What MailMaestro is
MailMaestro is an AI email assistant for professionals who want to spend less time handling messages and improve writing and inbox organization. It drafts emails, revises and polishes existing text, corrects typos, and summarizes email threads and attachments. Those summaries can inform a generated response, while Rapid Replies presents contextual options that can be turned into a professional reply. It can write professional responses in 18 languages. For scheduling, it recognizes meeting invitations, checks availability in Outlook or Gmail calendars, and supports one-click responses. Users can share thread summaries in a Microsoft Teams channel or direct message. Magic templates and keyword shortcuts help with repeated messages and common details. The service is available as an extension and on the web. Gmail use requires Google Chrome; the Outlook version works with the web app, legacy Outlook, and new Outlook. The free plan limits Compose, Reply, and Improve to three uses per week. Maestro Labs says customer data is not used to train AI models and is encrypted at rest and in transit.
