Request
A request is recorded every time an application attempts to send an email through SendGrid's servers.
Whenever your application or server attempts to send an email to one of your customers via SendGrid, we will record that as a request to your SendGrid dashboard. In other words, when you send emails through SendGrid, you are essentially requesting, "Hey could you deliver this message for me?".
