Email clients are software applications whose primary function is to allow users to connect to an email server to send and receive emails.

Beside that, email clients offer additional features to facilitate every day email related tasks. With the use of a good email client software you can easily manage multiple email accounts, sort and categorize your email messages and contacts, use a powerful search function to search through your archived email messages, manage file attachments and set up automatic rules to filter out spam.

Below you will only find open source email clients.
