About SendGrid

SendGrid provides email delivery tools that applications can use through an API or SMTP. Set up a test sender, authenticate the sending domain and confirm one representative message arrives before routing real traffic. Delivery events can help explain what happened after an application submits a message, especially if the recipient does not see it. Keep application credentials out of client code and handle sending errors predictably. Check current plan limits and any features needed for sender separation or templates. Verify event processing and test messages in several mail clients when moving a working receipt or account email flow.
