@gmail and @msn and other freemail addresses could be high-level prospects in disguise. Blocking specific domains rather than blocking all freemail will ensure you’re getting forms from valid contacts.

How to block specific domains from submitting forms:

1. Go to the email section of the form or pop-up form (Figure 2)
2. Enter the spam domain name – the @ not needed (gmail.com not @gmail.com)
3. Publish the form (if a HubSpot page)
4. Update the form (if it is not a HubSpot page)

The offending spammer will see this notification (Figure 3) and will not be able to submit the form.
