What to expect from an ideal product

1. Unlimited alias creation so every SaaS sign-up, integration, or vendor gets its own address without exposing your real inbox
2. AI-based spam classification that learns context beyond simple keyword rules, reducing false positives that block legitimate lead emails
3. SMTP relay support so outbound mail from your domain passes through the same system, keeping deliverability consistent
4. Works with your existing Gmail, Outlook, or IMAP provider—no DNS migration or mailbox switch required to get started
5. No advertising model or user profiling, which matters when your inbox contains customer contracts, investor threads, and financial data
