How to Validate email from a master list and throw error while submitting form

[Sri1]

Hello
I have a form which accepts email from user. If the entered email is not in master list of emails, then form should highlight this to user and should not proceed with submitting form.
Please suggest if there are any direct / workarounds

Thanks

Airtable forms can’t prevent somebody from submitting a form based on whether their email is in a master list.

I would take a look at JotForm for that functionality. Check out the support article below:
