Automate High-Value Lead Alerts with HubSpot and Slack in n8n

What This Workflow Does

This workflow checks HubSpot every 5 minutes to find new leads created in that time.

It filters those leads to keep only companies with more than $5 million in annual revenue.

Then it sends a detailed message about the lead directly to the right sales rep on Slack.

This saves salespeople from manually searching leads and ensures they quickly follow up on the most valuable opportunities.

Who Should Use This Workflow

Any sales team using HubSpot to track leads who want to focus on high-value companies.

It helps sales managers and reps avoid wasting time on less promising leads.

Teams that work daily in Slack will find notifications convenient for fast action.

Beginner Step-by-Step: How to Use This Workflow in n8n

Importing and Setup

1. Download the workflow using the Download button on this page.


2. Open your n8n editor, then use "Import from File" to add the workflow.


3. Add your HubSpot OAuth2 credentials under the HubSpot node to allow data fetching.


4. Add your Slack OAuth2 token under the Slack node for sending messages.


5. Check the Slack node and update the recipient field with the correct sales rep user ID or channel ID if needed.


6. Verify the Schedule Trigger timing matches the HubSpot node 'since' parameter (default is 5 minutes).

Testing

7. Manually run the workflow to test if leads are fetched and messages are sent.


8. Fix any error messages related to credentials or missing data.

Activation

9. Once testing passes, activate the workflow using the toggle button.


10. Monitor successful runs in the executions panel.

If hosting n8n yourself, it's helpful to review self-host n8n options for performance and control.

Customization Ideas

• Change the Filter node to select leads based on number of employees instead of revenue.


• Send Slack messages to a channel for team-wide notifications instead of single users.


• Modify the polling interval in Schedule Trigger and the HubSpot node 'since' parameter (e.g., every 10 minutes).


• Add a Code node to run custom JavaScript on leads for scoring or formatting before messaging.


• Include more lead details like deal amount or lifecycle stage in Slack messages.

Common Problems and Solutions

• No leads returned from HubSpot node: Usually the 'since' parameter does not match the polling time. Try increasing the timeframe or aligning intervals.


• Slack message not sending: Check Slack user ID or OAuth2 token validity. Reauthenticate and verify user IDs with Slack API tools.


• Filter node excludes all leads: Confirm property names exist and use toInt() for number comparisons. Adjust filter logic if properties differ.
