Unbatched Events

We would like to announce a change to this new version of the Event Webhook—SendGrid will continue to post data to customers’ applications with one significant change—we will no longer be accepting unbatched events.

Adding this feature will increase the efficiency and stability of the Event Webhook. In the past, we have spent significant time recovering unbatched events that are lost while moving through the mail pipeline. This is not true of batched events as they are far more stable. As a result, we are asking developers to make this small change in order to increase performance and deliverability of their mail pipeline.

Customers who currently use batched events will experience no difference in the performance and effectiveness of the Event Webhook. However, those utilizing unbatched events will be asked to migrate to a batched format by May 1st 2014.

If you are currently using an unbatched event format, expect to receive several notifications asking you to migrate. In an effort to maintain transparency around this change please see below for our full migration schedule.
