I like the ease of use but also the number of features and plugins available to adapt it to your specific needs. Review collected by and hosted on G2.com.

From my experience using Thunderbird it could be tricky to do some advanced stuff like exporting groups of rules into another client, eg. if I'm using two different devices. I'm also missing a server connection where rules can be executed without the client needing to be open on a PC Review collected by and hosted on G2.com.

Lightweight and reactive, can also be modified with plugins and add-ons for improved functionalities and customisation. Review collected by and hosted on G2.com.

Works perfectly for all my needs, but the function to create user does not exist yet to synchronize email on different computers. Review collected by and hosted on G2.com.

Thunderbird is free to its users. They appreciate donations. It's simple to use. Easy to put on your computer. I use it every day. Review collected by and hosted on G2.com.

Thunderbird doesn't have a special support team. Review collected by and hosted on G2.com.

I like the easy user interface of thunderbird with few clicks. Upside of this tool is we can edit the screenshots and make more alluring. Review collected by and hosted on G2.com.

I have not came across anything to dislike yet. Review collected by and hosted on G2.com.

It's free for most uses. It costs money when I want to incorporate exchange 365 through a plug-in, but it works. Review collected by and hosted on G2.com.

It can be slow at times. Not always the friendliest in use, but it's manageable. Review collected by and hosted on G2.com.

I like that the program is easy to navigate. I use it for my work email and it keeps me on track Review collected by and hosted on G2.com.

I don't really have anything that I would criticize. Updates have to happen and when they do, it takes me a minute to figure it out. Review collected by and hosted on G2.com.

The rules engine and its options that also supports IMAP - something the New Outlook for Windows no longer supports. The multiple view options for navigation folders makes categorising emails simple. The tags view is gold, especially when you have multiple email accounts and you have to remember to action several emails in the future, like paying that bill due in 3 weeks but you dont want that email left in the dreaded inbox of dispair. Their compact view for the nav folders is also fantastic.

Microsoft have moved to a simpler, less flexible Outlook product, however Mozilla seem to have kept the customisations, but they are way easier to navigate and implement than the old Outlook ever was. Bravo Mozilla! Review collected by and hosted on G2.com.

Maybe a tad resource hungry, but not a deal breaker. There's not too much to dislike about v115. Review collected by and hosted on G2.com.

I like that all of my email, calendars, and contacts are local. I can take my laptop without an internet connection and process and respond to email. Thunderbird also has a mass email addon that is terrific. Review collected by and hosted on G2.com.

The search feature is not that great. So when I need to find a specific email from a while ago I switch over to the web (gmail) to do that search. Review collected by and hosted on G2.com.

I have more than 5 email accounts business and personal. Thunderbird helps me to manage multiple email accounts.

I actively use filters to delete junk, ads and to sort and move messages between folders and use filters to highlight important messages automatically.

I also like to use quick search to find old email messages. Review collected by and hosted on G2.com.

I don't like recent user interfaces changes. It looks the quick search now is a bit laggish. Review collected by and hosted on G2.com.
