What it is

MailMaestro is an AI email assistant for drafting, revising, and organizing professional email. It writes messages from scratch, polishes drafts, fixes typos, and summarizes email threads and attachments; those summaries can inform generated responses. Rapid Replies offers contextual response options that users can turn into a professional reply, and the assistant can create professional responses in 18 languages. It detects meeting invitations, checks availability in Microsoft Outlook or Gmail calendars, and enables one-click responses. Users can share thread summaries in Microsoft Teams channels or direct messages. Magic templates and keyword shortcuts help with repetitive messages and commonly inserted details. MailMaestro is available as an extension and on the web. Its Gmail version is a Chrome extension and works only in Google Chrome; its Outlook version works with Outlook web, legacy Outlook, and new Outlook. The free plan limits Compose, Reply, and Improve to three uses per week. The Professional/Team plan is $15 a month per seat, and MaestroDuo is $27 a month per seat. Maestro Labs says customer data is not used to train AI models and is encrypted at rest and in transit.
