SiftInbox Features

SiftInbox is an AI email assistant for Gmail and Outlook that classifies, labels, and drafts replies — so you can focus on what matters.

Smart Email Classification

Every incoming email is automatically classified by priority (P1 Critical through P4 Low) and category (Sales, Customer Support, Internal, Personal, etc.). Your inbox gets labeled instantly — urgent emails rise to the top, newsletters and spam sink to the bottom.

• 4-tier priority system: P1 Critical, P2 Normal, P3 Low, P4 Informational
• 7+ default categories, fully customizable per organization
• Custom rules: "Emails from *@bigclient.com are always P1"
• Batch processing: classifies 10 emails at once for speed

AI Draft Replies

SiftInbox generates context-aware draft replies that sound like you wrote them. Drafts appear in your email's Drafts folder — review, edit, and send when ready. SiftInbox never auto-sends.

• Thread-aware: reads the full conversation before drafting
• Calendar-aware: checks your schedule before suggesting meeting times
• Uses [PLACEHOLDER] for unknown facts — never halluccinates
• Confidence scores: see which drafts are ready vs. need your input

Voice Learning

Your AI assistant learns your writing style from your sent emails. When you edit a draft before sending, it captures your corrections as training data. Your voice profile regenerates weekly to stay current.

• Bootstraps from your last 50 sent emails
• Learns from every draft correction you make
• Weekly voice profile regeneration
• Per-user — each team member gets their own voice

Enterprise-Grade Security

Security is our number one priority. Your emails are encrypted at rest with AES-256, OAuth tokens get a second encryption layer, and no data ever leaks between accounts.

• AES-256 full database encryption (SQLCipher)
• Separate Fernet encryption for OAuth tokens
• Strict tenant isolation — tested in CI
• OAuth-only authentication — we never see your email password
• Log sanitization — no email content in logs

Team Management

Invite your team, assign roles, and track usage across your organization. Each member gets their own isolated account with personalized AI settings.

• Invite via email or shareable link
• Roles: Admin, Manager, Member
• Team intelligence dashboard with activity overview
• Per-seat billing with usage tracking
