Manage multiple accounts with the best email client 2026

Too Many Apps, Too Little Flow

Switching between inboxes, calendars, and tools breaks your focus. Mailbird unifies everything in one place, email, chats, tasks, and more — so you stay in flow.

Slow, Outdated, Overcomplicated

Many email clients feel clunky, clumsy, or confusing. Mailbird is lightning-fast and beautifully simple, made for users who move quickly.

Your Tools Deserve Better Integration

Disconnected apps mean broken workflows. Mailbird integrates with 30+ tools, or any custom app — so your inbox adapts to how you actually work.

I absolutely LOVE Mailbird and would not be able to function without it. The support for multiple accounts (unified or not), solid Sleep email function, the ability to display unread emails at the top, etc., etc. are unmatched by any other email client that works with the mail providers I use.
The ONE time (in 5 years!) I had to use Mailbird support, my question was answered almost instantaneously!
Fantastic product and team! Thank you!

I am very happy with Mailbird. I find it easy to use and adapt to my needs. I have had reason to contact them (mainly due to my lack of computer knowledge) and on all of these occasions I have found their promptness, understanding, instructions and follow up second to none. I would highly recommend Mailbird.

My email days go way back to the first Internet/Information/Email platform, back in the 90's! In all the years of trying to find the best email client with the most helpful and responsive moderators to resolve any questions or hiccups, I have landed with MailBird! I love tech, but don't always have the time to learn or keep up with the newest fads. I don't need to worry about that with MailBird. I was able to install, set it up with my ISP POP mail in minutes. If I can do it, anyone can! I'm not going anywhere else, I am here to stay! Thank you MailBird and team!

Mailbird is a breath of fresh air. Everything works intuitively—it's fast, clean, and fully customizable. What I love most is how smoothly it handles multiple accounts and the outstanding support that never keeps you waiting.

I have been a Mailbird customer for many years and recently upgraded to the new Mailbird 3.
That was the best decision I have made to experience the best email system.
The support given to me during the change over was first class as all my questions and requested assistance was handled with the utmost speed.
I particularly like the ongoing hints and suggestions that I receive and the one combined Mail inbox which is brilliant. It combines all my email addresses in one place,( as well as still having the individual addresses available) of which I have 5. I can update, delete, see any spam etc. all in one place saving time. There are also many other unique features making the Mailbird experience a must to have. Very highly recommended.

Mailbird is undoubtedly the best form of desktop email for Windows users.

I have been searching for a good email client on Windows for a long time and finally Mailbird Changes the game!

After trying Windows 10 Mail, I still prefer Mailbird over Mail Mailbird feels more minimalist, lightweight, and has better shortcuts. Also, Mailbird shows all mail in the same thread on the same page, which Mail doesn't.

It's smart, easy and provides businesses and professionals with one tool to check and manage emails, improve productivity, collaboration, and communication.

You Guys ROCK! Mailbird is the best thing happened to email since gmail.
