Formsite email verification with ValidReach
Online form and survey builder for registrations, orders, and lead capture. Connect Formsite 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 Formsite
Connect via HTTPS webhooks, automation runners (n8n, Make, Zapier), or CSV/XLSX batch exports.
- 1
Receive the form submission from Formsite 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.

Formsite email verification questions
- Does ValidReach require a native plugin inside Formsite?
- No. ValidReach connects to Formsite 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 Formsite.
- How should I handle catch-all or unknown results in Formsite?
- Route confirmed valid addresses directly into active Formsite 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 Formsite export without losing custom columns?
- Yes. Upload your Formsite CSV or .xlsx export to /dashboard/lists or POST /api/v1/verify/file, then download results with include_original=true to keep every original Formsite column alongside the verification status and reason code.
- What is the fastest way to automate Formsite verification?
- Download the workflow definition JSON on this page or connect Formsite's webhook trigger to POST https://validreach.dev/api/v1/verify/single via n8n, Make, or Zapier.
