Email signature fonts

Every element of an email signature’s design is important, but getting the design right can be hard. One element that can easily ruin the design of an email signature is the font – not only the style of font you use, but the type of font.

It’s important to be careful with the types of fonts you use in an email signature. Believe it or not, using certain fonts in an email signature can break it, that’s because some fonts aren’t compatible on all devices and end up reverting to a default font.

What fonts can you use in an email signature?

Web safe fonts

Using a web safe font in an email signature will almost always guarantee the font appears on the recipient’s end as intended. So, what is a web safe font?

A web safe font is one that is installed on almost every Windows and Mac device by default, which means that if you use it in an email signature, it will look the same on the recipient’s end.

Here’s a list of recommended web safe fonts you can use in email signatures:

  • Arial
  • Calibri
  • Courier New
  • Verdana
  • Georgia
  • Trebuchet
  • Helvetica

Custom fonts

Custom fonts, such as fonts created specifically for a company, can be used in email signatures. However, as a custom font is most likely not installed on an external recipient’s device, the font may not to show correctly on your email signature and a fall back font, such as Times New Roman, will be used.

It is possible to set the default fall back font to one of your choosing, however, you’ll need to have good knowledge of HTML coding.


Email signature font style

Not only does the type of font you use in an email signature matter, but so does the style of the font; your email signature font could damage your brand’s reputation.

Using a garish or wacky font in a corporate email signature, such as in the examples below, is not recommended as this can come across as unprofessional.
