Whether it's a phone number, email address or user ID, participants might enter fake or incomplete data in a required field to progress with the form quicker.
You can mitigate this by enabling our input validation features:
Email Address Validation
You can prevent the entry of disposable/temporary email addresses, personal addresses and duplicate email addresses.
You'll find all our email validation options here.
Please note: the above email address validation features are available in various paid plans, more information in the dedicated help article.
OTP Email Verification
This feature requires participants to verify their email address before proceeding. This is done by sending a one-time code (OTP) to the email address that they provided.
If getting valid emails is of importance to you then this might be a feature to consider.
Read more about it here.
Please note: OTP Email Verification is available on the Scale plan and above.
Phone Number Validation
Enhanced phone field validation can be enabled to check for the format of the phone number based on the country code selected. Additionally, the country code can be locked to a single country, and the submission of duplicate phone numbers can also be prevented.
The feature can be enabled in the Contact Form element's options, if a Phone, Mobile or Fax field is added to the form.
