What it is

Newton Mail is an email app for Mac, Windows, iPhone, and Android, with a unified inbox, offline access, scheduled sending, and calendar tools. It supports Gmail, Google Workspace, Outlook, Microsoft 365, and IMAP providers, and connects with apps including Todoist, Evernote, OneNote, Trello, Asana, Claude, and other AI apps. The free plan has no time limit and supports up to two Gmail, Outlook, or IMAP accounts, 15 read receipts per month, and 20 AI actions per day. Pro costs $5 a month with annual billing and includes unlimited email accounts, read receipts, and templates, plus 200 AI actions daily. Team costs $12 a month with annual billing and a two-seat minimum; workspaces include three shared inboxes. Teams can share threads, comment, reply on behalf of others, and view activity. Newton says credentials are encrypted with AES-256-GCM and that it does not see email passwords through OAuth sign-in. Attachments are limited to 25 MB. A 14-day free trial is available.
