems are now operating normally.
