Mozilla Thunderbird is one of the most powerful email clients, and it's completely free. Connect multiple email accounts, including those from popular email providers, your own domain or your work provider, to check in one place. Save attachments, add contact information, highlight important messages and choose traditional or threaded message view.
You're free to completely customize how Thunderbird deals with junk messages. Thunderbird also has dozens of option plugins to add features, and it can manage your calendar and to-do list. Mozilla Thunderbird can also be used as a feed reader, and you can connect your Twitter, Google Chat and IRC accounts in the native chat client.
As the years go by, email stands strong
