If you're looking for something other than Breezemail, Inbox Zero is a good alternative. This open-source personal AI assistant, which Google endorses, is designed to help you get a handle on your inbox. It can send automated responses, remove newsletters with a single click and block cold emails, all through plain English commands. It integrates with Gmail and Google Workspace, and you can host it yourself for better data privacy.
Another option is PulseMail, which uses AI to simplify and amplify email communications. It can personalize responses, prioritize inbox emails intelligently and summarize emails in detail. PulseMail also can handle meeting requests and provide daily analytics, so it's geared for small businesses and professionals who want to keep their email work in order.
These alternatives have plenty of features to keep your inbox under control, automating some tasks and boosting productivity the way Breezemail does. They're both powerful tools to get you to inbox zero with a lot less work.
