Why publishers choose ValidReach
Verification that protects the newsletter
Audience email is a core product surface. Treat verification as infrastructure — not a one-off cleanup before a big send.
Protect newsletter reputation
Stop undeliverable addresses at subscribe so daily and weekly sends stay out of bounce trouble.
Cleaner acquisition
Catch typos and disposable inboxes on paywall and newsletter forms before they pad vanity metrics.
Healthier engagement reporting
Opens and clicks mean more when the list is not full of dead mailboxes.
Clear risk flags
Flag disposable, role, free, and accept-all so growth can route risk deliberately.
One result language
Dashboard, bulk lists, and the API share deliverable / risky / undeliverable / unknown.
Fair prepaid credits
Unknown checks never consume credits. Packs scale with list size and campaign cadence.
Real-time API
Capture a valid email at subscribe
Gate newsletter and registration forms so typos and disposable inboxes never pad the file.
- Gate subscribe and registration — Verify before the address hits your ESP or identity system.
- Same model as list jobs — API responses match bulk hygiene — newsroom growth and lifecycle stay aligned.
- Wire every capture point — Homepage, article CTAs, apps, and events can share one verification call.
- Fair when unclear — Unknown outcomes never burn credits, so edge cases stay cheap to re-check.
