Fillout email verification with ValidReach
Form, quiz, survey, and scheduling builder that captures respondent email addresses. Connect Fillout to ValidReach via REST API webhooks, workflow automation (n8n, Make, Zapier), or CSV/XLSX batch exports to verify email addresses before sending or syncing.
How it works with Fillout
Connect via HTTPS webhooks, automation runners (n8n, Make, Zapier), or CSV/XLSX batch exports.
- 1
Receive the form submission from Fillout on your backend or automation webhook before triggering downstream emails.
- 2
Call POST https://validreach.dev/api/v1/verify/single with your server-side API key.
- 3
Reject invalid and disposable addresses at submission time or tag the lead record before CRM sync.
- 4
Allow unknown results to proceed to confirmation so temporary mail-server timeouts never drop real leads.

Fillout email verification questions
- Does ValidReach require a native plugin inside Fillout?
- No. ValidReach connects to Fillout through standard HTTPS webhooks, our REST API (POST /api/v1/verify/single and /api/v1/verify/file), or automation runners such as n8n, Make, and Zapier—so you can inspect and control every field mapped into Fillout.
- How should I handle catch-all or unknown results in Fillout?
- Route confirmed valid addresses directly into active Fillout flows, suppress invalid and disposable addresses immediately, and tag catchall or unknown records for low-volume sending or a later retry. ValidReach never charges credits for unknown results.
- Can I verify an existing Fillout export without losing custom columns?
- Yes. Upload your Fillout CSV or .xlsx export to /dashboard/lists or POST /api/v1/verify/file, then download results with include_original=true to keep every original Fillout column alongside the verification status and reason code.
- What is the fastest way to automate Fillout verification?
- Download the workflow definition JSON on this page or connect Fillout's webhook trigger to POST https://validreach.dev/api/v1/verify/single via n8n, Make, or Zapier.
