How to connect Google Vertex AI and Lemlist
Create a New Scenario to Connect Google Vertex AI and Lemlist
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a Google Vertex AI, triggered by another scenario, or executed manually (for testing purposes). In most cases, Google Vertex AI or Lemlist will be your first step. To do this, click "Choose an app," find Google Vertex AI or Lemlist, and select the appropriate trigger to start the scenario.

Add the Google Vertex AI Node
Select the Google Vertex AI node from the app selection panel on the right.

Save and Activate the Scenario
After configuring Google Vertex AI, Lemlist, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Google Vertex AI and Lemlist integration works as expected. Depending on your setup, data should flow between Google Vertex AI and Lemlist (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Google Vertex AI and Lemlist
Lemlist + Google Vertex AI + Google Sheets: When a new activity occurs in Lemlist (e.g., an email reply), Vertex AI analyzes the sentiment of the reply. The sentiment score and the reply text are then logged in a Google Sheet for tracking and analysis.
Lemlist + Google Vertex AI + Slack: When a new activity is detected in Lemlist, specifically a negative email reply, Vertex AI summarizes the feedback. This summary is then sent to a dedicated Slack channel to alert the team for immediate follow-up.
