You would like your emails to always be easy to read, but above all: your message must come across clearly. Therefore, we give you a few tips on using fonts and fonts in emails:

  1. Understand the difference between "safe fonts" and "web fonts"

  2. The general use of fonts in your e-mail

  3. The use of headings and sub-headings

Tip 1. Understand the difference between "safe fonts" and "web fonts"

When you start working with different fonts, it is important to know what safe fonts and web fonts are.

Safe Fonts

Safe fonts, or e-mail safe fonts, are fonts that display on any computer or device. Examples include:

  • Arial

  • Helvetica

  • Georgia

  • Times New Roman

  • Courier

Safe Fonts always display properly on any device when opening an email.

Web Fonts

Web fonts are fonts designed specifically for the Web. Web fonts were originally designed to be used exclusively on websites, so their licenses are usually only for use on websites and mobile applications.

Many e-mail services do not allow the use of Web fonts in e-mails because such use is considered distribution of the font. This violates the End-User License Agreement (EULA) of many services.

Is a Web font not supported by an e-mail service? Then your font is reset to a default font. This makes Web fonts less reliable than so-called safe fonts.

Each provider has a different license when it comes to fonts. This means that there is no standard way in which fonts are licensed in e-mail.

Web Fonts are fonts such as:

  • Open Sans

  • Roboto

  • Lato

  • Ludica Sans

  • Bitter

  • Droid Serif

  • Montserrat

  • Ubuntu

  • Karla

  • Bree Serif

  • Muli

  • Inter

  • Oswalt

  • Abril

  • Poppins

  • Heebo

  • Exo

  • Arimo

  • Saira

  • Raleway

  • Cinzel

  • Comfortaa

  • Bebas Neue

There are many more fonts. All Google Fonts are also Web Fonts.

Please note that every e-mail client has a different license as far as fonts are concerned. This means that there is no standard way fonts are licensed in emails.

Is the font not recognized? Then a default font displays.

Tip 2. General use of fonts in your e-mail

Your font has only one purpose: it must be clearly readable. Therefore, do not use too much bold, underlined or italicized text if it is not necessary. Your newsletter subscribers may find this irritating or awkward. We recommend the following:

  • Use no more than three different fonts in one email (preferably less)

  • Do not use more than two different colors in your text

  • Do not use too many 'fancy' fonts as titles, but use simple fonts. It should always remain readable.

Tip 3. The use of headings and sub-headings

What significantly increases the readability of your e-mail is a clear distinction between your headings (titles) and sub-headings (sub-titles) in your e-mail. Here are some tips:

  • Headings: Use headings to add structure to your e-mail. Be sure to use them consistently, for example, always twice the size of your regular text.

  • Links: Choose a color that matches your branding to make your links in your email stand out. Underlining links already happens automatically in our email editor.

  • Bold + italics: Use bold and italics sparingly and strategically. Does it make your point clearer? A good example of this:

In this example, you have a nice house style color for the button and introductory text. The title is highlighted large and bold. The title highlights a personal touch, namely 'yours'.
