How to track status of email in sendgrid without using SMTP.

Question

I want to send emails which contain different contents to same user and I need to track their status. Are there any way to do that without using SMTP.

Answer 1

Sounds like you want Unique Args. These are called custom_args in the v3 API mail send argument, but it's the same concept.

Once you activate the Event Webhook, all events will include the appropriate unique_args, so you can relate each specific message to each.

Also, whenever you send a message to SendGrid, the acceptange response includes a message_id, which will be in all those events.
