01 — Persona Engine

Every mailbox gets a persistent human archetype.

At onboarding, each mailbox is assigned a persona — Fast Scanner, Avg Reader, Thorough, or Mobile-First — and keeps it for life. Open counts, dwell times, reply rates, even typo frequency all vary per persona.

Two mailboxes warming the same domain produce completely different engagement traces. That variance is deliberate — it's what real inboxes look like.

02 — Authentic Signals

Not a click. A conversation.

MailStrike personas do what real recipients do: move emails out of spam, mark them important, open across multiple sessions, click links, and reply with LLM-generated responses — including the occasional typo.

These are the behavioral signals providers reward. Not a single instant open at 9:00:01 AM every day.
