Keep your Typeform submissions clean and deliverable
Typeform's Email question type checks that an address is formatted correctly, but a well-formed address still isn't a real one: a typo domain, a throwaway inbox, or a long-dead mailbox all pass. Qualisend closes that gap where it matters most, at the point of capture. The live native connector verifies each new submission the moment it lands, flagging bad addresses before they reach your list or CRM, and the REST API and no-code flows do the same for any stack. For the responses you've already collected, export them once and verify the whole file in a single pass.
Connect Typeform and clean it in place
Connect Typeform and Qualisend verifies every submission at the point of capture — your past submissions in one pass, and each new one in real time as it comes in — so typos and disposable addresses never reach your lists or your CRM.
Prefer to work by hand, or verify at signup through your own stack? The CSV export → verify → reimport loop below and the REST API are fully supported too.
Connect TypeformWhat Typeform cleans for you
Typeform isn't an email sender, so it has no bounce log, suppression list, or contact-status model the way an ESP does. Its built-in hygiene is the Email question type: it enforces a valid format, requiring an @ and a domain, and rejects entries that are obviously malformed. If you switch on respondent or self-notifications, Typeform will email a receipt, but a bounce on that receipt isn't tracked, suppressed, or surfaced as a status you can act on. In practice the format check is the only gate an address passes before it lands in your results and flows onward.
What it can't catch
A format check passes anything that looks like an email, which is most of what actually hurts you. A fat-fingered gmial.com, a mailinator throwaway grabbed for a lead magnet, a role box like info@, a catch-all domain that accepts everything, and a real-looking address at a mailbox that died last year all clear Typeform's validation untouched. Nothing corrects them later either, because Typeform never sends the marketing mail that would produce a bounce, so the failure only shows up downstream in your ESP on the first campaign. Any list you assemble from responses arrives with zero deliverability signal attached, exactly like an imported list stripped of its bounce history.
Why a clean Typeform list matters
Typeform is the front door to your list, and whatever it captures flows straight into the tools that actually send. A typo or disposable caught here never becomes a bounce in your ESP, where bounces and spam complaints are what set your sender reputation. Gmail and Yahoo's 2024 bulk-sender rules make that concrete: exceed their bounce and complaint thresholds and your mail starts landing in spam or getting rejected outright. Typeform bills on responses rather than contacts, so cleaning won't change your Typeform invoice, but the payoff is real: it protects the inbox placement of every send those captured addresses feed.
Prefer CSV or the API? Here's the manual path
Forms are about capture, not cleanup: there's no list inside Typeform to scrub, so the leverage is verifying each address as it comes in, plus one export pass to check the responses you've already collected.
Export past responses from Typeform
Open your form, go to the Results tab and then Responses, and choose Download responses as a CSV. Build a filtered view first if you only want a slice to clean.
Verify the file in Qualisend
Upload the CSV to Qualisend bulk cleaning (up to 1,000,000 addresses, duplicates charged once) or paste addresses directly. The free plan's 100 credits, which never expire, cover a first sample.
Read the results
Every address returns deliverable, risky, undeliverable, or unknown with a reason code and sub-flags (catch-all, disposable, role, full mailbox), plus the MX provider and SMTP probe detail as evidence. Download the cleaned CSV.
Act on the results before they reach your list
Typeform responses are immutable, so you don't clean them in place. Import only the deliverable addresses into your ESP or CRM and hold back the undeliverable and disposable ones. You can delete an individual response from the Responses tab if you want it gone, but verifying at capture is the higher-leverage fix so bad addresses never land.
Or automate it at signup
Verify at the point of capture: connect Typeform directly through the live Qualisend connector, send new submissions to the REST API from Typeform's Connect panel via webhook, or wire a Zapier, Make, or n8n flow that checks each new response. Either way a typo or disposable is caught the instant it's submitted, before it reaches your CRM or a single send.
What Qualisend flags on every address
- Never-mailed invalid addresses, including fat-fingered typo domains like gmial.com, that would hard-bounce on your first send
- Disposable / throwaway domains grabbed to claim a lead magnet or discount
- Role addresses (info@, support@) that skew engagement-scored automations downstream
- Catch-all domains, flagged so you can segment and throttle them before the first send
- A 0–100 confidence score and machine-readable reason code for every address
The native Typeform connector is live — connect it in Qualisend under Integrations and clean your list without a single CSV. New contacts are verified automatically, and you can re-verify on a schedule.
What to do with each result
Every address comes back with a verdict and sub-flags. Here's the action that keeps your Typeform list clean without throwing away contacts you can still reach.
