Apple Mail is a free client that comes preinstalled on every new Mac sold—that in itself makes it a solid default choice for Mac users. The application's trademark postage stamp icon hasn't changed a lot over the years, and despite steady development from Apple, the client still retains its old-school feel.
Aside from the attractive lack of a price point, Apple Mail is often chosen for its simplicity. It's a basic email client with support for a range of services including the company's own iCloud Mail, Gmail, Yahoo! The user interface is clean but nothing special, with mailboxes, folders, and accounts accessed via the sidebar. Messages are presented as threaded conversations that are separated by subject.
Unified mailboxes let you see all of your incoming, sent, and draft mail in a single list by default, or you can pick specific mailboxes if you prefer. One standout feature is the inclusion of smart mailboxes that filter your mail based on rules of your choosing. You can then quickly access your filters via the sidebar beneath the Smart Mailboxes heading. There are plenty of other bells and whistles too. Handoff with iOS allows you to seamlessly pick up where you left off on your mobile device, and Mail Drop uploads large attachments to iCloud for easier sharing.
For another free option, consider Mozilla Thunderbird , an email client from the developers of Firefox. Thunderbird is a free and highly extensible email client that feels like a classic version of Outlook. Some of the more useful features include tabbed email, sending of large attachments using cloud storage, and the ability to greatly change the look and feel of the app.
Airmail takes the basic premise of an email client like Apple Mail and builds on it with more modern features and an emphasis on speed.
You can browse and reply to all of your mail from a single unified inbox, which brings all of your accounts together in one place. When you compose a new message, you'll use a dropdown to select which of your connected accounts and personas you want to send from. Airmail is a fast and clean email client that doesn't bog you down with features you don't need.
If you're familiar with Gmail's shortcuts, you'll be off to a flying start, but you can also set your own custom shortcuts to navigate with your keyboard. Conversations are threaded by subject, with a Quick Reply button for replying to a message in-line. Click the small speech bubble icon, and a reply field will pop out, which makes it easy to respond to a specific message in a thread without losing your place.
Composing a new message or "full" reply takes place in a separate window, much like Apple Mail. You can drag and drop your attachments into this window, with full support for iCloud's Mail Drop link sharing. Snooze email directly from your inbox so that it appears at a more relevant time, which you can define within Airmail's preferences. Turn your messages into to-dos or memos using Airmail's built-in organizer in two clicks or using a keyboard shortcut. The organizer lives at the bottom of the sidebar and looks and feels just like an inbox for your schedule.
You can even access your Google Contacts directly in the app using Google's search-as-you-type functionality. If you're willing to spend a pretty penny, we'd also suggest Newton formerly known as CloudMagic. Spark is a desktop email client that brings Gmail-like features to Outlook, iCloud, Yahoo! It includes a smorgasbord of conveniences, like the ability to snooze an email for later with a click and smart sorting of your inbox into categories like "Personal," "Notifications," and "Newsletters.
Spark for Teams is where the mail app takes on a whole new life. The team behind Spark hasn't just built a convincing email app—they've developed a collaborative email platform. This includes unique features like the ability to comment privately with team members on email in a small chat box to the right of the message. Collaborative composing allows you to invite other team members to collaborate and proofread your email in real time just like Google Docs.
Create secure links that point to specific threads or messages, and share them with your team. With these features, Spark could even function as a lightweight CRM solution. If you're looking for an email client specifically for shared inboxes vs. Front allows you to connect mailboxes to channels, then assign team members to those channels.
It's a powerful tool that can spread the heavy load of a busy inbox across your entire team. Canary Mail is an email client for the security-conscious individual due to its support for end-to-end encryption using PGP. With encryption enabled, nobody aside from the intended recipient is able to read your message—not even your email provider. Encryption can be enabled with a single click while composing your message. In addition to privacy features, Canary offers a range of tools to improve your productivity.
This includes the Focused Inbox, where Canary learns which emails are important to you and hides the rest with one click on the Focused tab at the top of the window. You can also search your mailboxes using natural language processing think: "photos from Dad last month" to find things quickly. There are a host of other useful features that elevate Canary beyond its security-focused roots.
Use Microsoft's included templates or design your own so you can roll them out time and time again. The turn off about this app is the ads. VERY cool indeed!! All this, plus all the goodies Google packs into the web version like chat support, keyboard shortcuts, and industry-leading spam protection. Latest Mountain Lion Hints
You can track your emails to find out if they've been read, snooze incoming messages for later perusal, and unsubscribe from newsletters by clicking the thumbs down icon at the top of the message. Canary is suitable for use with Gmail, iCloud, Office , Yahoo! Mail, and IMAP accounts.
Unibox describes itself as a "people-centric" mail client, something it achieves by grouping your messages by sender in reverse chronological order. Instead of seeing your inbox as a list of messages and subject headings, Unibox shows you a list of recent correspondents and the number of unread messages within each conversation.
The app presents everything—including email composition—in a single window view. Respond to an email, and a compose box will slide into view, providing just enough room to type your response and still read the original email thread. This simplicity in design is seen throughout the app, from truncated message threads to the ability to view all files exchanged between yourself and another contact by toggling either of the attachment views at the top of a thread. It's not possible to view your inbox like a standard inbox in Unibox.
There's nowhere to view all of your outstanding drafts either you'll need to find the contact, then open the editor to view them. This is a radical conversational approach to email, and assuming your own email habits are compatible, it works. Also available on SetApp. If you have an Office subscription, you're already paying for Microsoft Outlook.
That should be reason enough to give Microsoft's full-fat email client a go, since it works with Microsoft accounts, Gmail, iCloud, and Yahoo! Outlook maintains the same familiar design that hasn't changed much over the last decade, which is why it may feel a bit stagnant in the UI department.
There are many new features to get stuck into though. Focused Inbox is one such trick: It separates your inbox into two tabs, placing all the email that Outlook perceives as important on the Focused tab. Twitter-like mentions let you tag people, with Outlook automatically adding their email addresses in the "To:" field, which can come in handy if you're often adding coworkers to emails. You can even use customizable two-finger swipes to cut through your email. Like most Microsoft Office-branded products, Outlook includes excellent support for mail templates. Use Microsoft's included templates or design your own so you can roll them out time and time again.
And many of the modern email features that have emerged over the past few years haven't escaped Microsoft's gaze either: follow-up reminders, delayed sending, email scheduling, and support for SVG graphics, to name a few. Outlook delivers all of these mail features, plus a calendar, chat, task manager, and note-taking.
You can even create Office groups right in Outlook now. If you take an "everything including the kitchen sink" approach to email, Outlook is the client for you. It includes the ability to group accounts together into custom unified inboxes, tabbed email, a focus mode for hiding unimportant email, and the ability to quickly post mail content directly to other services like Dropbox, Trello, and Instagram. The email access domain is completely independent of the web access domain and will look something like this: xxxx-xxxx.
The "xxxx-xxxx" string will be a series of randomized letters. This will be totally unique to your specific Grid.
