Instantly Integration

Connect Instantly to automatically enroll identified visitors into your email campaigns.

Written by John DiLoreto

Instantly is a cold email and sales engagement platform. Connecting Instantly to Knock2 lets you automatically enroll the contacts Knock2 identifies on your website into your Instantly campaigns β€” so high-intent visitors flow straight into outreach.

Instantly connects with an API key and is shared across your workspace, so you only need to connect it once for your whole team.


What you'll need

  • An Instantly account with API access

  • At least one campaign already created in Instantly

  • Admin access in Knock2 to connect a workspace integration


Step 1: Get your Instantly API key

  1. Log in to Instantly.

  2. Go to Settings β†’ Integrations and copy your API key.


Step 2: Connect Instantly in Knock2

  1. In the Knock2 dashboard, open the App Marketplace.

  2. Find Instantly in the Sequencing category and click Connect.

  3. Paste your Instantly API key and save.

Connecting Instantly won't send any data on its own β€” it only enables Instantly as a destination. To start sending contacts, add Instantly as an output in a Workflow.


Step 3: Enroll contacts with a Workflow

  1. Go to Workflows and create or edit a workflow.

  2. Choose Contacts as the source and set your filters (for example, lead score or job title).

  3. For the output, select Instantly and choose the campaign you want to enroll contacts into.

  4. Save and activate. Matching contacts will be added to your Instantly campaign automatically.
