Because HubSpot does not allow you to tag a campaign when a contact is manually entered this form should be used to enter any contacts that come from Solution Review.
This can be used for entering net new contacts into HubSpot. Contacts that already exist in HubSpot (via bulk import, manual entry, form submission, etc.) have an original source tagged that cannot be edited.
If you have questions on using this form reach out to Cobalt Iron marketing team.
