Hey n8n community! 
I’ve just built a workflow designed to solve a major headache for anyone managing a CRM: Data Decay. As contacts sit in HubSpot, their emails can become invalid or risky over time, leading to bounces that hurt your deliverability and inflate your Marketing Hub costs.
This Hygiene Loop template automates the entire audit process using NeverBounce.
What it does:
-
Scheduled Audit: Automatically pulls contacts from HubSpot on a daily or weekly schedule.
-
NeverBounce Verification: Checks every email status in real-time.
-
Automatic Cleanup: If an email is flagged as “invalid” or “risky,” n8n instantly updates the Lead Status in HubSpot to ‘Disqualified’.
-
Team Reporting: Sends a summary report to your Slack channel so you can see exactly how many records were cleaned up.
See it in action (60s Demo):
The Workflow Logic:
-
Trigger: Schedule (Daily)
-
Data Source: HubSpot (Get Many Contacts)
-
Verification: NeverBounce API
-
Action: HubSpot (Update Lead Status)
-
Notification: Slack (Audit Report)
How to use it:
-
Import the JSON below.
-
Connect your HubSpot and NeverBounce credentials.
-
Adjust the “Check if Risky” logic to match your specific internal property mapping.
I’d love to hear how the community is managing CRM hygiene! If you have any questions or ideas on how to expand this logic (like adding a 're-opt-in' email for risky but not invalid leads), let’s chat in the comments. 🚀
