email validation feature - entering a fake or free email address

Question

Hi,I need your help with something: We want an email validation feature that is preventing the lead from entering a fake or free email address (e.g. Gmail, Yahoo, etc.) in Marketo forms.I couldn’t find yet any external provider who can do it in real-time, only after (e.g EmailHippo, Kickbox). If you can’t do both, is there an option only for this case: if I will enter in the Marketo form the following email: guyalgo@gmail.com, there will be an error message, asking me to enter company email only?I’ve seen a post of someone who wrote a Validation script to prevent from Bots filling in forms (the form will not submit). I wonder if we create a validation script for case if the email address contains specific keywords (e.g. test, gmail, yahoo, etc.)?Best,Guy

Why do you want to stop people from downloading your content? Some people only use gmail/yahoo/outlook, so instead of letting them learn about you or get your trial, you are causing friction and will most likely cause them to abandon the process. What is more important: clean email addresses or leads looking to learn about and possibly buy your product?

If you must do this, you will need to write some custom Javascript:

Forms 2.0 JS API Documentation: http://developers.marketo.com/rest-api/assets/forms/examples/
Search for "RegEx free email accounts"
Write a function that fails validation if the email address matches the regex test.

P.S. Bots don't respect JavaScript, so any validation written to deter them will most likely not work.
