Keep every Gravity Forms submission deliverable
Gravity Forms captures leads, registrations, and contact requests straight into your WordPress entries table, then routes them to your CRM or ESP. But it only checks that an email is shaped correctly, so typos, disposable domains, and dead mailboxes sail through and bounce on your first send. Qualisend closes that gap with a native Gravity Forms connector and a REST API that verify each address at the point of capture, before a bad one ever reaches your lists.
Connect Gravity Forms and clean it in place
Connect Gravity Forms 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 Gravity FormsWhat Gravity Forms cleans for you
Gravity Forms validates the email field for correct syntax on submit and can require confirmation, so a field left blank or missing an @ is rejected at the form. Its anti-spam layer (the honeypot, plus reCAPTCHA or Turnstile) and the Spam and Trash entry statuses in Forms, Entries help you quarantine junk submissions after the fact. Because Gravity Forms is a form builder and not a sender, it has no bounce processing or suppression list of its own. Its hygiene ends at format and spam, not at whether the mailbox actually exists.
What it can't catch
Syntax validation happily accepts user@gmial.com, a disposable mailinator.com address, or a role inbox like info@ because all three are perfectly well-formed. Gravity Forms cannot see that a mailbox is full, decayed, or sitting on a catch-all domain that accepts everything and delivers nothing. It is also reactive by nature: nothing flags a bad address until you export it, mail it, and watch it hard-bounce in your ESP. Addresses imported into Gravity Forms or pushed downstream arrive with any prior bounce history stripped, so a mailbox that already failed elsewhere looks brand new here.
Why a clean Gravity Forms list matters
Gravity Forms is a flat WordPress license, but every unverified address it captures flows into a CRM or ESP that bills per contact, so junk submissions inflate your seat count directly. Worse, they hit your sender reputation: a form is the front door, and one typo or throwaway address bounces on every downstream send. Since February 2024, Gmail and Yahoo hold bulk senders to a spam-complaint rate under 0.3% and low bounce rates, and a form that keeps feeding invalids into your sends is the fastest way to trip those thresholds and land in spam.
Prefer CSV or the API? Here's the manual path
Forms are about clean capture, not cleanup: the win is verifying each submission the moment it arrives, so a bad address never reaches your lists in the first place.
Export your entries to CSV
In WordPress admin go to Forms, Import/Export, Export Entries. Pick the form, include the Email field with any date range or conditional filters, then click Download Export File.
Verify the file in Qualisend
Upload the CSV to a Qualisend bulk job. It handles up to 1,000,000 addresses per run, charges duplicates only once, shows live progress, and your first 100 credits are free and never expire.
Read the verdicts
Every row comes back deliverable, risky, undeliverable, or unknown, with sub-flags for catch-all, disposable, role, and full mailbox, the MX provider, the SMTP probe as evidence, and a 0 to 100 confidence score and reason code.
Act on the flagged entries
Back in Forms, Entries, bulk-select the undeliverable rows and move them to Trash or Mark as Spam so they stop syncing, and stop the matching addresses from flowing into your CRM or ESP sends.
Or automate it at signup
Skip the export loop entirely by verifying at the point of capture: fire a Gravity Forms webhook or a Zapier, Make, or n8n step on each new submission that calls the Qualisend REST API, so typos and disposable addresses are caught before the entry ever reaches your CRM. Scoped keys, rate limits, and result webhooks let you branch the flow on the verdict returned.
What Qualisend flags on every address
- Never-mailed invalids that would hard-bounce on your next send, like gmial.com typos or long-dead mailboxes captured through the form
- Disposable and throwaway domains such as mailinator.com or temp-mail.org used to grab a lead magnet without giving a real inbox
- Role addresses like info@, support@, and sales@ that land in shared inboxes and drag down engagement and reply rates
- Catch-all domains flagged so you can segment or throttle them instead of trusting an accept-all server that may still bounce later
- A 0 to 100 confidence score plus a machine-readable reason code on every address, with the SMTP probe kept as evidence
The native Gravity Forms 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 Gravity Forms list clean without throwing away contacts you can still reach.
