The SaaS deliverability challenge
Fake and disposable signups
Throwaway and mistyped emails inflate your metrics, waste resources and never convert.
Onboarding email in spam
Sending welcome and verification mail to bad addresses raises bounces and hurts inbox placement.
Distorted funnel data
Invalid signups skew activation and conversion numbers, making product decisions harder.
