I am currently working on an artwork which I plan to use for an email blast and not for print. Since I am new with InDesign, I want to know if I need to flatten the fonts / transparencies like what I normally do in Illustrator.

I also started exploring InDesign and made the artwork somehow interactive. I have already saved it as an interactive PDF but I am not sure if the it will be affected once I upload online or send as an email.


If you are publishing your work as email, generally speaking, you have to roll back your ambition to the most basic HTML page, or even to putting in a simple PNG or JPEG bitmap of the entire document, perhaps with slices, depending on how complicated your design is. You also need a plain text version of your document for email readers that either don’t support HTML or have HTML turned off.

Interactive features are not supported by email clients. Maybe there is a little bit of CSS interactivity that can get through, but JavaScript is not going to happen. That would be a security risk.

A good idea is to pretend you are targeting a Web browser from 2005 with JavaScript turned off.

So you don’t do any flattening in your InDesign document, you flatten when you export to HTML or PNG or JPEG.

  • Just to extend this answer. Depending on what exactly you want to do, you may upload your pdf online and then send a link to it in your e-mail instead. Obviously you only want to do that if there is enough information justifying it. (its a guide or e-book etc.)

  • It is an advert type of document which needs to use links. I ended up using mailchimp since I do not have the luxury of time to code everything.
