How do AI email assistants work?
AI email assistants use machine learning to understand your email patterns, priorities, and communication style. They automatically categorize incoming messages by urgency, draft replies that match your voice, extract action items into task lists, and track follow-ups. The best ones learn from your behavior over time and improve their accuracy.
Are AI email assistants safe and private?
Reputable AI email assistants use encryption (TLS in transit, AES-256 at rest) and OAuth authentication so they never see your email password. alfred_ specifically uses OAuth 2.0, doesn't train AI models on your data, and stores everything with row-level security. Always check the privacy policy of any tool that accesses your email.
How much do AI email assistants cost?
AI email assistants range from free (Shortwave, Spark Mail basic) to $24.99/month (alfred_). SaneBox starts at $3.49/month for basic filtering. Superhuman is $30/month. The right price depends on what you need: simple sorting ($3 to $10/month) vs. full email automation ($25 to $45/month). Compare that to a human assistant at $5,000+/month.
