We watch the layer that can be measured.

Email deliverability advice is mostly folklore. Warm-up rituals, magic sending windows, seed-list theater — promises about an inbox nobody can actually see into.

Underneath the folklore there is a layer of hard, checkable fact: your DNS records, your authentication, your IPs, the blocklists. When that layer is broken, nothing else matters. When it decays — and it decays quietly, all the time — your email simply stops arriving, and nobody tells you.

Inbox Decay checks that layer against reality, tells you plainly whether you're good to go, hands you the exact fixes when you're not, and then keeps watching so the next silent break isn't silent.

Our own sending domain passes our own checks. We'd show you the screenshot — it's on the landing page.
