The NiceSender email builder offers 11 default web-safe fonts for creating campaigns. However, you might find yourself needing a specific brand or designer font. The NiceSender editor disables custom font uploads to ensure maximum deliverability and compatibility across various email clients. We explained why this is the case in detail in this article.

Why Custom Fonts Can Cause Display Issues in Emails
When you design an email on your computer, you see all the embedded fonts. But the recipients of your email campaign will only see the fonts installed on their own devices. On most devices, custom or unusual fonts will not render correctly and will fall back to default system fonts. As a result, your design won’t look the way you originally intended.
2 Ways to Solve the Custom Font Display Problem in Campaigns
You can solve this issue in two ways:
- Use external fonts directly in the NiceSender HTML email editor. However, this requires a solid understanding of HTML coding nuances and thorough testing of your completed emails. Read more about this in our article.
- Convert your custom text/font into an image using a specialized tool or design software.
The rest of this article is dedicated to the second method.
How to Convert a Font into an Image and Add It to Your Campaign
When HTML coding isn’t an option for you and your custom font cannot be replaced with a standard one, you can use a text-to-image conversion tool.
The key is not to overdo it. If your entire email consists of images, spam filters will route it straight to the junk folder, and screen readers used by visually impaired subscribers won’t be able to read the text. A safe approach is to build the body text using a reliable web-safe font and reserve custom styling only for main headings or banners.
How to Convert Text into an Image Using a Free Website
You can convert your required text into an image using an online tool — here is how it looks on an example service:

NiceSender includes a built-in template testing feature before you send, allowing you to ensure your email renders correctly. You can check how the email will look across different major email providers (such as Gmail, Outlook 365) and on various devices.

For the most accurate preview, always send yourself a test email.
Despite the technical restrictions enforced by email clients, you can use more than just standard system fonts in your email marketing. You have two reliable methods to achieve this:
- Coding via the NiceSender HTML email editor.
- Converting your text into an image using a suitable editor or tool.
This ensures your message reaches your recipients exactly as you intended.
