Version 1.9.0 · Windows 10 and 11 · free for 15 days, no card neededEverything is in every plan. No add-ons, no ads, nothing sold to anyone.
Gmail, Microsoft 365, Outlook.com and any IMAP mail, side by side or in one combined inbox. Unlimited accounts.
Your replies and their answers in one thread, with quoted text folded away.
Flag for today, tomorrow or next week, mark important, and get reminded to reply later.
Priorities, summaries and a reply ready under each email, with a free AI that runs on your own PC, or Claude if you prefer.
Outlook-style rules sort mail as it arrives; out-of-office and after-hours replies use your office hours.
Mail is stored on your PC, passwords in Windows' own credential store, and a PIN can lock the app or single emails.
Try everything free for 15 days. Then pick the license that fits. Prices in US dollars, per year.
"Users at a time" is how many people can have MailClient open at once. Install it on as many of your licensed PCs as you like; a place frees up as soon as someone closes it.
No account to create and nothing to cancel by phone.
