What this does

The email field maps to Airtable’s Email field type. Beyond collecting an email address, it has a full validation suite: format checking, domain blocking, typo detection, and OTP verification. Filla always validates that the value is a properly formatted email address before any other checks run. Invalid formats are rejected on both blur and submission with the message “Please enter a valid email address” — no configuration needed.

How OTP verification works

When Verify email with a one-time code is enabled:
  1. The respondent enters their email address
  2. Filla sends a 6-digit code to that address
  3. A code entry input appears on the form
  4. The respondent enters the code to verify
  5. A checkmark badge confirms verification
  6. The respondent can request a new code after a short cooldown
OTP verification adds friction. Use it on forms where you need to confirm the respondent owns the email address: event registration, account creation, or gated content access.

When to block free email providers

Use Block free email providers on B2B lead forms where you want to ensure respondents use a business email. This setting rejects any address from a list of 30+ common free providers including:
  • gmail.com, yahoo.com, hotmail.com, outlook.com
  • icloud.com, me.com, mac.com
  • And 25+ others

Common questions

Yes, and it’s a strong combination. Disposable email blocking prevents throwaway addresses; OTP verification confirms the respondent can actually receive mail at the address they provided.
No. Typo detection shows a suggestion (“Did you mean gmail.com?”) but the respondent can ignore it and submit with their original input.
They can click “Resend code” after the cooldown. Check that your inbox provider isn’t blocking Filla’s sending domain.
