The native Mail app on macOS systems is an excellent mail app. With the addition of features like email scheduling, undo send delay and email snoozing, it has come closer to some of the more powerful email clients. But no app can be perfect, and the Mail app has its drawbacks. If you deal with tons of emails every day, and the Apple Mail app no longer feels viable, here are the best email apps for Mac to use in 2023.

Top email apps for Mac in 2023

Before we begin our list, I just wanted to add a quick comment on the features that we looked for when searching for the best email clients for Mac. Email clients are one of the few categories of apps where we felt that the overall design was as important as features itself, and hence it played a big role in our selection criteria. No matter, how powerful an email client is, if it’s not able to present the information in a pleasing and easy to discern way, users will find it hard to use.

Another important feature for a third-party email client is its support for multiple accounts types including Gmail, iCloud, Yahoo, Exchange, IMAP, and more. The email client should also be fast at syncing emails. The last thing you want is delayed emails. Apart from these basic features, the email client should bring advanced powerful features such as integration with third-party services, auto-categorization of emails, a customizable interface, and so on.

Based on these basic criteria, we started our search for the best third-party email clients for Mac and here are the best 5 that we found.

1. Spark

Spark has always been one of the best email apps for Mac. With its version 3.0, Spark Mail has been redesigned from the ground up and focuses on helping users reach Inbox Zero. It features a smart inbox that separates priority emails from non-priority emails, allowing you to easily tackle the emails that matter.

We also love the smart search feature in Spark, which is ultra-fast, and finds the email we are looking for in seconds. Other features of the app include easy keyboard navigation, a universal action button, group threads, threads muting, and more.

4. Thunderbird

Thunderbird by Mozilla is one of the most powerful email clients for Mac. However, its old-school design has always put off new users. If you haven’t used the app in a long time, you should test it again. Over the past two years, it has released several updates that have added new features and refreshed its user interface.

The app is easy to set up and use, and many of the features which were previously only available via add-ons, are now native to the app. You can easily create contacts with its one-click address book, view emails in easy tab views, quickly filter your emails and perform better search.

5. Canary Mail

Canary Mail is one of the most secure and beautiful email clients on Mac and I loved using it during my testing period. Most of us don’t realize this but email, by design, is not the most secure platform to converse with each other, and if security is a big concern for you, you should try Canary Mail.

Canary mail solves the privacy problems by bringing end-to-end encryption which ensures that only you and the person you're communicating with can read what is sent, and nobody in between, not even your provider.

The best part about Canary Mail’s encryption is that it can be activated with just one click. If you want even more security, Canary Mail also allows you to use manual keys which a sender can share with a recipient privately. This method is a bit more technical, however, it’s also the most secure.

Canary Mail has also an integrated AI that learns your email writing behavior and can write emails, surface important emails, automatically silence spam emails, and more.

When it comes to other features, Canary Mail doesn’t disappoint. It brings an arsenal of power user features including focused inbox which gives you access to important emails first, a powerful natural language search, smart filters, bulk cleaner, one-click unsubscribe, support for email templates, snooze, integrations with third-party apps such as Google Drive, Dropbox, and Keybase, and more.


  • End-to-end encryption for safer emails
  • Integrated AI features
  • Fast launch time
  • Excellent email triaging features


  • AI still has a long way to go
