Five steps from a chaotic inbox to an AI-managed communication hub.
Connect your email
OAuth 2.0 for Gmail and Microsoft, or app-specific password for any IMAP server. Your credentials are encrypted with AES-256-GCM before storage. BumbleBox never stores your password — just a secure token.
- ✓Gmail, Outlook, Yahoo, IONOS, OVH, iCloud, any IMAP
- ✓OAuth 2.0 or app-specific password
- ✓AES-256-GCM encrypted at rest
AI scans your inbox
BumbleBox reads your history across every folder — from 12 months to 10 years depending on the plan. A 5-layer consensus engine — structural analysis, keyword rules, AI classification, sender reputation and behaviour patterns — classifies each email.
- ✓5-layer consensus classification
- ✓12 categories: needs_response, spam, newsletter, work_critical…
- ✓Runs across all IMAP folders, deduplicates cross-folder
Noise is removed
Newsletters go to the Newsletters folder. Spam to Trash. Receipts to Receipts. Notifications to Notifications. Every action is reversible with a 10-second undo toast. Only safe categories are auto-moved — needs_response, personal, and work emails never move without your permission.
- ✓Auto-move only: spam, newsletter, promotional, notification
- ✓Inbox safe: needs_response, personal, work_critical, work_routine
- ✓10-second undo on every action
You handle what matters
Your inbox now shows only the emails that call for a decision. For each one, a reply is drafted in your style — on its own in Full Auto, in one click otherwise. Read it, adjust if needed, click Send.
- ✓AI drafts generated on demand — you always review before sending
- ✓Tone-matched to your writing style
- ✓Keyboard shortcuts: j/k to navigate, r to reply, e to archive
Launch outbound from your inbox
Enter your URL — AI analyzes your business and suggests 3-5 targeted campaigns. Import prospects from 29 sources (Hunter, Apollo, LinkedIn, CSV…). AI writes personalized emails. Campaign emails go out gradually — never in a burst: you set the spacing (from about 12 seconds to 1 per hour) and the daily cap (up to 240 per day), campaign by campaign. Per-domain throttling protects your sender score. RFC 8058 headers on every send.
- ✓AI domain analysis + 3-5 campaign suggestions
- ✓29 import sources
- ✓Validation: ZeroBounce + MX + SMTP on every address
