Detecting fake contact details in typeforms

Not even an idea about how I can prevent g@gmail.com being an acceptable email? :)

@woken - may not be the best place in the process to do the validation, as there is no native Typeform way to do so - BUT you can use Zapier and integrate with one of the many email verification tools they connect with to do the validation of the email before you accept it downstream from typeform. 

i get about 20-25 dummy emails put into my example typeforms accessible here in various posts, where people put in dummy emails. I don’t filter those out cuz it’s just a sample process.. however, in live production  typeforms, that are connected to CRM/ESP solutions, I always use a zap to check the emails for validity before they are passed to the backend. 

just a thought

Thank you Des, I might have to do that. 

@woken - it might chew up the typeform submission count BUT by using the checkers, it saves me a bunch of headaches downstream in business processes if they don’t make it into the esp/crm workflows…

Hi @StoneyExplorer,

We ran into the same issue with people entering fake or incorrect emails and phone numbers in Typeform.

What worked for us was using Zapier to connect Typeform with Numverify for phone validation and ZeroBounce or Clearout for email checks. It's all no-code and pretty straightforward to set up.

Here’s how we did it:

• After a form is submitted, Zapier picks up the data

• The phone number is sent to Numverify to check if it's valid and real

• The email goes through a service like ZeroBounce to flag fake, disposable, or risky addresses

• Based on the results, we either send the contact to our CRM or mark it as invalid

This setup helped us clean up our data and avoid spending time on leads that weren’t genuine. Let me know if you want help setting it up or need more details.
