What it does
Inbox Zero is an AI email assistant that labels emails, drafts replies in your tone, and blocks cold email. It connects to Gmail or Outlook and works from Slack, Telegram, mobile, or the web. It also offers bulk unsubscribe and email analytics.
Inbox Zero is an AI email assistant for people who want less time spent sorting and answering email. It connects to Gmail or Outlook, then labels messages into categories such as Newsletter, To Reply, and Cold Email. Replies are pre-drafted from your email history and calendar, so you can review and send. Bulk unsubscribe and email analytics help clear clutter. The code is open source, and you can self-host Inbox Zero if you want total control. The homepage states SOC 2 Type 2 certification. Paid plans start at $18 per user per month, and each plan includes a 7-day free trial. The evidence does not state whether a permanent free plan exists. Check that the AI drafts match your tone, confirm calendar and CRM connections, and review the 14-day refund terms before paying.
