5 Best Email Apps for Mac

Mac users have always been known for their high demands when it comes to apps. They refuse to settle for apps with a poor user interface and even poorer performance, which is why they use Mac computers (macOS 10.10+ including macOS 12 Monterey) in the first place. Unsurprisingly, there are many best email apps for Mac to choose from, each offering a slightly different set of features in a slightly different package.

1. Spark

Spark presents itself as an email client of the future. What’s so futuristic about this Mac email app is how it organizes emails. Using advanced algorithms, Spark is able to sort emails according to their content, so that your personal emails are not mixed with newsletters and notifications. This makes it a lot easier to read and reply to important emails and ignore everything else.

Simply click the Undo button to undo the last action. With Spark, you can search for specific emails using natural language, so searches like “attachment from Peter” are entirely possible.

Spark is great for teams since it supports private in-line comments, shared emails, and advanced email collaboration with real-time editor and a side-chat to talk to colleagues. As long as you’re fine with 5 GB of team file storage and only 2 active collaborators, you can use Spark for free.

Unlike all other Mac email apps featured in this article, Clean Email isn’t an email client. Instead, it’s a bulk email organizer whose purpose is to help you get rid of emails cluttering your inbox. Clean Email accomplishes this by grouping similar emails together, creating easy-to-review bundles that you can manage as if they were a single email. So, instead of removing, archiving, moving, or labeling hundreds or thousands of emails individually, you can manage them in bulk.
