When designing an email, several layouts can be created by combining icons or small images, often with some copy. Other designs may require a set of images (logos) without the constrictions of row structures.
Here are a few layout examples created with the Icons block to give you an idea of how it can be used:
Example 1: Properties and Star Ratings
Example 2: Logos
Example 3: Bullet List
Here is how to use Icons in your email.
