EverGuard runs as an invisible helper next to Classic Outlook. Here’s exactly what happens every time a new email arrives — in six small steps.
Outlook fires an event the instant an email lands in your Inbox. EverGuard picks it up via Outlook’s standard automation API — no proxy, no server-side change, no alteration to your email account.
< 10 msEvery time you drag an email between folders, EverGuard remembers. If we’ve seen this sender before, we apply your saved rule instantly — no AI call, no cost, no delay.
instantIf the sender is new, we pass a trimmed copy of the email (subject, sender, body) to GPT-4o mini with a carefully-tuned prompt. It returns one of five categories: genuine, promotional, safe junk, dangerous, or uncertain.
typically 2–3 secondsBefore any email is moved out of your Inbox, Claude Sonnet 4.6 independently reviews it with the full message and more context. Both AIs must agree (or Sonnet is unsure) to act. If Sonnet disagrees, we leave it in your Inbox and log the save.
only when needed — adds ~3 secondsGenuine stays put. Promotional stays in your Inbox (you often want real-brand marketing). Safe junk moves to an “EverGuard Spam” folder. Dangerous moves to a “Dangerous Email” folder and triggers a gentle desktop notification.
Every decision is in the activity log. Drag an email back to the Inbox and EverGuard learns to never bother that sender again. Nothing is silently permanent — not even dangerous emails, which sit in quarantine for 30 days before they’re removed.
We built EverGuard for our own customers — so we kept this deliberately small and reversible.
