Kast and Instantly: contacts who know you

Instantly is built for volume and deliverability. The problem with volume is list quality. Kast gives you a steady flow of contacts who have engaged with your content, which moves your reply rate more reliably than any warmup setting.

What the integration does

01

Transfer without a file

From the Leads screen, contacts go into the Instantly campaign of your choice. Kast reports batch by batch: how many were accepted, how many were duplicates, how many had no valid email.

02

A single threshold, set at 70

Only leads whose ICP score reaches 70 are offered for transfer. This threshold is the same for every account and can't be changed: it's a product constant, not a setting.

03

What goes out, and what stays

Instantly receives the identity: email, first name, last name, company, job title. The original comment and the source post aren't sent; they're in the CSV export, not in the transfer.

How to connect it

1

Paste your Instantly API key

Settings › Platforms, one key per Kast account. Kast never falls back on a key shared between customers.

2

Choose the campaign when you transfer

Kast reads your list of campaigns in Instantly. One campaign per send, chosen by you: there's no automatic routing by score.

3

Watch the reply rate

It tells you whether the leads you sent deserved a sequence. Since the threshold is fixed, the tuning happens in your campaign, not in Kast.

Frequently asked questions

No. Kast doesn't replace Instantly, it feeds it. Sending, warmup and inbox rotation stay on their side.
It depends entirely on your engagement volume. An account with a few hundred reactions a month produces a few dozen qualified contacts, not thousands.
