Note: Keep in mind that your email may show some minor differences from the template created, depending on the platform or software used by the recipient of your email.

My software is not in the list!

This probably means that our templates have not been tested on it. They may still work, but we can not guarantee it.
Some software were deliberately left out either because they represent a very small proportion of users or because their support in HTML emails is considered too limited.
