Why netMail as an Outlook alternative?

The email client for Windows, Linux and Apple Silicon focuses on what a desktop client really needs to do well: respond quickly, keep large mailboxes manageable and render complex HTML emails legibly.

Appointments, contacts, tasks and notes are located directly alongside your messages and accounts.
