Manage incoming mail across service-specific email addresses by verifying that each message originates from its designated sender or domain. Unrecognized senders contacting dedicated aliases are isolated and reported, keeping your primary inboxes tidy and spotting address leaks early.

## Prompt to start with

BotBentoRecommended

```
When a message arrives on a tracked alias, look up the registered sender domain in the database. If the sender matches, route the message to the appropriate folder. If the sender is unknown or the alias is temporary and expired, draft an isolation notice and wait for user approval before bouncing or deleting any message.
