# SHAI — Instantly

> Mailbox warm-up, sending-domain rotation, sequence builder, and deliverability/reply-tracking platform for cold outbound — distinct from Resend (transactional only).

Canonical page: /integrations/instantly

## How SHAI connects to it
SHAI talks to it directly, with the key you paste. It is one of the tools SHAI has written up — what it costs, why it matters, what breaks without it — as `instantly` in the tool guide.

## What it needs
a key you paste, in Setup or on /connections.

## Where that was read
docs/tools/tools.json (instantly), verified 2026-09-16.
