FAQ

Common questions

Can Knit build “Flag invalid addresses” between Bulk Email Checker and HubSpot?

Yes — describe it in the box above and Knit's Integrations Agent researches Bulk Email Checker and HubSpot's public API docs (or your own uploaded docs) and builds a working workflow, whether or not either app already has a pre-built connector.

How long does it take to build?

Minutes to a first working version, not weeks — you test it against real data before it goes anywhere near production.

Can new CRM contacts be verified automatically?

Yes. When a contact is created in HubSpot, Bulk Email Checker can verify the email and write the result back.

What happens to invalid emails?

Contacts that fail verification in Bulk Email Checker can be tagged or updated in HubSpot so they are excluded from sequences.
