Spark on MacSource: iMore

Emailing is probably the activity we do the most on our computers, including the best MacBook. Even if you don't work on a computer during the day, you probably sit down in front of it to check your inbox at the end of the day. If the Mail app that comes with your Mac doesn't provide the features you need, you're in luck. There are dozens of great email apps in the Mac App Store. We've tested many of them, and these are our favorites. Each one has a little something special that makes it unique.

Best Mail Apps for Mac: Polymail

Polymail for Mac offers a fantastic interface with cute buttons everywhere, so you don't have to think about what to do next. It actually looks like it belongs on a mobile device, except that you click the buttons instead of tapping them. (There is a mobile version also.)

A fourth section appears whenever you select an email, which displays all of the past correspondences you've had with that particular contact or group of contacts. It's great for quickly tracking down something you've discussed in the past.

You can set up new mail with a pre-made template, send calendar invites, get notifications when someone has read your email, and schedule an email to be sent at a later time.

You can also write or respond to emails with rich text formatting. So, if you want to change the font, add bold lettering, bullet point a section, or even slap an emoji in there, it's all available right from the toolbar at the top of your new email.

Polymail can be used for free for seven days. From there, subscriptions start at $10 per month. If you are a heavy email user and these features entice you, give the free trial a run to see if it's worth your money.

Best Mail Apps for Mac: Spark

SparkSource: iMore

Spark has this "Smart Inbox" feature that separates mail into categories: Personal, Notifications, Newsletters, Pinned and Seen. That is, any email that is from someone in your contacts or otherwise looks like a personal email will be filtered to the top of the inbox list. In a separate section, emails that look like alerts from companies you deal with, like your gas company or Amazon, include an alert or notification. Below that, you'll see a section called "Newsletters," which is exactly that. Below that, there are emails you've flagged or tagged as important in some way. Lastly, emails you've seen but haven't moved to another folder.

Spark also allows you to snooze an email and come back to take care of it at a later time. This is invaluable when you regularly get emails that you need to respond to but don't have time for until the end of the day. I use it all of the time.

It also has gesture-based actions for getting to inbox zero. You can swipe to the right or left to delete, archive, pin, or mark an email as unread.

Spark is best for people that like to have their inbox organized before they go through and move emails to new folders, address them, or delete them entirely. If that sounds appealing to you, try Spark.

If you have one or more Gmail accounts, you should consider switching to Kiwi. This all-in-one triumph brings the look and feel of Gmail for the web to the desktop in the form of an app. With the service's unique Focus Filtered Inbox, you can view your messages based on Date, Importance, Unread, Attachments, and Starred. In doing so, you can prioritize your emails in real-time.

Kiwi for Gmail is free for a basic account, which allows you to use one Gmail account. Kiwi for Gmail Premium extends this to six accounts and is $34.

Perhaps the best reason to use Kiwi for Gmail is its G Suite integration. Thanks to the app, you now get to experience Google Docs, Sheets, and Slides as windowed desktop applications. Kiwi is available for Mac and Windows.

This well-received email app has been designed for professionals, but anyone with more than one email account should consider using it. For Mac and Windows, Postbox works with any IMAP or POP account, including Gmail, iCloud, Office 365, and more.

Best Mail Apps for Mac: Hey

Hey Email MacSource: iMore

Unlike anything else on the market, Hey disrupted the email scene in 2020. Its focus is to provide customers with the tools to make sure only the most important emails are front-and-center.

It does this by providing you with an @hey.com email address that you can use to forward emails from your other accounts. From there, Hey makes it relatively pain-free to weed out any unnecessary emails.

The Hey app isn't for everyone, especially with its price of admission — $99 per year! However, it does come with a 14-day trial, so you have enough time to see if it's right for you. It's is also available for mobile, which is covered by the same yearly fee.
