Kit (ConvertKit) email verification questions
- Does ValidReach require a native plugin inside Kit (ConvertKit)?
- No. ValidReach connects to Kit (ConvertKit) 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 Kit (ConvertKit).
- How should I handle catch-all or unknown results in Kit (ConvertKit)?
- Route confirmed valid addresses directly into active Kit (ConvertKit) 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 Kit (ConvertKit) export without losing custom columns?
- Yes. Upload your Kit (ConvertKit) CSV or .xlsx export to /dashboard/lists or POST /api/v1/verify/file, then download results with include_original=true to keep every original Kit (ConvertKit) column alongside the verification status and reason code.
- What is the fastest way to automate Kit (ConvertKit) verification?
