Overview

MailMaestro is an AI email assistant that integrates directly into Outlook and Gmail to draft, summarize, and manage messages without leaving the inbox. Maestro Labs, the company behind it, was founded in 2023 and launched from Singapore.

The tool drafts professional emails from short prompts and returns three variations to choose from, summarizes full threads automatically, generates context-aware reply suggestions, flags action items and deadlines, and applies smart labels across 20-plus languages. In January 2025, Maestro Labs acquired Helsinki-based Flowrite, an AI email assistant founded in 2020 as part of Flow AI, and folded its technology into MailMaestro.

MailMaestro suits professionals and sales or support teams handling high email volume who want AI help without switching tools. The free tier requires no credit card, Pro costs $12 per seat per month billed annually, and companion products include TeamsMaestro (free for 10 meeting notes per month) and Maestro Duo at $25 per month.
