Groundhogg CRM Mailing Address Verification Automation

This workflow implements automatic verification of contact mailing addresses to ensure their accuracy and validity. By calling a third-party address verification service, the system automatically determines whether the address is deliverable and assigns appropriate tags to the contacts. The verification results are updated in the CRM, supporting subsequent manual review or customer confirmation. This significantly reduces mailing failures due to incorrect addresses, improves business efficiency, and enhances customer experience, making it suitable for businesses and teams that require precise mailing.

Key Features and Highlights

This workflow automatically receives and verifies mailing addresses of new contacts added to Groundhogg CRM, determining whether the addresses are deliverable. By integrating with a third-party address verification service (Lob API), it ensures the accuracy and validity of addresses.
