Keep Your Inbox Clean with eM Client Inbox Categories

Between various emailing lists, email notifications from multiple social sites, and other “non-email” content, our email inboxes have become quite bloated. One way to sort out different kinds of emails is inbox categories. This article will show how inbox categories function in the eM Client desktop and mobile applications and how to make the most of the categories feature.

Keep Your Inbox Clean with eM Client Inbox Categories

Missing Messages from Inbox?

You might have noticed that there are fewer messages than you expected in your inbox. Before panicking, consider checking the top tab of your inbox – if the Categories feature is enabled, the message might have been assigned a category and sorted into a separate tab.

The category view helps you filter out the marketing newsletters you subscribed to, occasional notifications from social networking sites, and other emails that typically aren't a priority.

The default categories tabs for Gmail accounts are Primary, Promotions, and Social. For all other accounts, they will be Primary and Other. But you can customize these, of course. We’ll illustrate how further down in this article.

Default Gmail account categories view:

eM Client: Mail list categories Gmail

Default non-Gmail account categories view:

eM Client: Mail list categories non Gmail

The default Gmail account layout, which we call “Gmail style” in eM Client, copies the same Gmail inbox categories view you might be used to from the Gmail webmail.

The default view for all other accounts is very loosely inspired by Outlook’s “Focused Inbox”, with Primary containing the more important categories that might require your attention first and the rest in Other tab.

The view can always be changed to a different one that you prefer – for example “Gmail style” for all accounts.

Changing and Disabling the Categories View

The category tabs view can be customized for each email account separately in the main window by right-clicking the tabs or the top of the message list:

eM Client: Category tabs settings

At the bottom part of the drop-down menu, you will also find the “Hide Categories Bar” option which allows you to instantly turn off the categories view in the specific inbox.

Inbox Categories in the eM Client desktop app

eM Client supports Personal, Promotions, Social, Updates, and Forums categories. Any messages that have not yet been categorized will be in the “Not categorized yet” state. This means the categorization process has not been started at all (for example after importing a large number of messages). Messages that do not fit into any of the available categories will be shown as having “No Category”.

How to turn off inbox categories?

The categories feature can be enabled (and disabled) for the whole app by heading to Menu > Settings > Mail > Categories and checking the “Show categories” option:

eM Client: Settings - Show categories

Assigning and Changing Categories

When the Categories feature is enabled, messages are sorted into categories automatically. In the case of Gmail accounts, the sorting is done by Google and then synchronized with the eM Client app. All non-Gmail accounts’ messages are sorted by eM Client’s algorithm.

If the automatic categorization fails, try using the Repair function – right-click on the Inbox and select Properties > Repair > Categorize messages.

And how to move emails from Promotions to Primary, for example?

Changing category for individual messages can be done either by right-clicking the message and choosing “Category”, after which the available categories can be chosen:

eM Client: Change category

Or change the category by dragging and dropping the message to the target tab.

Once you drop the message to the intended category tab (or confirm the category for combined tabs), a confirmation window will pop up. It shows the different options you have in terms of whether the category change will be applied to future or older messages as well, or just the selected message:

eM Client: Change category confirmation

By default, the drag-and-drop category change creates a new rule for all future messages received from or sent to that same email address. These messages will be assigned the target category.

You also have the option to change the category for all past messages associated with that email address. To do this, simply press and hold the “Shift” key while dragging and dropping the message.

Additionally, if you press and hold the “Alt” key (on Windows) or the “Control” key (on macOS) while dragging and dropping, only the category of the selected message will be changed, and no new rule will be created.

In case of combined tabs (Primary, Other, or All), a pop-up window will open, asking to specify the category first:

eM Client: Pick new category menu

Note: Changing categories for messages in Google accounts is only available with paid licenses.

Custom Rules for Categories

In Settings > Mail > Categories, you will find all of your Custom rules and category settings in one place.

By clicking the “Modify” button in the Custom Rules section, you can edit the Custom rules:

eM Client: Modify category
eM Client: Filter Personal mails menu

Each category can be manually assigned here – it is also possible to limit the categorization beyond the default rule (“Sent to and received from”) to only “Received from” or “Sent to

Category rules can only be applied to a full email address – they do not work with domains or partial email addresses.

Note: For Gmail accounts, the custom category rules cannot be viewed at all.
This is how the Gmail categories work: the eM Client app sends the new category rule information to the Google server, which saves and applies them for future messages, but it does not provide a way to access and view them, not on the web interface nor third-party apps like eM Client.

Additionally, changing categories for messages in Google accounts is only available with paid licenses.

Customizing Category Tab Defaults

In the Categories section, choose which category tabs will be shown by default:

eM Client: Cutomize category tab settings

Additionally, by selecting the “Custom” option in the drop-down menu, you are able to separately choose categories tabs’ visibility for your Gmail and non-Gmail accounts and global folders.

For all accounts and folders, it is possible to also specify which categories will be displayed under the Primary and Other tab (in the case of the Primary & Other tabs view), based on your priorities:

eM Client: Cutomize category tab settings

Below the tabs view settings, you will also find the display options for recent and unread messages. You have the option to choose which of these will be displayed next to the category tab’s name – the number of recent messages, the number of unread messages, or neither.

The message counter’s style can be adjusted as well – a badge showing the number, a number in parenthesis, or a dot without any number to indicate there are unread or recent messages in the particular category tab.

Inbox Categories in the eM Client mobile app

The mobile app offers nearly identical settings to the desktop app.

The view of all categories can be changed by tapping and holding the top of the inbox – the Category tabs menu will pop up:

eM Client: Category tabs in eM Client Mobile

You will find the Categories section in the main settings menu:

eM Client: Mobile categories settings
eM Client: Mobile categories settings

The default visible tabs can be adjusted as well:

eM Client: Default mobile tab

By tapping on the Custom Rules option, adjustments can be made to the Custom rules of each category:

eM Client: Mobile custom rules
eM Client: Mobile custom rules
eM Client: Mobile custom rules

After selecting a message in the Inbox, you can re-categorize it – tap the three dots icon in the upper right corner, then tap the Category option and select which category you wish to assign the message:

eM Client: Change category
eM Client: Change category
eM Client: Change category

Inbox categories are a useful tool that will help you prioritize which emails you view primarily and which ones you postpone for later.

Thanks to the inbox categories feature, various notifications from forums and pesky promotional emails will not clutter your inbox anymore. Category tabs can be adjusted for each of your email accounts, making it easy for you to set different styles for work and personal inboxes.

And if using the categories just isn’t your thing? Turn them off in a few clicks. With eM Client, your inbox will always look just the way you prefer.
