Is your chosen font web safe and available for use? – Exclaimer Cloud Knowledge Base

Scenario

You are unsure whether the font you have chosen for your signature template design is web safe and available for use in your Exclaimer Signature solution.

NOTE: A web safe font is a font that is installed across all operating systems. If your chosen font is not installed on the recipient's PC, they will not see the font as you intended when you created your signature design.

Resolution

If your chosen font is not available across all operating systems, you can create a font stack with a list of fallback fonts.

NOTES:

- Font stacks control how the font will appear to the recipient if they do not have access to your chosen font.

- Fallback fonts allow you to specify web safe alternatives to fall back on if needed. This allows you to control how the signature appears across all devices, as you can choose the most similar fallback font to your original font.

The table below displays a list of the most commonly used fonts against the devices and operating systems they are available on:

	Windows	iOS	iOS13	Android
Arial	✔	✔	✔	✔
Arial Black	✔	✔	×	×
Calibri	✔	×	×	×
Century Gothic	✔	×	×	×
Comic Sans MS	✔	×	×	✔
Courier New	✔	✔	✔	✔

Impact	✔	×	×
Tahoma	✔	×	×	✔
Times New Roman	✔	✔	✔	✔
Trebuchet MS	✔	✔	✔	×
Verdana	✔	✔	✔	×

Example of a fallback string:

Calibri, Candara, Segoe, Segoe UI, Optima, Arial, Sans-Serif

In this example, the initial font type is Calibri. If Calibri is not available to use, it will move onto Candara until it reaches the "Sans-serif" font type.

CAUTION! Due to the behaviour being out of our control, the Outlook client will use the first font (specified in the font stack) and remove the remaining fonts (specified in the font stack) from the HTML coding.
We recommend you use font stacks for server-side signatures only.
