SendGrailTransactional email API

What is SendGrail? ​

SendGrail is a transactional email API. Your application calls a single endpoint to send email — receipts, password resets, notifications — and SendGrail handles delivery through AWS SES, DKIM signing, bounce and complaint tracking, and webhook fan-out.

These docs are for developers integrating SendGrail. If you can make an HTTPS request, you can send email in a few minutes.

How it works ​

Your app ──POST /v1/emails──▶ SendGrail ──▶ AWS SES ──▶ Recipient
                              │
                              └──webhook──▶ Your app   (delivered, bounced, …)

1. You send a message with a single authenticated POST request.
2. SendGrail validates it, queues it, and hands it to AWS SES for delivery.
3. As SES reports back, the message status updates and SendGrail posts a signed event to any webhook you've registered.

Before you can send ​

Sending requires two things, both set up once in the dashboard:

• A verified domain — the domain in your from address. See Domains & verification.
• An API key — the bearer token your app authenticates with. See API keys.

The Quickstart walks through both, then sends your first message.
