 ### Streaming
 
-The SendGrid source also has a streaming component which listens in real time for inbound webhooks from SendGrid's Event Notifications and batches the events to be uploaded on your next warehouse flush. These events are only ever appended to your warehouse. Note, if you don't use SendGrid's marketing features, this will be the only data that we receive from SendGrid. At present, there is no way to retrieve email event history from SendGrid, so you will only have access to data that we've collected after you successfully enable this component of the source destination.
