6 Best Email Clients For Windows – Free Outlook Mail Alternatives

Home » Freeware and Software Reviews

For those using Microsoft Windows 10, the build in Outlook Mail is pretty decent. Compared to Apple’s iOS Mail, Outlook Mail for Windows 10 lacks a simple feature where all emails are displayed all together. It makes perfect sense since I do not receive many emails and owns 5 email accounts, thus a central email folder makes perfect sense.

1. Thunderbird


Software made to make email easier. Thunderbird is a free email application that’s easy to set up and customize – and it’s loaded with great features! It supports POP (storing mail locally on your hard drive so that it can be accessed without an internet connection), and IMAP. It features excellent mail filter capabilities and management. Thunderbird makes email better for you, bringing together speed, privacy and the latest technologies. Works great on Microsoft Windows 10.

  • Phishing Protection – Thunderbird protects you from email scams which try to trick users into handing over personal and confidential information by indicating when a message is a potential phishing attempt. As a second line of defense, Thunderbird warns you when you click on a link which appears to be taking you to a different Website than the one indicated by the URL in the message.
  • Cutting Out the Junk – Thunderbird’s popular junk mail tools have been updated to stay ahead of spam. Each email you receive passes through Thunderbird’s leading-edge junk mail filters. Each time you mark messages as spam, Thunderbird “learns” and improves its filtering so you can spend more time reading the mail that matters. Thunderbird can also use your mail provider’s spam filters to keep junk mail out of your inbox.
  • Robust Privacy and Do Not Track – Thunderbird offers support for user privacy and remote image protection. To ensure a user’s privacy, Thunderbird automatically blocks remote images in email messages.

    It would be nice if you also spoke to the calendar function. Outlook webmail is terrible. You “categorize” by color but on the printout, you can barely see the ultra-thin color bar versus color-filling the entire cell with color.
