5 Best Free Windows Email Programs for 2023

Ditch Outlook and access your mail with a free email client

To check your email and send messages straight from your desktop, you need an email program. Here are a few of the very best free email programs for Windows.

The email programs in this list each offer distinct features. Some apps display mail differently or have additional options for notifications or security, but they all have one thing in common: They can access email from nearly every email provider.

The offline mail programs listed below are great for accessing mail from your regular email address, but they most likely will not work with secure email providers because of the encryption they require.
