Outlook rules: Optimize your correspondence!

By

9 a.m., at the office.

As usual, you take a sip of coffee before logging into your email, not without some trepidation. Deep down, you know what awaits you: a cacophony of emails, where urgent correspondence, newsletters, and customer follow-ups battle for your attention. You open your inbox and suddenly feel like you're caught in a virtual whirlwind...

But today, dear internet user, the confusion is over thanks to email rules. These easy-to-set-up automatic settings can help you restore harmony to your inbox and optimize your email management.

Here are our top tips for organizing your emails and the steps to follow to create a rule in Outlook.

(To find out how to set up an Outlook rule, go to the section "How Do I Create a Rule for Emails in Outlook?")

How Can You Organize Your Emails Effectively?

Setting a rule in Outlook

Did we mention that we're good friends with Marie Kondo? We're not kidding! In fact, the other day, we asked her for her opinion on the importance of organizing emails. The "queen of tidying" is adamant: a well-managed inbox means a clear mind and good energy flow.

01Set Aside Time for Organizing

The first tip for a tidy inbox and smooth communication is to plan ahead! Set aside some time during the day, week, or month to clean up your inbox and sort through your emails.

By consciously scheduling time in your calendar for tidying up, whether it's 30 minutes, two hours, or half a day, you create a firm intention in your mind.

This makes virtual cleaning easier and more efficient. Because let's face it: no one likes spending hours dusting...

What's more, regular sorting ensures you don't end up with a mountain of emails to deal with at the end of the day/week/month.

02Say Goodbye to Unnecessary Emails

Between you and me, do you really care about that newsletter on 1,000 ways to fold a napkin?

Not all the mail in your inbox is created equal. But a buildup of useless emails can lead to a cluttered inbox, putting you at risk of missing important messages.

So make your life easier by unsubscribing from newsletters and mailing lists that don't offer you much. Also, remember to check that your spam filters are active and ready to stop worthless emails.

We promise, no one will miss the swan-shaped napkin...

03Filter and Sort Your Emails by Category

Did you know? All email software worth its salt includes Outlook filters that automatically sort incoming emails.

You can activate filters based on the subject, certain keywords, or even the sender. These emails can then be sorted into different folders or categories.

Define the relevant filters according to how you use your email, then create email categories. For example: "Personal," "Professional," "E-shopping," or "Tableware newsletter."

This way, you can be sure you won't miss any important emails.

04Consider Setting Up an Automatic Reply

You are bound to find yourself away from the office from time to time, whether for a business trip or a vacation. During your absence, emails can pile up and all your hard work sorting them will need to be redone.

To keep your inbox tidy, use an automatic reply! A well-written out-of-office message will encourage your contacts not to spam you while you're on vacation or away.

It also shows your professionalism, letting people know that you're still there for them! Speaking of professional communication, don't forget to end your emails with a nice professional email signature.

05Clean Your Email Inbox Regularly

For balance in all areas of life, Marie Kondo (yes, we're big fans) recommends decluttering your closets, drawers, and (probably) your email inbox on a regular basis.

We couldn't agree more! Get into the habit of clearing out the different sections of your email inbox (inbox, sent, junk, etc.) of old emails to free up mental and virtual space.

You'll see your communications more clearly and attract positive energy and prosperity.

06Simplify Your Email Subject Lines

There's nothing like an effectively worded email subject line to save time! With a concise and explicit subject line, you won't waste precious minutes sorting through important emails and junk mail.

A simple email subject line makes it easier to categorize correspondence. It also makes it easier to find a specific message using search terms or email filters.

What's more, a well-written email subject line can significantly boost your email marketing strategy by making your recipient want to read your message.

And to further improve your communication (as if that were necessary!), use an email signature solution to add a professional, impactful signature.

07Create Email Management Rules

You don't trust machines and prefer to rely on your good old brain? Okay, we get it. It's true that a world ruled by robots isn't exactly our dream either.

But sometimes automation has its advantages! Email rules, for example, allow you to systematize certain tasks without having to think about them. This is a real asset, especially for keeping your emails organized.

You can define a rule to set up an automatic message, categorize your emails, or even automatically empty your inbox. It's just a little technological help; you're in control of everything else (for now...).

How Many Rules Are There in Outlook?

What Is the Maximum Space for Creating Rules?

First, it's important to know that Outlook does not impose a limit on the number of rules that can be created, meaning that you can configure as many rules as you want.

However, there is a space limit for the number of active rules. These are the rules that actually take up space in your Outlook mailbox. The amount of space used depends on the type of rule, its name, and its conditions.

You can activate as many rules as you want within the 256 KB limit, regardless of your version of Outlook.

How Many Types of Rules Are There in Outlook?

If by "How many rules are there in Outlook?" you mean the number of possible types of rules, there is no official list. Since rules consist of combinations of instructions, the number of possible combinations is at least in the tens!

These combinations can be categorized as follows:

  • Actions, to configure the specific action. For example: delete certain emails, sort emails according to a term or sender, or flag emails for follow-up.
  • Conditions, to determine specific conditions for applying action rules to certain senders or types of emails. For example, apply only in the case of a first email, or apply only if the email is encrypted
  • Exceptions, to not apply action rules based on certain factors. For example, do not apply to a specific sender or if the message comes from an external provider.

Unfortunately, it is not possible to create an email rule directly in the Outlook app, regardless of whether you have an Android or iPhone.

To do this, you must go through the Outlook website or Outlook 365, the desktop version of the email software. Create your rules on your computer or via your smartphone's browser by following the steps described above!

The same applies to other features, such as professional signatures. Here are the steps to add an email signature to Outlook.

Creating Outlook rules on Windows is the easiest and most intuitive process. This makes sense: Microsoft simplifies protocols for its products!

To create an Outlook email rule on Windows:

  1. Open the app
  2. Go to File in the top left corner
  3. Select Manage Rules and Alerts.
  4. A window will open; click on New Rule.

  9. Select Finish, then OK.

Please note! Some rules created in the desktop version of Outlook only work when Outlook is open: these are called local rules. If you need a rule to be active at all times, it is best to define server rules via the web settings.

On Mac, creating an Outlook rule is also quite simple:

  1. Go to the menu, then go to Message > Rules > Edit Rules.
  2. Select your account type (IMAP, POP, or Exchange).
