Your email signature serves as a virtual business card, helping you leave a lasting impression with each message you send. 

While a well-crafted signature is essential, incorporating an image can take it to the next level, adding a personal touch that makes you memorable in a crowded inbox.

However, many people dread the process thinking they need advanced technical and design knowledge.

Although the latest digital solutions have automated the process of adding an image to an email signature, there are still a few things you should pay attention to.

Read on to learn about the hottest tips to add an image to an email signature.

Let’s dive in!

8 Reasons Why You Should Include an Image to Email Signature

Including an email signature can bring heaps of benefits, such as a dash of professionalism, info you can include, etc., but including an image elevates those benefits.

3. Visual Appeal

Having an image in your email signature can break up the monotony of text in an email signature, making it visually appealing and drawing attention to key information.

4. Recognition

Regardless of whether you include your photo or a logo, it can help contacts link a face with a name, and consequently raise brand awareness. 

5. Marketing and Promotion

In addition to raising brand awareness, an image as a part of an email signature can also boost your marketing efforts in a non-tacky or pushy way.

For example, you can include an image related to a promotion, event, or a new product.

6. Link to Professional Profiles

If the image is a headshot, linking it to your professional profiles can pique your contacts’ interest and encourage them to learn more about you and your professional background.

7. Differentiation

A visually appealing email signature can help your emails stand out and be more easily distinguishable from others.

This is particularly crucial if your recipients have an overcrowded inbox.

8. Mobile Recognition

A visual element like an image benefits mobile users since it makes your signature more noticeable and recognizable in the limited space on mobile devices. However, don’t forget to optimize your photo to make it mobile-phone friendly.

5 Tips to Add an Image to an Email Signature You Should Try Today

1. Choose The Best Image Size

signature-size-limit

1.1. A Profile Image Size

The most optimal image size is around 300-400 pixels in width and 70–100 pixels in height.

Furthermore, you also need to have mobile phones in mind since a majority of people use them to check their email. Thus, don’t go over 400 pixels.

1.2. A Logo Size

A rule of thumb is to save a logo picture at a resolution twice the intended display resolution.

Therefore, if you want your displayed logo to be 400 pixels, your actual logo must have 200 pixels.

1.3. A Banner Size

If you want to have a banner as your image, it shouldn’t exceed a width of 700 pixels and a height of 100 pixels.

2. Choose The Best File Size

The optimal file size should be less than 20kb because the “heavier” the mail, the more it will clutter the communication. 

In addition, large file sizes are most likely to trigger spam filters.

3. Select The Right Image File Format

JPG and PNG are the 2 most common file formats.


Qualities

JPG

PNG

Compression

Uses lossy compression, meaning some image quality is affected to achieve smaller file sizes.

Uses lossless compression, preserving the original image quality without sacrificing details. However, this often results in larger file sizes compared to JPEG.

Transparency

Doesn’t support transparency. 

The image background is always opaque.

Supports transparency, allowing for parts of the image to be transparent. This makes PNG a preferred format for images that require a transparent background.

Color Depth

Supports 24-bit color depth, making it suitable for photographs and images with gradients.

Supports both 8-bit and 24-bit color depths, making it ideal for images with transparency and sharp edges, such as logos and graphics.

Use Cases

Ideal for photographs and images with complex color gradients, where a slight loss in quality is acceptable to achieve smaller file sizes.

Ideal for images with transparency, logos, icons, and graphics where maintaining high quality and sharp edges is crucial.

Editing

Each time you edit and save a JPEG image, it undergoes compression, potentially leading to a cumulative loss of quality

Being lossless, PNG allows for multiple edits without any loss of quality, making it suitable for images that require frequent modifications.

Thus, you may generally choose JPG for photographs and situations where smaller file sizes are crucial.

On the other hand, you may select PNG for images requiring transparency, sharp edges, or lossless quality preservation.

Besides these 2 common file formats, GIFs have become popular, too. They can work great for logos or similar illustrations and can even be animated.

Although they do add to the visual appeal, be careful when using GIFs because they can quickly add up to the size of your email signature.

4. Decide Between Embedded and Hosted Images

"Embedded" and "hosted" refer to different approaches to including images in digital content.

4.1. Embedded Images

As the name suggests, embedded images are directly included within the content, whether it's an email, document, or web page. 

In other words, the image data is part of the file itself, so the recipient doesn't need to download additional files to view the images.

However, embedded images can increase the document's or email's overall size. In addition, they aren’t always mobile-friendly.

4.2 Hosted Images

Unlike embedded images, hosted images are stored on an external server or hosting platform, and you can reference the content using URLs.

Therefore, the image is not physically included in the document or email, meaning the size of the document or email is smaller.

Besides being smaller in size, an additional benefit of these image types is that they usually work on all platforms and are mobile-friendly.

 

5. Opt For An Email Signature Generator

Email signature generators are great helpers because they ensure that your contact information, formatting, and images are uniform across all communication channels.

Furthermore, they often provide customizable templates optimized for various devices and email clients.

As such, many email generators:

  • Create signatures with responsive design, meaning they adapt to different screen sizes.
  • Handle image optimization automatically so they may resize and compress images while maintaining visual quality.
  • Provide options to include necessary legal disclaimers or compliance information, helping you adhere to organizational policies and legal requirements.
  • Simplify the updating process by allowing you to make changes in the generator, automatically generating the updated signature for you.
  • Provide analytics features, allowing you to track how often recipients interact with your email signature. 

Email signature generators can save time, enhance consistency, and ensure your email signature reflects positively on your personal or professional brand.
