Mailbird Next is here: one email app for Windows and Mac

What Mailbird Next is

Mailbird Next is one desktop email client for Windows and Mac, built on a single codebase. The same app and the same account setup work on both, so switching computers doesn't mean learning a new tool.

The rebuild started in 2020. Its first product, Mailbird for Mac, launched in October 2024 and reached the Mac App Store worldwide in September 2025. Mailbird Next now brings that same foundation to Windows.

It's built for anyone juggling more than one inbox: people who use different email providers like Yahoo and Gmail at the same time, professionals with work and personal addresses, and small teams who live in email all day. It works with Gmail, Outlook, Microsoft 365, iCloud, Yahoo, and any IMAP account.

What's in Mailbird Next

Everything below is in the app on launch day. Features marked ★ are Premium; you can try all of them free for 7 days.

One inbox for every account

Add all your email accounts and read, reply, and organize from a single unified inbox. When everything is in one place, email stops being a scavenger hunt and becomes a list you can actually work down. The free version works with one account; Premium adds unlimited accounts.

Your apps, next to your mail ★

Add WhatsApp, Google Calendar, Asana, Dropbox, and dozens of other apps to a side panel beside your inbox. Reply to an email, tick off a task, and check your schedule without switching windows. You can also add your own custom apps.

Know when your email was opened ★

Unlimited email tracking shows which messages were read and when, so you follow up on the ones that weren't and leave the rest alone.

Manage email on your schedule ★

Snooze a message until you're ready for it, schedule a send for Monday morning, undo a send you regret, and use snippets for replies you write every day.

Search every account at once ★

Because your accounts are unified, one search covers all of them. Advanced search and attachment search find the old email or the file you need.

Getting Things Done for email

Clear your inbox in two minutes in the Mailbird mobile app. Everything you sort will be waiting in Mailbird for desktop, in the list it belongs to, across every account.

Keep your email to yourself

Your mail is stored on your computer, never on Mailbird's servers. The Privacy Hub blocks pixel trackers, so senders can't tell when you opened their message.

Make it yours

Choose from nine color themes and five layouts, in light or dark mode, and set the zoom to whatever suits your eyes.

Also included

See the features page for the complete list, including what's in Premium.

Mailbird mobile apps

Next is growing into one Mailbird across Windows, Mac, and your phone. The Android app is in public beta today, ready for you to test-drive, and the iOS app is almost here. Now all your accounts can be in one inbox on the go, too!

Your AI, on your terms

Mailbird Next lets you connect the AI app you already use, such as Claude, ChatGPT, or Cursor, through MCP. It stays off until you switch it on, it runs locally on your computer, and Mailbird never trains on your email.

Once connected, your AI app can help you read your mail and attachments, draft replies, archive messages, and unsubscribe from lists, but only when you ask. Actions that change your mailbox are gated, and nothing is sent without your explicit confirmation.

It's private, opt-in AI: you decide if it's on, what it looks at, and what it's allowed to do.

Free to start, Premium when you want more

Mailbird Next is free to download. The free version has no time limit and works with one email account and the basic features.

Every new account gets all the Premium features free for the first 7 days. After that, you can keep using the free version or go Premium for unlimited accounts, app integrations, email tracking, and the rest of the ★ features above. You can switch between plans at any time, and if you're unsure which fits, our Customer Happiness Team will help.

Current plans are listed on our pricing page.
