Your Outlook and Gmail in one place
Courier is an email and calendar client for Microsoft 365 and Gmail. It shows all your accounts side by side, with one combined inbox.
All your accounts
Several Outlook and Gmail accounts, one inbox for all of them.
Calendar included
Outlook and Google calendars together, and invitations answered from your inbox.
Stays on your device
Your mail is kept in your browser, not on a Courier server.
Who it's for
Courier is a personal project, built for its author and a few people they know. It isn't sold, and it doesn't show ads.
