Features and Performance Analysis


Manage All Your Emails in One Place

A unified inbox is a feature that allows you to manage all of your emails from multiple accounts in one place. This convenient feature supports any email account, whether it’s Gmail, Outlook, Yahoo, or any other IMAP or POP3 account.

You can also customize your communication by using different identities and signatures for each account. This means that you can have different sender names, email addresses, and signatures for different accounts.

App Integrations

The app integration feature allows you to connect Mailbird with other popular services, such as WhatsApp, Facebook, Twitter, Dropbox, Google Calendar, Asana, Todoist, and many more. This means that you can access all of these services from one place, without having to switch between different windows or tabs.

This way, you can streamline your workflow and boost your productivity.

However, the app integration feature also has some drawbacks that you should be aware of. For instance:

  • Some of the apps are not very well integrated with Mailbird, and the functionality is limited or nonexistent. For example, you cannot reply to WhatsApp messages from Mailbird, or edit your Google Calendar events from Mailbird.
  • Most of the apps are just web services running inside Mailbird, and they may not offer the same features or performance as their native versions. For example, you may experience slower loading times or glitches when using some apps in Mailbird.
  • Some of the apps may require additional permissions or subscriptions to work with Mailbird. For example, you may need to sign in with your Google account or pay for a premium plan to use some apps in Mailbird.

AI-Powered Email Writing

Mailbird offers ChatGPT integration in its email clients, so you can you write high-quality emails immediately. This feature uses OpenAI’s GPT-3 language model to generate email content based on your input and preferences. You can use ChatGPT to write emails for different situations, such as:

  • Requesting a meeting
  • Following up on a project
  • Giving feedback
  • Apologizing for a mistake
  • Asking for a favor, And many more

ChatGPT will help you craft professional and personalized emails that get your message across effectively and politely. You can also customize the generated emails to suit your style and tone. With Mailbird’s ChatGPT feature, you can save time and effort and improve your email communication skills.


Email snoozing is a feature that allows you to temporarily hide an email so that you can focus on other emails. You can then choose to have the email reappear at a later time. This is helpful for emails you don’t need to deal with immediately, but you don’t want to forget about both.

To snooze an email in Mailbird, you can right-click on the email and select “Snooze,” use the action bar at the top of the email, or the shortcut Z. The snoozed email will be archived in the snoozed folder until the time you specified.

Snoozing emails can help you to stay organized and reduce clutter in your inbox. It can also help you to prioritize your emails so that you can focus on the most important ones first.

Speed Reader

Speed reading is a technique that allows you to read text quickly and efficiently, Mailbird has a built-in speed reader that can help you read your emails faster.

To activate the speed reader, click on the lightning icon at the top of any email. The speed reader will display the words of the email one by one at a fast pace. You can adjust the speed and control the reading process as you wish.

Speed reading can help you save time and improve your comprehension. It can also help you to read more emails in a shorter amount of time, which can boost your email productivity.

Here are some additional tips for using the speed reader:

  • Start with a slow speed and gradually increase it as you become more comfortable with the technique.
  • Take breaks every few minutes to avoid eye strain.
  • Practice regularly to improve your speed and comprehension.

Note: Speed reading is not a magic bullet. It takes practice to improve your speed and comprehension, and you may not be able to achieve the 800 words per minute rate right-away. However, regular practice can significantly improve your email reading speed and efficiency.

Attachment Search

This feature lets you find any attachment in your Mailbird account in seconds. Here’s how it works:

  1. Click on the paperclip icon at the top of your inbox.
  2. See all the attachments from all your accounts in one place.
  3. Filter them by type (images, documents, videos, spreadsheets, presentations, PDFs), size (small, medium, large), or date (today, yesterday, last week).
  4. Search by keywords or phrases.

For example, if you need an invoice, type “invoice” in the search box. Or, if you want to find a presentation you sent to a client last week, type “presentation client last week.”

Attachment search is a valuable tool for anyone who receives or sends a lot of attachments. It saves you time and hassle by helping you find what you need quickly and conveniently.

Dark Theme

The dark theme is a setting that allows you to change the color scheme of Mailbird to a Dark or Lite theme. You can access this feature by clicking on the sun/moon icon at the bottom left corner. The dark theme will change the background color to black and make the text white. The Lite theme will do the opposite. The dark theme can help you reduce eye strain and save battery life.

You can access a list of all the shortcuts by pressing Ctrl + / on your keyboard. You can also customize the shortcuts to your preference by going to the settings menu.
