Verified reviewer Pharmaceuticals 51-200 employees Used daily for more than 2 years Review source Reviewed October 2023 Thunderbird, the GO-TO Lightweight mailing client 5 We started using Thunderbird as an alternative for our outlook clients, performing even better during the days, and making it a go-to software for our new installations. Ratings Breakdown 5 Ease of use 4 Functionality Pros: I think the most impactful thing about Thunderbird is the community that uses the software, making it evolve constantly and performing better. It is awesomely easy to set up and makes yourself feel really at ease, with a simple UI and plugin enhancements that make it even better. Cons: I think Cloud support could be more extensive, to make Thunderbird evolve to the next level, the team should really make it an objective inside the application. Reasons for switching to Thunderbird We made the switch because of the problems and security issues, we resolved them with plugins + firewalls, features that could be only be accomplished with Thunderbird.

Verified reviewer Transportation/ Trucking/ Railroad Self-Employed Used daily for more than 2 years Review source Reviewed November 2024 Thunderbird for Email 5 I like the ability to use and even build plug ins and add ons to enhance the experience. Ratings Breakdown 4 Ease of use 5 Value for money 5 Functionality Pros: I like that it is open source and works on many different platforms. Cons: Sometimes it will take a long time to synchronize using IMAP if the folders get big. Reasons for choosing Thunderbird I sometimes had to use Linux systems, so Thunderbird made most sense.

Verified reviewer Hospitality 201-500 employees Used daily for less than 6 months Review source Reviewed August 2024 Not worth the time 3 It was pretty much a complete disappointment. With the calendar and the mail and then it using 50% CPU. Ratings Breakdown 3 Ease of use 1 Value for money 1 Customer support 1 Functionality Pros: We didn't not like it. We started looking for alternatives within a few weeks Cons: It kept deleting our calendar. And since we are a hotel our calendar is very important. It also just stopped fetching mail. Reasons for choosing Thunderbird We thought it was a better deal. We were very wrong Read More JV Jose Miguel V. Verified reviewer Education Management 1001-5000 employees Used daily for less than 2 years Review source Reviewed June 2023 A proof that free can be good 4 Since I have been using Thunderbird, I never regret my switch from Outlook. Over the years, although the development has not been fast, it has been fast enough for the product to adapt, at least in functionality, to what every mail client must deliver to its user.If you are looking for a robust free email client, Thunderbird is the best option. Ratings Breakdown 4 Ease of use 5 Value for money 4 Functionality Pros: I am sure that many people like me came to this product because it is the Mozilla Foundation behind it. We all know how they think about their product, making privacy their flagship. In the case of Thunderbird, you can find a robust email client with functionalities at the level of many other paid clients. If I need to list Thunderbird's advantages, I will start by talking about its extensibility, making it one of the first email clients you can improve and customize with free third-party add-ons. Another great addition of the last years was the "Smart folders," making your multiple account inbox easier to visit and search.Right now I am using Thunderbird for all my personal emails, and the client has all you need to manage successfully all your personal data flow.Thunderbird is free, and for sure is the best option for email clients at this tier. Cons: I will list the things I think can be improved in Thunderbird, but I repeat, we are in front of a robust FREE client, so please consider this when you read about the following points.Complexity: While Thunderbird's extensibility is a strength, it can also be a weakness. The sheer number of options and settings can be overwhelming for less tech-savvy users, and it may take some time to configure it to your liking. This one was my first problem after I switch from Microsoft Outlook.Aesthetics and UI: For me, this is a big problem. While this is subjective, and the interface can be customized, when you open Thunderbird you are looking at a user interface that has not been modernized according to the times.No Native Mobile Application: On June 22, Thunderbird announce the partnership with K-9 email to make real the Android native mobile application, until now, this not happens. Almost all people manage their emails on the go from their smartphones, so again, this is a must for a modern email client. Reasons for switching to Thunderbird I tried their email solution because I love what Mozilla Foundation makes with Firefox. Read More WP Wiktor P. Verified reviewer Education Management 2-10 employees Used daily for less than 2 years Review source Reviewed June 2023 Thunderbird needs more integration with other software 4 It is good inbox managment software for the smaller companies or solo enterprenuers, but when you need to optimize some processess in your organization, it may lack integration abilities. Ratings Breakdown 4 Ease of use 5 Value for money 3 Customer support 4 Functionality Pros: It is fast, easy to use and the search function is excellent. You can easily find conversation without knowing its exact topic, content or receiver, thunderbird can find it even wtih some general keywords. Cons: Lack of integration with another softwares that controls workflow. It is just separate software without connection to other processess in my organization. I would like to see it integrated with some note taking apps, communictaion softwares like Slack, Calendars, projects managment software etc. Reasons for choosing Thunderbird faster, better design, better search option and inbox managment, better price (free) Reasons for switching to Thunderbird faster, better design, better search option and inbox managment.

Verified reviewer Entertainment 11-50 employees Used daily for more than 2 years Review source Reviewed October 2022 Thunderbird is the ONLY email software you need. 5 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! Ratings Breakdown 5 Ease of use 5 Value for money 5 Customer support 5 Functionality Pros: 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! Cons: 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. Reasons for switching to Thunderbird The programs I was using before, would not load on some days. They didn't have all the features that I could setup and wanted. Thunderbird has it all. Loved it from the first day I set it up. Read More GS Grant S.
