Do you have a beautiful company logo, but feel extremely sad when you realize that it isn't seen enough?

Don't worry, we've all been there! (No? No!... OK, maybe it's just me...)

What better way to give your logo more visibility than to insert it directly into your company email signature?

Here's our guide to adding a logo to an email signature! Let's get started!

Create Your Logo

Create email signature logo

Before you even think about inserting your logo into an email signature, you need... a logo (yes, logical). If you have one, great! You can move on to the next step!

If you don't have one yet, here are your options:

  • Hire a graphic designer: a simple solution with professional results, but it can be expensive.
  • Use an online logo creator: Canva, Looka, Wix Logo Maker, etc. These tools allow you to quickly generate a simple, professional logo.
  • Ask artificial intelligence: nowadays, a well-crafted prompt can enable most AI to generate high-quality images. So ask Chat GPT, Mistral, Lama, or Claude to try their hand at creating your company logo.

How Do I Add a Logo to My Email Signature?

01Professional Email Signature Solution

This is the simplest option! Companies that choose an email signature solution usually have access to a designer (this is the case with Letsignit) who can easily integrate a logo.

Simply add the logo to your signature template, and you're done! The logo is then automatically added to the signatures of all company employees.

02HTML Signature

If you're the type who likes to code in the dark, day and night, and are passionate about scrolling through lines of code on your 28-inch ultrawide hacker screen (sorry for the big cliché), then this option is for you!

You can create your own HTML signature from scratch or use an HTML signature template and customize it to your liking.

The advantage of HTML signatures is that they are fully customizable. You can choose the font, colors, add links, etc. And in the same way, you can integrate your logo wherever you want and make it any size you want.

All you need to do is take your signature code, for example:

<div>
<p>Company name</p>
<p>Employee name | Job title</p>
<p>Phone number</p>
<a href="website link">Website</a>
</div> 

And insert your logo code where you want it (<img src="URL-of-your-logo">). And if you want, why not add a link to your website (<a href="https://your-website.com">).

The final result:

<div>
<p>Company name</p>
<p>Employee name | Job title</p>
<p>Phone number</p>
<a href="website link">Website</a>
<!-- Add your logo here -->
<a href="https://your-website.com"><img src="URL-of-your-logo"></a>
</div> 

To ensure that your logo displays correctly, remember to host it on a reliable server where you can retrieve the URL.

03Signature Generator/Signature Creator

Don't want to code your entire signature in HTML? Let's be honest, there are much easier (and more modern) solutions. If you're not in a business that would benefit from a more comprehensive email signature solution (such as a very small business), then an email signature generator could be just what you need.

Ideal for smaller businesses and freelancers, a signature generator allows you to generate an email signature in image format or as HTML code to copy and paste. All this with a simple, user-friendly interface!

Here are a few examples:

Just try out the different options and choose the one that suits you best.

Once you've created your signature and added your logo, all you have to do is copy it to your email platform!

How Do I Add a Logo to My Gmail Signature?

Adding a logo to your Gmail signature is straightforward. Here's how to insert logo in Gmail signature:

  1. Open Gmail and click on the Settings gear icon
  2. Select "See all settings"
  3. Scroll down to the "Signature" section
  4. Click on "Create new" or edit an existing signature
  5. In the signature editor, click on the image icon
  6. Choose "Upload" to add your logo from your computer, or "Web Address (URL)" if your logo is hosted online
  7. Adjust the size and alignment as needed
  8. Save your changes

Your Gmail signature will now display your logo in all outgoing emails!

How Do I Add a Logo to My Outlook Email Signature?

To add picture to signature Outlook, follow these steps:

  1. Open Outlook and go to File > Options > Mail
  2. Under "Compose messages," click on "Signatures"
  3. Select the signature you want to edit or create a new one
  4. In the signature editor, place your cursor where you want the logo
  5. Click on the "Picture" icon in the toolbar
  6. Browse and select your logo file from your computer
  7. Adjust the size and positioning as needed
  8. Click "OK" to save your signature

Your Outlook signature will now include your logo for all new emails and replies. We've also written an article centered on adding images to an Outlook signature, if you're interested!

How Do I Add an Image or Picture to My Email Signature?

Photo in email signature

The process to add image to email signature is similar across most email clients:

  • Prepare your image: Ensure it's optimized for email (under 150KB, PNG or JPEG format)
  • Access signature settings: Go to your email client's signature section
  • Use the image tool: Look for an image/picture icon in the signature editor
  • Upload or link: Either upload from your device or use a web URL
  • Adjust and save: Resize as needed and save your signature

This method works for adding any picture to your email signature, whether it's a logo, headshot, or brand image.

What Logo Format Should You Use for Your Email Signature?

We also have an article dedicated to the format of your email signature (what a productive team we have!). The general idea is as follows:

Don't exceed 400 pixels in width by 150 pixels in height. This includes your logo, your profile photo (and your contact information, links, etc.).

And what file type should you use for a logo?

  • PNG: good quality and ideal for transparency. Be careful, though, as .png files tend to be larger than their .jpg counterparts.
  • JPEG: much smaller file, but does not allow you to create a transparent background. It all depends on the type of logo you want to use.
  • SVG: ultra-clear, but not always supported by all email clients. So this format is best avoided for the time being.

Incorporate Your Logo as an Email Banner

Email banners are commonly used to communicate additional messages (promotional messages, event invitations, communication about new content launches, etc.).

However, if you wish, you can also integrate your logo under your signature, like an email banner. There's nothing stopping you from integrating your logo on its own or creating a more comprehensive banner that includes your logo as well as several other elements of your brand.

In fact, the possibilities are as endless as your creativity!

How Do You Make a Logo Clickable in an Email Signature?

It all depends on the method used to create your email signature. If you have access to the HTML code for your signature, simply add a tag around your image.

For example, surround your logo with an ahref tag in the HTML code.

This will give you:

<a href="https://votre-site.com"><img src="photo-de-profil.jpg"></a> 

If your signature was created in image format, you can instead integrate the whole thing into your email platform and add a location via the text editor.

Have you used a signature generator or a professional email signature solution? If so, the tool was probably designed to allow you to add links to the desired elements. All you need to do is log back into the tool you used and use the feature provided for this purpose.

Result: an email signature logo that links directly to your website. Practical and professional! Wow!

That's it for this guide. I sincerely hope it has given you a little help in integrating your logo and that your professional signature is now looking great.

See you soon for more tips!

There are several options for inserting your logo into an email signature (as we saw in this article). However, if you want to use the simplest method (for a more limited result), simply go to your email settings (Outlook, Gmail, etc.), create or edit your existing signature, then import your logo image using the built-in editor. The image can be imported from your computer or via a URL if it is hosted online. Once inserted, you can even make your logo clickable: it will then redirect your recipients to your website or LinkedIn page.
