An email program is required if you want to check your email and send messages straight from your desktop. This is a list of the very best free email programs for Windows.

The email programs in this list are unique from one another when it comes to features — some might display mail differently or have unique 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 due to the encryption demands they require.

eM Client is a free email program for Windows that has a very clean and updated interface, works smoothly, and is great for anyone wanting a straightforward email program.

However, there are advanced features, too. For example, you can delay emails to have them sent later, set up email rules, build distribution lists, send replies automatically, delete duplicate emails easily, empty the trash folder every time you exit eM Client, customize notification sounds, password protect the entire program, auto-backup your emails to any custom folder, download custom spell-checker dictionaries, configure custom keyboard shortcuts, set up QuickText for faster typing, translate emails, and send mail to multiple people while masking each email address from the other recipients (via the mass mail feature).

You can buy eM Client for VIP support, the ability to connect an unlimited number of email accounts, and the option to use the program in a commercial setting.

 Jon Fisher

What We Like

  • Interface is clean and minimal, yet very functional

  • Integrates with various online services

  • Includes color themes you can change

  • Pick any custom sound as a new mail notification

  • Automatically provides a free trial for Mailbird Pro

What We Don't Like

  • Isn't free for commercial use

  • Limits how many email accounts you can set up

  • Missing features found in the Pro version, like snoozing emails and quick preview for attachments

  • Takes longer to install than most email clients

  • Includes lots of ads

Mailbird offers a solid and reasonably productive email experience. Not only do you get access to your email but you can also connect to WhatsApp, Facebook, WeChat, FormSwift, Slack, Google Docs, Evernote, Dropbox, and other services.

This email program is fully functional in its Lite form, and totally free. However, if you want to remove the ads and have more features like the option to snooze emails and connect to more than just one email account at once, you have to get Mailbird Pro.

Jon Fisher

What We Like

  • Clean and modern interface

  • Rich editor for tables, pictures, freehand drawings, and more

  • Lets you access more than one email account

  • Supports a light and dark mode, and other personalization settings

  • Your email signature can include pictures and hyperlinks

  • Lots of settings you can optionally tweak

  • Includes a built-in calendar

What We Don't Like

  • Works in Windows 10 and Windows 8 only

  • Missing support for rules and filters

  • You can't make email templates

Mail is an app made by Microsoft for Windows 10 and Windows 8 that lets you sync multiple email accounts right to your desktop in a very sleek program. It even comes with a calendar app.

This email program is pretty basic, so it doesn't include advanced filtering options or rules you can set up to auto-delete messages or move emails around based on who send them. However, if you don't need all of that, then Mail is perfect for you because it's easy to set up a new email account and it integrates very well with Windows.

Jon Fisher 

What We Like

  • Setting up a new account is really easy

  • Provides a unique way to block spam

  • Includes fun animations you can use to signify when new mail arrives

  • Lets you manage multiple "identities" where you can switch between email accounts

  • You can password protect the program

What We Don't Like

  • Some features in the program only work if you have IncrediMail Plus

  • Includes ads

  • Some of the spam blocking features aren't free

IncrediMail is a fun and easy to use an email client that's unique in its animations and fun designs.

This email client includes a neat spam blocker that not only lets you block the sender's email address but also allows you to bounce the email back to the sender to make it appear as if your address isn't valid.

Unfortunately, because IncrediMail also comes as a paid version, this free one is missing things like email backup and the ability to switch between program skins.

 Jon Fisher

What We Like

  • Much cleaner UI than most email programs

  • Adding email accounts is a cinch

  • Lots of settings can be customized

  • Themes let you quickly change the entire appearance of the program

  • Lets you try out some of the Pro features for free

What We Don't Like

  • Limits how many email accounts you can add

  • Missing lots of features found only in the Pro version

Mailspring is another free email program that runs on the Windows operating system. It has a smooth and distraction-free user interface and is super easy to set up.

This program is pretty advanced, but you don't get all of the features for free. There's a pro version of Mailspring, too, which is why the free edition is limited.

With Mailspring Pro, you have support for scheduled emails, snoozing, link tracking, follow-up reminders, read receipts, and more. You can use some of these features in the basic/free edition but only a few times a week.
