FAQ

Constant Contact email verification questions

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