About ValidationApp

Email list cleaning built for teams that care about deliverability.

Validation App helps marketers and agencies keep lists clean before they send. We focus on inbox checks, clear send recommendations, and straightforward pricing by volume—not surprise feature gates.

Start with a free list preview, then pick a plan for the volume and support level that fit your team—from Starter through Scale.
