Fonts in Emails - Can I use other fonts?

Each email client (ie: Gmail, Hotmail, Outlook, Apple Mail etc..) will have its own set of fonts that it supports and it will display your campaign in the intended style if the font is compatible with that system. If your selected font is not compatible with that email client, it will be displayed via a fallback font style (or worse, unreadable characters). 

The fonts available for you to use in your campaign are known as Web/Email Safe Fonts. This is a list of fonts that the majority of devices and email clients support by default. 

Using a web-safe font in your campaign means that all your subscribers will see the text in the exact same way. 

Some of the popular web-safe fonts are Arial, Helvetica, Georgia, Verdana and Times New Roman. These typefaces also have great readability for desktop and mobile devices.

Simply put, you can't. Or rather, you shouldn't due to a lack of support. 

As the majority of email clients only have a specific list of supported fonts, using any other font in your campaign will result in the majority of your recipients not viewing your message in the intended style and will be forced to read it via their email client's fallback or may not be able to read your content at all. 

You should generally choose an email-safe font that matches your brand and identify. Generally, designers will provide a safe fallback font to be used in-place of the custom font within the brand guidelines of an organisation.
