Inbox Zero

Inbox Zero is a web-based AI email assistant for individuals, entrepreneurs, executives, and power users who want to automate inbox cleanup and respond faster without changing email clients.

Key capabilities include:

• AI sorting and labeling that categorizes incoming mail (including newsletters and cold email) and supports custom categories.
• Reply drafting in the user’s voice, generating pre-written responses based on email history, with optional context from calendar and connected systems.
• Bulk actions for inbox cleanup, including one-click unsubscribe and archive workflows for newsletters and low-value senders.
• Email analytics and pre-meeting briefings to identify top senders, inbox bottlenecks, and upcoming meeting context.

Pricing: Freemium with paid plans starting at $18/user/month (Starter); higher tiers include Plus ($28/user/month) and Professional ($42/user/month). All plans include a 7-day free trial with no credit card required, and refunds are available within 14 days of upgrading.

Notable for being open-source with code available on GitHub, plus a privacy-first approach and the option to self-host for teams that want more control.
