Email lies at the heart of our business -- customer support and customer contact is critical to our survival. This is not something that can be relegated to a Web UI or just any old client interface. Thunderbird provides small organizations (like ours) a free Email client that is full-featured, fast, and efficient. I can't imagine trying to use anything else!

The Thunderbird Email client provides a fast and easy way to corral multiple Email addresses. With support for POP3 mailboxes, you can pull your data off the Email server and retain/manage it all locally, which is great when you have to travel and may not always have access to the Email server, or for when you want the extra security of getting the data off of the Internet quickly. With IMAP support, you can enable access to a shared Email queue, allowing multiple employees to see and respond to the inbound messages -- ideal for a customer-facing "Sales" or "Support" queue -- and every user can see and search on every reply. All local messages and attachments are stored in a local profile folder, which can be easily moved to a NAS, allowing you to access the Email profile from any machine on the network. You can also synchronize your profile to your laptop so that all of your Email can travel with you into the field, even while disconnected. Add in the intuitive user interface, multiple-calendar features, a solid address book function, and you have an Email client that is hard to beat. Since it's free to use, this makes it even better!

Like with any software solution that you've used for 10+ years, the product does evolve, and they change the UI from time to time. These "improvements" may be beneficial to most users, but moving things around in the UI can slow you down, and the changes can sometimes break automation scripts that rely on specific sequences of keystrokes. Luckily, these occur only about every 2 years or so. Another issue I have is with the built-in calendar. Sometimes it captures an Event from an EMail with an ICS attachment -- and sometimes it doesn't. Apparently, Microsoft Teams doesn't send properly-formatted messages, so this is most often broken, but you can always work around it through manual data entry.

Thunderbird handles multiple email accounts. There is even a chat feature. It sorts my email. It removes the Spam and Junk correctly. It archives and stores my past emails and keeps them where they can be searched and accessed at any time. A life saver finding old emails once again!

Thunderbird is so easy to setup. Also if there is an option you want included such as a calendar or todo list or whatever, it integrates easily with add-ons and tools. There is nothing missing when it comes to this power tool!

The software has never let me down. There is nothing to say about "like least". It works. It is easy to learn. And use it every day. And have for YEARS.

Overall, Thunderbird is a feature-packed email management solution that provides advanced email features and customization options for individuals and small businesses. It is a free and open-source application that supports multiple email accounts, integrates well with other applications, and provides robust security features. However, some users may find the user interface to be complex and the performance to be slow on older computers.

Haven't found a better alternative to manage dozens of emails in one spot. Differentiates each of them in a much better way than others.

No native integration with google calendar, have to use a plugin, but still wish the calendar had a better overview.

Thanks for this innovative mailbox helping me benefit my time for more time at home. Please do keep working for this best service.

I use this simple art of sending emails attaching previous workspace references filtering how to respond to their immediate concerns. Thunderbird can classify these contact reports with much ease. This has helped many friends to get actual information with a simple inbox management.

I love adding more rules if less time can explore the most needed response. This plans how I can manage my business anywhere with this free software. This innovation always saves more cost if patches are introduced regularly for advanced users.
