Postbox Features

The Quick Bar is like macOS Spotlight but for common mail actions. Type a few characters in the Quick Bar, then autocomplete against the suggestion. Supported actions include Quick Move, Quick Copy, Quick Post, new Tag/Topic, new Gmail Label, and Quick Folder Switch.

File messages by typing the name of the target folder in the Quick Bar. Only the first few characters are needed, then auto-complete against suggestions offered.

Like Quick Move, Quick Copy will copy a message to the target folder entered in the Quick Bar. Type the first few characters of the target folder, then auto-complete against the suggestions to copy the message.

Postbox supports gestures for those using macOS with a trackpad or other device that supports multitouch gestures. These four gestures are supported: Archive, Reminder, Junk, and Delete.

Unlike other email apps, Postbox's swipe actions can be performed on multiple messages simultaneously.

If Postbox detects a "List-Unsubscribe" attribute in a message header, it displays an Unsubscribe link next to the sender’s address, so you can unsubscribe with just one click.

You can move messages from the Inbox to a dedicated Archive Folder by clicking the Archive button in the toolbar or via the "a" keyboard shortcut.

Postbox provides the most complete filtering rule sets on the market – a power user's dream. Filters can be created per account or globally across all accounts and run automatically, manually, or periodically. You can add contacts to a filter on-the-fly without opening the filter editor.

Postbox Account Groups lets you organize accounts into groups. Create separate groups to hold your "personal" and "work" accounts, then unify them into one view.

The Focus Pane lets you focus on what you need, and nothing else. The Focus Pane zeros in on messages by attribute (such as being unread or having an attachment), contact, topic, and date.

Postbox fully embraces message organization and management via tags/keywords called Topics. When you assign a topic to a message, it's also applied to other messages within the conversation, in addition to all future replies. Topics can be used for organization, views, search, and message filtering/rules.

Postbox supports Gmail or GSuite labels and matches much of the organizational behavior of Google accounts online. All Mail and Important folders are also supported.

Postbox lets you create reminders where it matters most — your Inbox! Create new reminders, annotate existing ones, and then pin reminders to the top of your message list so they're not forgotten.

A Smart Folder displays email messages that are stored in other folders and that meet certain criteria you specify. For example, a Smart Folder could include all the messages you receive from a specific person, regardless of which folders the messages are stored in.

Postbox's Social view, located in the Focus Pane, lets you browse updates from your social networks; perfect for monitoring your brand, killing time during lunch, or when you're in power triage mode and need to clear out unnecessary clutter.

Another Focus Pane feature, the Subscription View, organizes messages from the services you subscribe to and presents them in one convenient view. Great for unsubscribing from newsletters en masse.

Use Quick Post to forward email content to hundreds of applications and services, like Evernote, Slack, Todoist, and many more. Quick Post supports any service that can accept an email, or integration through Zapier or IFTTT.

Best of all, Quick Post happens in the background without the need for a compose window. You can even set your Filters to run Quick Post actions to create the ultimate workflow.

Quick Reply lets you reply to a message without opening a compose window – perfect for short, snappy responses like "I'll see you at eight," or simply "Thanks!" And it all happens inline within a message or conversation.

Supported in both Quick Reply and Compose windows, Send & Archive will automatically archive the message you're replying to – a great way to keep your inbox tidy.

Responses are pre-canned text/HTML snippets that can be reused within message replies. Placeholders automatically populate with data from the message itself –or– your own data through the custom fields you create.

Only in Postbox

We include 70 Professionally Written Email Responses that anyone can customize and use. You'll receive emails for finding a job, hiring, making introductions, reaching out to investors, and sales.

The Image Scaling feature in Postbox 7 resizes large inline images with just a few clicks. Image scaling can be performed on a "per-image" basis, as opposed to the all-or-nothing approach found in some other email clients.

Since ISPs have size limits for messages sent through their servers (for example, Gmail places a 25MB limit), Postbox can display a warning if you exceed a certain threshold. The message size indicator will display the total message size, including text and images.

Postbox contains a number of Image Effects that will enable you to create beautiful emails and newsletters. Effects include scaling, float, margin, flip, rotate, photo effects, frames, and shadow.

Emojis add personality to any email, and Postbox has the fastest and easiest way to insert Emojis into your messages. Type a colon, followed by the name of the Emoji you wish to use, then auto-complete against your desired selection. Fast, easy, and fun! 👍

Press and hold any key to bring up a set of international characters for easy input. We've also updated our translations for German, French, Spanish (Spain), Italian, Dutch, Portuguese (Brazilian), Russian, and Swedish.

Type "HTTP" or "www" in the Compose window, and Postbox will auto-complete the URL from the links it can find in your messages. Your entire mail store now serves as a database for links that you can easily share with others.

The domains are specified per account, which provides for fine-grained control over how you're notified of potential addressing mistakes.

Our Composition Goals feature provides a user-configurable character/word counter and stopwatch that indicates to users when a message being written exceeds the desired length or has taken too long to write.

To protect your privacy, Postbox 7 has an Anti-Tracking feature that will alert you when tracking tools are used within a message.

Use Anti-Tracking to prevent pesky salespeople from knowing if and when you open a message.

Postbox can filter junk mail from your Inbox based on what it learns from you when you mark email messages as "junk" or "not junk."

You can use identities (also known as "aliases") to prevent junk mail from being sent to your primary email addresses. For example, you can use your primary email address for emailing friends and family but use an email identity for online registrations, purchasing products, and joining mailing lists.

Show contacts by "Display Name," "Email Address," or "Display Name and Email Address" for contact presentation in the message list and message header envelope. By showing the email address, you can more quickly determine the sender's legitimacy.

For our power users, Postbox supports a full suite of keyboard shortcuts. Postbox also supports an alternative suite that maps to Gmail's keyboard shortcuts.

Limit the number of messages that will download per folder to keep your message list clean.
