What is Mailbird?

Mailbird is a desktop email client that puts all your email accounts in one place.

Think of it like a control tower for your inbox.

You add Gmail, Outlook, Yahoo Mail, iCloud, and even Exchange accounts. All your messages show up in one unified inbox.

No more tab juggling.

The Mailbird team built this email client for Windows users first. In September 2025, they launched Mailbird for Mac too.

It works with all major providers. The app integrations let you bring in Google Calendar, WhatsApp, Slack, and Asana right inside the email app.

Unlike existing email clients like Outlook, Mailbird focuses on speed and a clean UI over heavy features.

Who Created Mailbird?

Andrea Loubier and Michael Bodekaer launched Mailbird in 2013.

The story: they were frustrated with bloated email clients that wasted time. So they built their own.

Today, Mailbird has:

• 4.8 million email professionals using it daily
• Annual updates with new features
• A new Mailbird for Mac version (launched Sept 2025)

The company is based in Bali, Indonesia. The Mailbird support team works fully remote.

Top Benefits of Mailbird

Here is what you actually get when you use Mailbird:

• Save hours every week: Manage multiple email accounts in one unified inbox. No more switching tabs between Gmail, Yahoo Mail, and your Outlook account.
• Stay focused: The clean interface and clean UI cut out the noise. You see only what matters in your inbox.
• Easily manage e mail accounts: Add unlimited accounts with the premium email client plan. You can easily access all your messages from one location.
• Work faster: Keyboard shortcuts let you fly through messages. The Speed Reader tool shows email content one word at a time.
• Connect popular apps: Built-in app integrations bring Google Calendar, WhatsApp, Slack, and 30+ web apps into one app.
• Protect your data: Mailbird stores all sensitive data only on your windows pc. Nothing sits on their servers.
• Look great while working: Customize the client’s appearance with themes, fonts, and notification sounds.

Best Mailbird Features

Here are the standout Mailbird features that make this email app worth your attention.

1. Advanced Search Operators

Lost an email from 6 months ago? No problem.

The advanced search feature lets you find any message in seconds. You can search by sender, date, attachment type, or keyword.

Even better, search works across all your email accounts at once. No need to log into each single account separately.

This is one of the features I used most during testing.

2. Calendar & Scheduling

Mailbird has a built-in calendar app.

You can sync your Google Calendar and view appointments next to your emails. No more flipping between apps.

Create events, set reminders, and accept meeting invites without leaving your inbox.

This is great for Google Workspace users who live in their calendar.

3. Email Management

Snooze emails for later. Move messages between accounts. Set custom rules to sort incoming mail.

You can also block unwanted senders with one click.

Email templates save you from typing the same reply over and over. I built 8 templates and saved hours each week.

You can snooze emails to read them later when you have time. Unread emails get a clear count in the sidebar so you stay focused.

4. File Storage & Management

Attachments can be a mess.

Mailbird connects to Dropbox, Google Drive, and OneDrive. You attach big files without bloating your email.

The attachment search tool finds any file you have ever received. Just type the name or file type.

This works across nearly all your email accounts at once.

5. Task Management

Turn any email into a task.

Mailbird connects to Asana, Todoist, and Trello. You can create tasks straight from your messages.

No more copying and pasting between apps. The whole workflow lives in one tool.

For someone managing client work, this is gold.

6. Email Tracking

Want to know if someone opened your email?

Mailbird supports real-time email tracking. Premium users get unlimited tracking on all the features.

You see when, where, and how often someone read your message. This helps with sales follow-ups and important client emails.

It is one of the most useful Mailbird features for sales pros.

Mailbird Pricing

Mailbird offers three plans. Here is what each costs:

Free trial: No free trial, but a 14-day money-back guarantee on all paid plans.

Money-back guarantee: Yes, 14 days for any reason.

📌 Note: The free version is limited to one email account and lacks many features available in the paid versions. To easily manage multiple emails, you need the premium plan.

Is Mailbird Worth the Price?

For most Windows users who manage several email accounts, yes.

The Premium subscription costs less than $5 per month. That is cheap for a tool you use every day.

You will save money if: You plan to use Mailbird for more than 3 years. The Pay Once license pays itself off after about 2.7 years.

You might overpay if: You only have one single account or rarely use email.
