Common Use Cases

Teams use bulk validation to clean data across every system

Salesforce

Clean Your Salesforce Database

Export leads and contacts, bulk validate, then import clean results. Or skip the manual work entirely with our native Apex integration that validates directly inside Salesforce.

Pre-Send List Hygiene

Upload your campaign list before every send. Remove invalid, disposable, and catch-all addresses to keep bounce rates under 2%. Automate with Zapier or Make to trigger validation before every send.

CRM Migration Cleanup

Migrating between CRMs or ESPs? Validate your entire contact database before import so you start clean. Use our HubSpot or Salesforce integration to validate directly inside your CRM.
