How to Effectively Use Logos in Email Signatures

A company’s brand is its identifier; a logo can symbolize who a company is and what it does. That is why it needs to be used correctly in every form, whether that be business cards, letterheads or online presence.

However, one form that is often forgotten is corporate email, the most common business communication method. This can be damaging to a company’s brand reputation. This why it is important to include company logos in email signatures.

Every email an employee sends is an opportunity to raise brand awareness through the use of email signatures. By creating an email signature that includes your company logo, recipients are much more likely to remember your brand and company.

When a contact repeatedly sees your company logo in an email signature, they’ll recognize your brand. As a result, they will be more likely to reply to your message. This also creates a strong sense of trust.

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

So what is the best way to ensure HTML email signature designs include your company logo? What size should the logo be? Check out our tips below on how to implement email signature logos correctly.

Using certain types of logos in email signatures

If your logo features an icon and the company name alongside it, we recommend using the full logo on new messages. Then, when replying, only use the icon. You should also only use an icon image on internal emails.

However, if your logo has the company name is incorporated into the design, we recommend using it on both the main email signature and reply/internal signatures.

The ideal logo size

It is recommended that your email signature logo isn't more than 200px x 200px in size. This is so the logo doesn’t overpower other signature elements such as the contact information.

You also need to ensure the size of your logo doesn’t change in different email clients. This is why you should resize the image to the correct dimensions before you add it to your email signature design. Even if you have made the logo size smaller in the HTML code, some email clients will ignore this and revert the logo back to the original dimensions.

Inserting images into your email signature

If you use an embedded image as your email signature logo, there is a risk that it will appear as an attachment or not appear at all. Also, there are known issues with images being stripped out of emails and increasing in size on iOS devices.

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