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