Thanks for the feedback! If the recipient's user agent doesn't display images we don't record an impression, and so it doesn't show up in the analytics.

I totally understand that it might be annoying to only get a marketing message from clicking "Display Images". I guess the way I look at it is that it's a chance for companies you're already interacting with to tell you things about themselves that you might not already know - so it might be annoying or if you like the company it might be cool too.

It's also an amazing platform for organizations like schools, charities and political campaigns to do outreach with. For example, a charity can have their big donors install this in their signature and have a unified, centrally controlled donation message going out every day that's always current and updated.

Thanks again for the feedback!
