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