Hello Jaycee,
Sorry for the delayed response, I was out of office. I did consider doing myself via the JS route, but that would be very time consuming, since I’d have to rebuild all of our forms from scratch. Currently, our forms do all the work under the hood, in terms of sending emails to the user that submitted the form, allowing them to download eBooks and whatnot, and it would be a lot of trouble. I know that for many technologies, users are able to suggest new features to be added, so perhaps that could be something that Hubspot could consider? If I just had the option to add a message if the email contains “gmail.com” (or if the email is from a free email provider) that would be very helpful. At the moment, I only have the option to show another input field.
Thank you, Ford
