We previously announced that SparkPost will deprecate TLSv1.0 on July 9th. We have extended this date to July 23rd in order to give some customers additional time to update their injection code. Starting on July 23rd, all API calls made to SparkPost must use TLSv1.1 or higher or they will fail with an authentication error.
