Webhook events

email.sent

Amazon SES accepted the email for delivery.

When it fires

email.sent fires once per email when Amazon SES accepts it. Acceptance is not proof of inbox delivery; wait for email.delivered. Emails the installation sends for its own account (sign-in links, invitations) never emit team webhooks.

Every email.* event for outgoing mail shares these data fields:

Field	Description
`created_at`	When the email was created.
`email_id`	The email's ID, as returned by the send API.
`message_id`	The SES message ID. Present once SES has accepted the email, so it is absent from `email.scheduled` and from an `email.failed` raised before sending.
`from`, `subject`	The stored sender and subject.
`to`	The relevant recipients. Delivery, delay, bounce and complaint events narrow this to the reported recipient; other events normally use the stored To list.
`tags`	An object of tag names to values. Empty when the email has no tags.
`broadcast_id`	Present when the email belongs to a broadcast.
`template_id`	Present when the email was sent from a template.
