Tools

send(to, event, data) — you describe what happened, Sendable writes the copy and sends it. Your data values are inserted verbatim and never rewritten, so format them as they should read ("$99.00", not 99).

send_raw(to, subject, body) — exact copy you supply. For password resets and receipts where wording and links must be exact. Bypasses the unsubscribe list so a user who opted out can still get back into their account.

identify(userId, email, traits) — associate a user id with an email so you can send by id afterwards.

Test mode

A key starting sk_test_ composes normally and delivers nothing. Every result says so explicitly, so an agent can't report "email sent" when nothing left.
