The problem

Fire a send on any event, done right

Your best emails are the timely ones, but wiring events to sends usually means glue code, a queue, and a brittle integration you have to babysit.

The old way
  • Every event-driven email is a custom script, a queue, and a template that drifts off-brand.
  • Order confirmations are plain-text afterthoughts from a different system.
With Mailable
  • Webhook in, on-brand email out. No glue code, no babysitting.
  • A purchase event triggers a branded receipt in seconds.
01

Triggers for any event

Signup, purchase, inactivity, a schedule, or a custom event, all can fire a send.

  • Event, time, and behavior triggers
  • Per-recipient personalization
  • Start a campaign or a sequence
