Secure fonts for Email and Web

In your Email campaigns, the font you use can determine how users and customers perceive your company.

Details such as the design or size of the font can favour or hinder communication with your customers.

When viewing the newsletter, the text should have clear and well-defined letters, without resembling others, to ensure objective and uncomplicated reading.

Email-safe fonts

Safe fonts for Email and Web are styles that are easy to read and digitise, and convey the same appearance across all major Email providers.

To capture users' attention in a few seconds, and encourage them to continue reading the content, opt for text styles that reinforce the brand identity and are in line with the rest of the campaign elements, such as the design and inserted images.

There are two main font styles: serif (such as Times New Roman and Georgia) and sans serif (such as Arial and Helvetica).

Examples of secure sources for Email

Some of the most widely used and effective safe fonts for Email campaigns include:

• Arial - with a modern, elegant and simple appearance, it offers excellent readability without conveying a rigid, overly formal image.

• Helvetica - available on most Email systems and providers, it is ideal for capturing the attention of your audience, especially in headlines and subheads.

• Times New Roman - recommended for formal communications thanks to its classic, narrow and elegant design, although it can make reading more dense when placed in large blocks of text.

• Georgia - often used in printed materials, it has a professional image and provides good readability in a digital context.

• Tahoma - widely used in digital communications, it adapts to small spaces without compromising clarity.

• Verdana - with a simple, bold design and lines, it is one of the most widely used fonts for Email texts due to its excellent legibility.

• Courier/Courier New - similar to the style of old typewriters, it is usually used in technical reports, catalogues or other more specific content.

• Trebuchet MS - developed by Microsoft, this font is easy to digitise and read, even at small sizes.

• Geneva - similar to Helvetica, it is also a safe and compatible choice for Email.

Font size

In addition to the choice of font, the size of the text should also be considered. It should be neither too small nor too large.

The size of the font influences the prominence of the different parts of the content, such as headings and subheadings, making the information clearer and more visually objective.

The body of the text should ideally be between 10 and 14 pixels, and even in cases where a smaller font size is chosen, the text should remain completely legible.

We always recommend carrying out test sends to confirm that the campaign is legible before sending it to the entire audience.

The choice of font is a strategic decision that has a direct impact on brand image, communication effectiveness and user engagement.

By opting for Email-safe fonts that are easy to read and compatible with different service providers, you can guarantee more professional, efficient and accessible communication.

A well-chosen text style can turn a simple Email into a conversion.
