Hi Community,
Currently, HubSpot forms allow users to block submissions from free email providers using HubSpot’s predefined list, along with a manual option to add individual domains via copy-paste or by typing with comma-separated. While this works to some extent, the manual process becomes inefficient and error-prone when managing a large number of domains, making it difficult to validate and maintain accuracy.
However, it would be very helpful to have an option to upload or import a custom list of email domains.
This would allow teams to block specific domains (e.g. competitors, partners, internal domains, or known low-quality sources) and significantly improve data hygiene and lead quality across the portal.
It would be great if HubSpot could provide this option.
