# Listmint: New GTM Studio Data Enrichment Connector

> Email deliverability validation is now available as an enrichment attribute in GTM Studio's Enrich panel. Connect your Listmint account to add an additional layer of email verification to your audiences before activation — including coverage for catch-all domains — and segment on that confidence alongside your other enrichment attributes. To connect, add the Listmint connector from the GTM Studio Enrich panel using your Listmint API key.
