I’ve found a nice HTML email template that I would like to customize and use to send automated emails to my clients. The template is MIT licensed, which means I should provide a copy of the license (or a link to the license) on all copies of the software that I distribute.
However: email HTML is often preprocessed by email clients (like Gmail) such that much of the original code is modified. For example, most email clients remove html comments and even parts of the code that are not visible.
I would like to use the HTML templates for my emails without putting something like “This email was created using library X, licensed under the MIT license that you can find at Y” at the bottom (I want to keep the email short and clean).
Would that be allowed? How can I include a MIT license “under the hood” in this situation, where the final code is preprocessed by email clients?
