When to use ValidReach with Grist
Three common patterns teams deploy to stop hard bounces and protect domain reputation.
Protect Grist sender reputation
Remove hard-bouncing and deactivated mailboxes before Grist dispatches newsletters, lifecycle flows, or announcements.
Real-time signup & webhook verification
Validate new addresses at capture so typos and disposable domains never enter your Grist audience.
Scheduled list re-verification
Audit aging Grist segments before seasonal campaigns using bulk CSV/XLSX verification with full column preservation.

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