What MailMaestro is
MailMaestro is an AI email assistant for professionals, available as an extension and on the web. It drafts messages from scratch, revises and polishes drafts, corrects typos, and summarizes email threads and attachments to provide context for replies. Rapid Replies presents contextual options that users can turn into a professional response, and the assistant can write professional responses in 18 languages.
