Growform email verification with ValidReach
Multi-step lead generation form builder designed for high-converting landing pages. Connect Growform 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 Growform
Connect via HTTPS webhooks, automation runners (n8n, Make, Zapier), or CSV/XLSX batch exports.
- 1
Receive the form submission from Growform 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.

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