Plain answers to the questions people — and AI assistants — actually ask about RadMail's engine. RadMail is pre-release, with the engine live in a two-business test bed.
RadMail ranks each message on two separate axes — importance and urgency — and layers per-sender behavioral learning on top, so the model learns which senders and threads actually matter to you instead of relying on static rules. Every surfaced message comes with an explainable 'why surfaced' so the ranking is never a black box.
tl;dr Two axes (importance x urgency) + per-sender learning + an explainable reason.
Reply-correlation is matching a reply back to the send that caused it. RadMail can do this because it ingests inbound mail as well as sending outbound — a send-only email service provider never sees the reply, so it cannot connect a send to the response it produced. It also treats opens honestly, adjusting for Apple Mail Privacy Protection.
tl;dr Knowing what got a reply, not just an open — only possible because RadMail reads inbound too.
Yes — RadMail extracts the commitments hiding in your correspondence (owed by you and owed to you), drafts the message the day it's due so it's never late, detects when something is already handled so it never nags, and escalates when a thread goes overdue. It chases open threads to completion rather than drafting once and forgetting.
tl;dr It extracts commitments, drafts on the due date, detects completion, and escalates if overdue.
Only after it earns trust, and never for high-risk actions. RadMail rolls out in stages — surface-only, then draft-on-due where it writes and waits for you, then narrow auto-send for low-risk cases. Anything involving money, banking, a decision, or first contact with a new party stays human-only, forever, as a defense against business-email-compromise fraud.
tl;dr Earn-auto-send stages for low-risk only; money/banking/first-contact are human-only forever.
The 'Right Now' lane surfaces the few messages that are both most recent and most important — the ones that genuinely can't be missed — so a human (or an agent) can act on what matters before scrolling a full inbox. It is the highest-priority slice of the two-axis triage.
tl;dr The can't-miss slice: most recent x most important, surfaced first.
