How to effectively use logos in email signatures

A company’s brand is its main identifier. Its logo is the main visual element that symbolizes who the organization is and what it does. However, one channel where branding is often forgotten is corporate email, the most common business communication method. This is why a company logo in email signatures must be added to every business email. 

Every email employees send is an opportunity to raise your brand awareness and increase stakeholder advocacy. By including a company logo in emails signatures, each email will show professionalism, and your recipients are more likely to remember your brand. 

As a contact repeatedly sees your company logo within the email signature, brand recognition becomes second nature. So, they’ll more likely trust your brand and listen to what you have to say. 

Corporate logos in email signatures also add extra professionalism to email communications. Think of an email signature as a digital business card. It must be well-designed, conform to brand guidelines, and provide important contact information. When designed well, an email signature will actively promote your company’s brand in a positive and professional manner. 

Check out these top tips on how to implement email signature logos correctly. 

Using certain types of logos in email signatures 

If your logo features an icon with the company name alongside it, the full logo should only appear in email signatures used for new messages. Then, when replying, only include the icon along with a simpler signature design.  

We recommend only using an icon image on internal emails too. Employees already know your company name after all. 

However, if your logo has the company name incorporated into the design, we recommend using it consistently within your main email signature template, replies and internal signatures. You don’t want to change how your logo looks so it’s inconsistent with how it appears on other channels. 

Choosing the ideal logo size 

We recommend that your email signature logo size is no more than 200px x 200px. This is so the logo doesn’t overpower other elements like contact information. 

You also need to ensure the logo won’t change in size in different email clients. So, always resize the image before you incorporate it into your email signature design. Even if you make the logo size fairly small within your HTML code, some email clients will ignore this and revert the logo back to its original dimensions. 

Inserting images into your email signature 

If you embed your email signature logo, you risk the image appearing either as an attachment or not at all. Also, there are known issues with iOS devices stripping images out of emails and increasing the overall file size. 

To avoid this, ensure all images are hosted in a publicly accessible online location. This way, you simply include a link to the image within the email signature template.
