The user interface. Its so simple & beautiful. Review collected by and hosted on G2.com.

I had disliked that there were a few features missing when I started using mailbird almost 7-8 years ago, but its great that you have got them now. Review collected by and hosted on G2.com.

Reliable integration with my work Google Mail account with additonal support for thrid-party apps like WhatsApp coupled to excellent support services. Review collected by and hosted on G2.com.

I don't find the positioning of the menus intuitive. Review collected by and hosted on G2.com.

I like the design and its ability to integrate with other apps, having them within the same app window, such as Whatsapp, Google Apps, and lots more. Review collected by and hosted on G2.com.

When resizing panels, some icons will hide, and also it does not offer inline filtering such as: by date, by the sender - instead, it offers a search filter that is fast. Review collected by and hosted on G2.com.

Integration of the calendar into the mail client Review collected by and hosted on G2.com.

Sorting and filtering needs to be improved; if the calendar could show a weekly / monthly view, would help; integration with icloud calendars should be developed and implemented ASAP Review collected by and hosted on G2.com.

It is a very good Gmail client -- fast and smooth -- and it does work very well with the various add-ons. I tried doing all of this stuff with Outlook, but it was so slow and clunky as to be useless. Mailbird does all of the email and calendar work flawlessly. Review collected by and hosted on G2.com.

The Slack integration doesn't work at all. After I sign in, I just get a blank screen. I've tried this on three different computers, and just now. I tried it after a fresh install of Windows. Tech support made one suggestion 10 days ago and have since ignored me and the problem. Also, their Chrome addon is so out of date many sites (like Slack.com) do not work. That's inexcusable.

MailBird is excellent at handling multiple email accounts, handling threads efficiently. It makes it easy to keep inboxes clean (often empty!)

It is also faster than Outlook.

Tracking (seeing who has opened an email) is excellent

Absolutely LOVE snooze (where the email is hidden until a specified time, then appears at the top of the Inbox) and delayed/scheduled sending!

Integration of commonly, but lightly, used apps is a very convenient feature.

The support function is great... if you can't find a specific answer (which happens often, given this are a young and growing app), you can get response from a human fairly easily without having to wait too long. Review collected by and hosted on G2.com.

It doesn't easily modify the dictionary, meaning that (since I use Canadian spelling with many special terms-of-the-art) I have many words flagged as mis-spelled.

The search function could be better... I often find it difficult to search for past emails which I know contain a particular word.

I wish there were an Android client (I believe it's in the works!) Review collected by and hosted on G2.com.

I met the fact that there are several options, including access to virtual drives within the software. Review collected by and hosted on G2.com.

There was a time that accessing my Google calendar was not supported. That is now resolved. Review collected by and hosted on G2.com.

Mailbird makes it easy to manage my multiple inboxes, I use it for my personal and work accounts (I have 2 work emails) and I can always easily see where mail is coming to and from. The additional apps are sometimes helpful but I usually end up just going to my web browser anyway, probably more useful on a smaller screen. Also their search is fantastic, you can query for particular items quite easily (like emails with attachments) and I am always able to find what I'm searching for, unlike other mail clients I have used.

Wish that categories from outlook could appear in mailbird as we use this feature a lot at work and would love to see it sync. Review collected by and hosted on G2.com.

The simplicity and the integration with the social media platforms. Review collected by and hosted on G2.com.

Nothing. there is nothing I can specify that I don't like. Review collected by and hosted on G2.com.
