Is there a place on Stack Exchange where I can ask the following:
Let's say your company sends its customers quotes. In the quote it has some fancy images, logos, and HTML/CSS to help sell the quote to the customer.
The problem: When you embed the HTML/CSS into an email, you are working at the mercy of the email provider to render the HTML/CSS correctly. First, different email providers will render your quote differently. Second, you have a subset of HTML/CSS to work with.
A workaround is to attach a PDF of the quote and also link the quote externally so a browser opens it. The body of the email may look like this:
Your quote is attached.
Additionally, you may click here to view your quote.
The question is, would there be a huge loss in views since people willing to open an attachment or click on an external link may be less? And where can I find data to support the conclusion?
