How to Automate HubSpot Slack Lead Alerts?

High value leads should not wait. This setup checks for new companies in HubSpot and sends a direct Slack alert when the account looks big. Sales teams get instant notice and can start contact sooner. It is built for fast handoff and simple daily use.

A schedule runs every 5 minutes. The HubSpot node pulls recently created or updated companies using a since time that matches the polling window. Return All is enabled, so every company found in that window moves forward. A filter keeps only records with annual revenue above five million, and you can change that rule or add employee count. The Slack node posts a message to a chosen user with the company name, website, revenue, and team size. You get quick visibility without noise from small leads.

Connect HubSpot and Slack with OAuth in n8n Cloud. Keep the since value in sync with your interval, and set the filter to match your ideal customer profile. You can send alerts to a single owner or switch Slack to a channel for team visibility. Expect shorter response times, faster handoffs, and more meetings from top accounts, especially for B2B teams and agencies that watch for enterprise signals. No webhooks are needed, so setup is simple and does not depend on site access.

How do you set it up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with HubSpot and Slack. See the Tools Required section above for links to create accounts with these services.
  3. Open the HubSpot node named Get leads created last 5 minutes. In the credential dropdown, click Create new credential, then follow the on screen steps to sign in with OAuth. Give the credential a clear name.
  4. Open the Slack node named Notify sales rep. In the credential dropdown, click Create new credential, authorize your Slack workspace, and save. Choose the target user in the User field.
  5. Open the Schedule Trigger node and set the interval to every 5 minutes, or pick the interval you want for checks.
  6. Return to the HubSpot node and confirm the Since expression uses now minus the same number of minutes as your schedule. If you change the interval, update this value to match.
  7. Open the Filter node and set the condition to use properties.annualrevenue.value greater than 5000000. Adjust the number or add another rule for employees if needed. Make sure the revenue field is numeric in HubSpot.
  8. Edit the Slack message text if you want more fields, such as adding employee count. Use expressions to insert values from HubSpot.
  9. Activate the workflow. Create a test company in HubSpot with revenue above your threshold, then wait for the next run. Confirm the direct message appears in Slack.
  10. If no alert arrives, lower the revenue threshold for testing, check that the since window matches your schedule, and review the Execution log in n8n for errors.
  11. If you prefer team alerts, change the Slack node from user mode to send to a channel and select the right channel.
  12. Monitor usage and adjust the interval to respect HubSpot limits. Keep credentials current and review filter rules as your ideal customer profile evolves.
