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.

What do you like best about Thunderbird?

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.

What do you dislike about Thunderbird?

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.

What do you like best about Thunderbird?

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.

What do you dislike about Thunderbird?

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.

What do you like best about Thunderbird?

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.

What do you dislike about Thunderbird?

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.

What do you like best about Thunderbird?

It was always the same experience whether I was setting up 10 accounts or 1. I recommend Thunderbird where the client hasn't already chosen some other option. Review collected by and hosted on G2.com.

What do you dislike about Thunderbird?

Too many have chosen other clients before I could pitch Thunderbird Review collected by and hosted on G2.com.
