Webhooks

Webhooks in the Voxtelesys Email API let your application stay in sync with real-time email events. Instead of polling for updates, your server receives HTTP callbacks as soon as something happens—like a successful delivery, a link click, or an unsubscribe. This event-driven approach makes it easy to automate actions, streamline workflows, and build responsive email experiences.

For a general overview of how webhooks work, refer to the Webhooks Overview.

Email Webhooks​

For the Email API, webhooks are triggered in the following scenarios:

  • Delivered: A webhook is sent when an email is successfully delivered to the recipient.
  • Send Failed: A webhook is sent when an email fails to send or deliver.
  • Opened: A webhook is sent when a recipient opens the email.
  • Clicked: A webhook is sent when a recipient clicks a tracked link in the email.
  • Complained: A webhook is sent when a recipient marks the email as spam.
  • Unsubscribed: A webhook is sent when a recipient unsubscribes.
