Instantly

In one line: Connect Instantly so your UnleashX agent can create and manage cold-email campaigns, add and update leads, tag campaigns, and keep your outreach moving — all in plain language.

​
1. Overview

Instantly is a cold-email outreach platform. It’s where you build sending campaigns, load and manage your leads, warm up mailboxes, and track how prospects respond across your sequences. Once connected to UnleashX, your agent can list and inspect campaigns, create new ones, update or pause existing campaigns, add and manage leads, move leads into campaigns, and tag campaigns for organization. It works against your live Instantly workspace using your API key, so it respects your account’s data and limits. Connecting Instantly to UnleashX means your outreach runs from a conversation. Instead of opening Instantly to spin up a campaign or import a lead, you tell your agent and it makes the change — cutting the manual steps while keeping your pipeline current.

​
2. What you’ll need

  • An Instantly account.
  • An API key from your Instantly settings (see Section 3).
  • An UnleashX account with access to Data Connectors.
You paste an API key. UnleashX sends it to the Instantly API as an authorization credential on every request.
Sending cold email is subject to your Instantly plan’s sending limits and your connected mailboxes’ warm-up status. Creating a campaign doesn’t override those limits — scope your sends to what your account and deliverability allow.

​
3. Get your credentials

Instantly MCP authenticates with an API key — a single secret string you generate once in your Instantly settings and paste into UnleashX. There’s no OAuth flow and nothing to install.

​
Step-by-step

1

Sign in to Instantly

Go to app.instantly.ai and sign in. If you don’t have an account yet, sign up first.
2

Open Settings

Click your profile avatar at the bottom of the left sidebar to open the account menu, then click Settings.
3

Go to the Integrations tab

At the top of Settings, open the Integrations tab. The left-hand panel there has three sections: Integrations, Webhooks, and API Keys.
4

Open API Keys

In that left-hand panel, click API Keys. Keep Version 2 selected — Version 1 is deprecated. Any keys you’ve already created are listed here.
5

Create a new API key

Click Create API Key, then fill in the form:
  • Name — a label that tells you where the key is used, for example UnleashX. It doesn’t affect what the key can do, but it matters later when you need to know which key to revoke.
  • Scopes — the permissions the key carries. Select the scopes covering campaigns, leads, and events (see the table below), or select all:all to grant full access.
Click Create.
Scopes cannot be changed after the key is created. If you pick too narrow a set, you’ll have to delete the key and create a new one. Note also that all:all grants full access to every Instantly API endpoint — convenient, but only use it if you’re comfortable with that.
6

Copy the key immediately

Instantly displays the key once. Copy it right away and paste it somewhere safe (a password manager, or straight into the UnleashX connector).If you navigate away before copying, the key is gone for good — you can’t reveal it again. In that case, just delete it from the list and create a new one.
7

Paste it into UnleashX

Head to Data Connectors → Instantly in UnleashX and paste the key (full walkthrough in Section 4). UnleashX validates it immediately, so you’ll know right away if it was copied correctly.

​
Good to know

Use a separate key per integration. A dedicated key can be revoked on its own if it leaks, without breaking every other tool that uses your Instantly account.
Your API key grants full access to your Instantly account through the API. Treat it like a password:
  • Never commit it to git, paste it in a ticket, or share it in chat.
  • Use a separate key per integration so you can revoke one without disrupting the rest.
  • If it’s ever exposed, delete it in Settings → Integrations → API Keys and create a replacement — revoking is instant.
Lost your key? There’s no way to view an existing key again. Delete the old one under Settings → Integrations → API Keys, create a new one, then reconnect the connector in UnleashX with the new value.

6. Example usage

“Create a new cold-email campaign called Q3 Outbound and add jane@acme.com as a lead.” → Runs Create Campaign to set up the campaign, then Create Lead (and Add Lead To Campaign) to load the prospect. “Mark the lead from Globex as replied and tag the Q3 Outbound campaign as ‘priority’.” → Runs Update Lead Status to set the lead to replied, then Add Tags To Campaign to tag the campaign.

​
7. Permissions & data access

UnleashX can:
  • Read and list campaigns and leads.
  • Create and update campaigns, and add tags to them.
  • Create leads, update lead status, and add leads to campaigns.
  • Delete campaigns where your account allows (this tool is clearly marked ⚠️).
UnleashX cannot:
  • Do anything your Instantly plan or account doesn’t permit.
  • Send email beyond your plan’s sending limits or your mailboxes’ warm-up status.
  • Change your Instantly account password or billing settings.
To disconnect: In UnleashX, open Data Connectors → Instantly → Disconnect. Then revoke the key in Instantly under Settings → Integrations → API Keys. Disconnecting and revoking removes access immediately.

​
9. Frequently asked questions

Does UnleashX store my leads or campaign data? No. UnleashX reads and writes your records live through the Instantly API per request; it doesn’t keep a copy of your leads or campaigns. Can the agent actually send cold email? It manages campaigns and leads. Actual sending still runs through Instantly under your plan’s limits and your mailboxes’ warm-up status. Can the agent delete a campaign? Yes — the Delete Campaign tool (marked ⚠️) makes a permanent change in Instantly. Use it deliberately. Where do I find my API key again? You can’t view an existing key. Delete the old one in Settings → Integrations → API Keys, create a new one, and reconnect.
