Verify every Jotform submission before it lands
Jotform validates that an email field is well-formed, but a well-formed address can still be a typo, a disposable domain, or a dead mailbox — and a form has no send-and-bounce loop to ever catch that. Qualisend closes the gap: the native Jotform connector verifies each new submission in real time at the point of capture, and you can bulk-verify everything you've already collected with a single CSV export. When you'd rather build it yourself, the REST API and Zapier/Make/n8n flows check the address the instant a submission fires.
Connect Jotform and clean it in place
Connect Jotform 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 JotformWhat Jotform cleans for you
Jotform is a capture tool, not a sender, so its built-in hygiene is thin by design. On an email field you get format validation, an optional unique-email rule to block duplicate submissions, and an autoresponder confirmation you can require — but all of that checks shape, not deliverability. Jotform keeps no suppression list and retires no addresses, because it never runs the campaigns that would produce a bounce. Its notification and autoresponder emails can bounce silently, and nothing in Jotform learns from it.
What it can't catch
That means a well-formed but undeliverable address sails straight through: typo domains, disposable throwaways, role inboxes like info@ and support@, decayed mailboxes, and catch-all domains all pass format validation and land in your submission table looking perfectly healthy. Unlike an email platform, Jotform can't even be reactive here — there is no send, so there is no bounce to fire and no status to flip. Whatever your CRM or ESP inherits from the form arrives with zero deliverability signal attached. Submissions imported or migrated from another tool are the sharpest case: they carry no bounce history at all, so addresses that were already failing look brand new.
Why a clean Jotform list matters
Jotform bills on monthly submissions and form volume, not on contacts, so a bad address costs you nothing on the Jotform invoice — the whole cost is downstream. Every unverified submission you pass to your ESP or CRM drags the sender reputation of the domain that eventually mails it. Gmail and Yahoo's 2024 bulk-sender rules judge that domain on bounce rate and hold you under a 0.3% spam-complaint threshold, and a lead form is the single most common on-ramp for the typos and disposable addresses that blow past both. Verifying at the form is the cheapest place in the whole funnel to stop them.
Prefer CSV or the API? Here's the manual path
A Jotform form is a capture point, not a list you clean — so the highest-value move is verifying each address the moment it's submitted, with a one-pass CSV clean for everything you've already collected.
Export past submissions from Jotform
Open your form's Submissions table (or Jotform Tables), click Download All, and choose CSV or Excel. You'll get one row per submission with the email in its own column — Reports → Excel/CSV produces the same file.
Verify the file in Qualisend
Upload the CSV to Qualisend bulk cleaning — up to 1,000,000 addresses per job, duplicates charged once, with live progress. The free plan's 100 credits that 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 and a 0–100 confidence score. Download the cleaned CSV.
Route the results downstream
Submissions are immutable, so you act on the results, not the form: import only the deliverable addresses into your CRM or ESP, tag or move the risky rows to a separate tab in Jotform Tables for reference, and leave undeliverables out of every send.
Or automate it at signup
Point a Jotform webhook (Settings → Integrations → Webhooks, available even on the free plan) at the Qualisend REST API so every submission is verified the instant it fires — before the address reaches your CRM. If you'd rather not write code, a Zapier, Make, or n8n flow does the same thing and lets you branch on the verdict to route deliverable leads one way and quarantine the rest.
What Qualisend flags on every address
- Well-formed but never-mailed addresses that would hard-bounce the first time your ESP sends to them
- Disposable and throwaway domains built to expire minutes after the form is submitted
- Role addresses like info@ and support@ that skew every engagement-judged automation downstream
- Catch-all domains, flagged so you can route and throttle them instead of trusting them blind
- A 0–100 confidence score and machine-readable reason code, with the MX provider and SMTP probe as evidence, on every address
The native Jotform 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 Jotform list clean without throwing away contacts you can still reach.
