How to choose the best email signature format

email signature format

When it comes to branding your business emails, the email signature format is an essential design point to consider. Having an email signature that has had no thought put into the layout can look messy and make you look unprofessional. 

If you’re struggling with getting your email signature format correct, check out our guide and a few email signature examples below. 

Choosing the correct email signature format hierarchy 

The best way to decide on the correct email signature format is by creating a signature hierarchy with the elements you want to include. 

First things first. If you haven’t already, decide on the elements you would like to include in your signature. Check out this article for help with what to include. 

Next, you’ll need to actually create the hierarchy. Simply put, create an order in which you want your contact information and other signature elements to appear. We typically suggest having your name and job title at the top of the signature. These are the most important parts of any email signature example and should always be front and center. 

The email disclaimer should be at the bottom of the signature. Although it is important to include, it’s not the first thing the email recipient should see: 

  • Full name 

  • Job title 

  • Company name (optional, if appears in logo)

  • Phone number (with country area code) 

  • Email address 

  • Website URL 

  • Company postal address 

Then come optional elements: 

  • Photo image 

Perfecting your email signature layout 

After you’ve decided on the order of the signature elements, you need to format the layout of the signature. When it comes to email signature formatting, a simple layout is always best. Having the company logo as the focal point is the best place to start. 

The shape of your logo will play an important part in your email signature formatting, whether it’s a square, rectangle or circle. Your logo should be the focal point of the signature, as including your brand is essential. 

Adding HTML tables to an email signature 

For the ideal email signature layout, we recommend using HTML tables where possible. HTML tables are the best way to build an email signature design. By using rows and columns, you’ll give the signature template an executive feel. 

You can use padding to create space between the individual design elements. This will be read universally by all email clients like Gmail, Outlook, Apple Mail and iOS. You can set a fixed width on any table to ensure the signature also fits on mobile devices. 

If you want to use a more complex email signature format, you can even add tables within tables depending on the design required. 

Correct image size in an Email signature example 

These are the recommended email signature formats for HTML images: 

  • JPG 

  • JPEG 

  • PNG 

  • GIF 

You can either host images on a website or embed them directly into your email signature template. Whichever option you choose, the images should be uploaded at the correct size. You should also include Alt Text for each image. This is in case they don't show up correctly when a recipient receives your email. 

If you aren’t using an email signature solution, images can appear as attachments if you embed them in a template. In this scenario, it’s better to use web hosted images. This way, the images are hosted on a public server and use hosted URLs to link into the email signature template. 

It's also recommended that you avoid using unique fonts, colors, and graphics in your design. These can make the signature format look cluttered.
