How Do I Create a Filter in Gmail?

Do you dream of a world where your emails sort themselves, where your important correspondence is immediately accessible, and where spam is nothing more than a bad memory? That world is possible, thanks to Gmail filters!

Whether you want to intercept advertising emails or organize your emails into the right categories, these simple settings will make your life easier.

Here is our complete guide to creating Gmail filters, your best allies for boosting your productivity and streamlining your correspondence.

What Is a Gmail Filter?

A filter, also known as a rule in other email software, is a setting that automates various actions for managing incoming emails, such as deleting or categorizing them according to different criteria.

Many actions can be automated using Google filters, such as:

  • Archiving non-urgent emails;
  • Deleting unwanted emails or spam;
  • Assigning labels according to certain criteria to facilitate categorization;
  • Automatically forwarding emails to other email addresses;
  • Marking important emails or adding stars.

5 Advantages of Gmail Filters

Gmail filters advantages

Gmail filters: they take 5 minutes to set up and save you hours of time. And that's not all! Here are 5 good reasons to set them up in your Gmail inbox.

01Effective Management of Your Emails

With Gmail filters, you can automatically categorize your emails according to various criteria, such as the sender or certain keywords. This makes it easier to search and process your correspondence according to priority.

Archiving and deletion filters reduce clutter in your Gmail inbox, reserving space for essential correspondence.

Finally, with forwarding filters, you can immediately include your colleagues and teams in correspondence of your choice, for example based on the subject, sender, or specific terms in the body of the email.

In short, these small adjustments will help you work more efficiently! Here's an extra tip for better email management: consider creating Gmail aliases.

02Better Visibility

By setting up sorting filters, you ensure better visibility of your important correspondence.

First, the "noise" of repetitive emails (such as newsletters) and superfluous emails (such as advertisements) is reduced. These are automatically deleted or blocked when they enter your inbox.

Labels, those small customizable and colorful tags, allow you to classify your emails by theme (for example: "Customers," "Team," or "Follow-up"). This gives you a clearer view of your correspondence.

Finally, because you can never be too organized, you can also configure the sorting of incoming emails into different folders in your inbox, such as the main folder, promotions, or social networks. Here again, there are many possible sorting criteria, such as the sender, specific terms in the email subject line, or even the size of the email.

This improved visibility ensures that you never miss an important email, whether it's customer feedback or an announcement about your favorite artist's next concert!

03Improved Security

Certain filters can be specifically configured to identify advertising emails and other spam, or to block suspicious senders, which improves security.

Once identified, these messages are automatically deleted or sent straight to the junk folder.

This gives you better protection against phishing attempts, scams, and dangerous links.

Your personal data is also less likely to be compromised by emails containing trackers.

An important criterion for your professional email inbox: your company's sensitive data deserves the best protection! In fact, to ensure that your important information is preserved, it's also good to know how to save an email.

04Save Time and Energy

As you can see, thanks to the power of filters, you spend less time managing and searching for your emails by significantly reducing manual operations.

Filters allow you to automate repetitive tasks such as archiving, transferring, or filing correspondence. You save precious minutes in your workday and have more energy to devote to more important or urgent tasks.

Not to mention a significant reduction in the stress associated with a disorganized inbox and increased reading comfort thanks to better visibility.

Want to save even more time when writing your professional messages? Here are some professional email examples and best practices to overcome writer's block.

05Better Email Tracking

With labels and filters, you can more easily identify important exchanges and never miss a reply. This reduces the risk of forgotten or unprocessed emails!

What's more, thanks to customizable filters, you can organize your follow-up according to topics, clients or colleagues, or specific subjects.

The result: more efficient and accurate management of your correspondence, ensuring customer satisfaction and fruitful exchanges with your colleagues. Speaking of professional communication, find out how to write a professional email!

Create a Gmail Filter in Gmail Settings

The most logical and comprehensive method for setting up your Gmail filters is to go through... the settings! This technique gives you access to all available criteria (sender, keywords, subject, age and size of the email, etc.), allowing you to configure complex filters.

To create a Gmail filter from the settings:

Here's how to do it:

  1. In Gmail, click on the search bar at the top of the window.

Questions
Fréquentes

1

Is it possible to track the number of clicks on email signatures?

Yes, with the 'Campaigns' offer, it is possible to track the number of clicks on the email signatures of all your employees in the 'Statistics' area of the platform.

You can then access a detailed or global view of the number of clicks on the email signatures of each employee. You can use the search option to target a specific signature or a given period. Finally, you have the possibility to export all statistics to an Excel document.

If you launch campaigns with banners inserted in your email signatures, you can also access their performance via this same space.

2

Can we add links to social networks, our website, and appointment-setting applications such as Calendly?

With Letsignit, you can easily add social network icons in your collaborators' email signatures and link to your company pages. Also, our "attributes" feature allows you to manage personalized URLs for each of your collaborators such as their individual LinkedIn profile.

And that's not all: you can add links to an appointment-setting application, allow your customers to leave reviews easily, and integrate our 'Chat on Teams' widget to let anyone start a discussion via Microsoft Teams chat.

3

Can employees update their signature information themselves (number, function, etc.)?

It’s up to you! As an administrator of the Letsignit platform, you choose whether or not to grant modification rights to your employees. These permissions are managed on an attribute-by-attribute basis, which means that you can decide to allow the employee to change their phone number, but not the address of your premises, for example.

This feature applies to all attributes in your directory, including custom attributes created on Letsignit. When your employees change one or more attributes, your directory is obviously not affected.

4

Why it is important to standardize our email signatures on a large scale to ensure our identity and brand image?

It often happens that employees make their email signature their own: custom format, bad fonts, colors inconsistent with the brand standards... all of this has an impact on your brand!

A consistent visual identity is considered authentic and outperforms a perceived weak one by 20%. And, your customers are 2.4 times more likely to buy your products.

With Letsignit, take back control over your brand identity by standardizing all your email signatures. Our tool has many features that allow you to customize your signatures by department, by audience or by subsidiary. Not to mention the possibility of carrying out campaigns within your email signatures thanks to our Campaign offer.

5

What is the user experience like for our employees?

What is the user experience like for our employees?

  • If you opt for the Letsignit Add-in for Outlook, they will have a dedicated space in their Outlook account where they will be able to view the signatures and campaigns assigned to them.
  • If you opt for the Letsignit Desktop APP, they will be able to preview all their signatures and campaigns in this space. If they want to change their default signature to another one when sending an email, this will be done in their signature library in Outlook.

In both cases:

  • They preview their signature before sending an email and choose from signatures assigned to them.
  • Based on the permissions granted, they will also be able to modify their personal information such as their name, position, or address in these spaces.

In short, they have autonomy in their email signature, but you keep control on the field, signatures, and banners they can edit or use.

6

Can my employees have multiple signatures available to them?

With our "multi-signature" feature, your employees can benefit from multiple email signatures. No technical manipulation is required. Thanks to our Add-in for Outlook or the desktop app, they can change their email signatures as they wish with just a few clicks.

Regarding the creation of email signatures, you can make several variations such as:

Everything has been thought of to go further in the personalization process based on the recipient of your emails.

7

Regarding “Green IT,” have you implemented measures to limit the digital footprint of email signatures?

If sending emails has an impact, non-optimized email signatures also have an impact. An unsuitable format or an image that is too heavy considerably increases the size of your signatures... and therefore, your emails.

As a responsible economic actor, we contribute to reducing our CO2 emissions and those of our customers in several ways:

  • Optimization of the weight of signatures and campaigns in emails.
  • Green features: lightening of signatures during response/transfer emails, possibility of not embedding images, implementation of lighter signatures for internal exchanges.
  • Integration of a 'Switch to Teams' widget to encourage your employees to continue their exchanges via chat, rather than email.

As we are increasingly involved in sustainability initiatives, our priority in 2023 is to develop even more green IT functionality.
