3. Add to the file src to your server with the necessary font in the format woff2 (the script in this format would be in the kit), for example:

@font-face {
font-family: 'Spartan';
font-style: normal;
font-weight: 200;
font-display: swap;
src: url(https://fonts.gstatic.com/s/manrope/v1/xn7gYHE41ni1AdIRggOxSuXd.woff2) format('woff2');
unicode-range: U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116; 

4. Upload the file stylesheet.css to your server.

5. While adding the font to the editor, specify the file URL and family name, for example:

The procedure for adding fonts from other sources is the same; the only differences may be in the interface outlook.

Important Notes

1. If the font isn’t displayed in the email, check whether the device you’re using for preview supports custom fonts. Custom fonts that aren’t supported by the current email client are replaced by standard fonts.

2. Some fonts are only supported for languages that use the Latin alphabet and can’t be used for languages that use the Cyrillic alphabet.

3. The custom font is only applied to the email body: text copy, headings, subheadings, links. The email subject line and preheader will be displayed in a standard font determined by the email client.

Email example with custom fonts

4. For a proper display, do not use different fonts and different sizes of one font within one design layout structure.

5. When using a custom font, think how it would look in email clients that don't support it. The text with the replaced standard font may get bigger in size which may distort the layout. To avoid it, test the email, configure an alternative family, size and spacing for a correct display.
