What to expect from an ideal product

1. Supports unlimited alias creation so you can assign a unique address to every site, service, or contact without managing separate accounts
2. Forwards alias mail to your existing inbox without requiring you to migrate away from Gmail, Outlook, iCloud, or any IMAP provider
3. Applies spam scoring, virus scanning, and AI classification before delivery, not just keyword filters that senders can bypass

5. Operates without advertising, data selling, or user profiling, which matters when the entire point is protecting your address from third-party exposure
