What email verification does

Email verification (OTP) requires respondents to confirm they own the email address they entered by receiving and entering a 6-digit code. The form cannot be submitted until the code is verified. This is configured on the Email field, not at the form level.

​
When to use it

  • Event registrations where you need to confirm the attendee can receive emails
  • Account creation forms where a valid, owned email is required
  • Gated content access where you need to confirm identity
  • Any form where you want to prevent fake or borrowed email addresses

​

What verification confirms

OTP verification confirms that the respondent has access to the inbox. It does not verify that:
  • The email address exists at the domain level
  • The domain has valid MX records
  • The address can receive all types of email

Common questions

They can click “Resend code” after the 30-second cooldown. Ask them to check their spam folder. The code comes from Filla’s sending domain.
Yes. The provider block runs first. If the email is from a blocked domain, the respondent sees an error before they can even request a verification code.
The verification status is not stored as a separate field. The verified email address is stored in the email field as normal. The form will not submit without the verification being completed.
Yes, it adds an extra step. Use it only when confirming email ownership is worth the added friction for your use case.
