When to use ValidReach with Linked API
Three common patterns teams deploy to stop hard bounces and protect domain reputation.
Pre-enrollment gate for Linked API
Verify enriched B2B lists before uploading to Linked API so invalid mailboxes never burn sending quota or trigger provider blocks.
Catch-all & role-account isolation
Separate catch-all corporate domains and role aliases (info@, sales@) from confirmed valid mailboxes before launching cold campaigns in Linked API.
Automated enrichment pipeline check
Insert ValidReach between your lead source and Linked API via n8n, Make, or Zapier so only verified prospects enter active sequences.

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