## Description

Build sequences on a visual canvas that react to what people actually do: a product event, a form submission, a contact entering a list. Branch, wait, and convert, with live stats on every step.

Every email your product sends, one platform.
Four building blocks on one contact list, one set of branded templates, and one sending pipe. No glue code between tools.

Forms & lead capture
Embeddable forms with double opt-in and spam protection turn site visitors into contacts, straight into Letter.

Event-driven sequences
A visual canvas that fires on product events, form submissions, or list changes. Branch, wait, and convert.

Broadcasts & segments
One-off sends to a segment you build from traits, events, and lists, with a live audience preview before you ship.

Transactional email
Receipts, password resets, and notifications through one API call, the same templates, and the same deliverability.
