ZapBounce and Typeform
Typeform's one-question-at-a-time flow creates an opportunity most forms do not have. The respondent is still there after the email question, working through the rest.
That means a verification result can reach them before they finish, which no single-page form can offer.
Format validation lets a dead domain through
Typeform checks that an email answer looks like an address. It accepts anyone@thisdomaindoesnotexist.example without complaint, because the string is well formed.
For event registrations and lead-magnet forms, which is much of what Typeform is used for, that address then receives nothing and the respondent assumes you did not follow up.
Typeform's respondent notifications go to the same address, so a bad one means the respondent never gets their confirmation either.
How the data moves
Use the webhook for the verification call
Typeform fires a webhook on completion with the full response payload including the address.
Use logic jump for an in-form correction
A hidden field updated by your handler can drive a logic jump back to the email question. That is the flow-specific trick worth building.
Write the verdict with the response
Wherever the responses land, the verdict belongs beside them so nobody has to re-check later.
Verify partial submissions too
Typeform can fire on partial responses. An address captured before abandonment is still a lead worth checking.
Setting it up
- Register a webhook on the Typeform for response submission.
- Verify the address in your handler with the key held server-side.
- Write the verdict into your CRM or sheet alongside the response.
- For in-form correction, use a hidden field and a logic jump back to the email question.
- Handle partial responses too, since an abandoned form still captured an address.
- Verify the webhook signature before trusting the payload.
Typeform: common questions
Does Typeform verify email answers?
It checks the format. Whether a mailbox exists is a different question and Typeform does not ask it.
Can I correct a typo inside the form?
With a hidden field and a logic jump, yes. Typeform's one-question flow is unusually well suited to it.
Should I verify partial responses?
Yes, where you capture them. An abandoned form still gave you an address worth knowing about.
