# Email Marketing - Modifying fonts
To modify fonts in email marketing, follow the step-by-step instructions:
After opening your email builder tab, click on the **font field** you want to add:
Right after, click on '**Manual CSS**';
Then, enter the font code you want;
You can use the code format: **font-family: fontname;**
*The font-family property helps customize the style and appearance of text on a web page.*
After changing the font code in Manual CSS, your font will be modified!
