Additions and changes to the Twilio platform
As noted on 10/14/21, SendGrid has updated the system responsible for processing and logging spam report events. This change improved our system’s ability to process and count spam reports that come to us from mailbox providers when recipients mark a message as spam. Today we made additional adjustments to decode unique arguments on the spam reports coming through the Event Webhook.
This change will result in elevated spam report metrics for some Twilio SendGrid users that will level off once it catches up to all emails that have been marketed as spam. The increase in spam reports is not the result of more recipients marking more mail as spam, rather it is the result of our system capturing spam report events more completely from this date onward.
Note that this is a continuation of improvements made over the last month.
