How to stop styling being stripped from email templates

What full version are you on? 10.X.x.xxxx

10.3.0.6491

bump!

The issue is that email templates can be still be subject to global filtering and client filtering.  We made slight improvements in 11 for this, but at the end of the day using a web based editor still means it can make adjustments.   To get those changes you need to upgrade to 11+ but still may not be able to do much robust markup and styles in emails.

Thanks Patrick, and dammit! I was hoping there was some way to edit the global filtering so as to allow specifically defined styles like max-width. I seem to remember I had that in 2008. Without it, I so far cannot find another way to make images render properly for retina screens. So emails created with an image in Telligent look bad on pretty much every ipad these days. 

OMG - I thought I had a next best thing work around, which was to create another version of the graphic, but this time setting an image as the <background> in a table cell, and overlaying text, which would mean at least my text would be sharp on a retina screen.

But no ... it strips the background attribute too. 

This is frustrating. I cannot for the life of me think of the rationale for stripping max-width or background. I wonder if there is a list of attributes you CAN use, because it is taking up a lot of my time experimenting!

Just in case anyone is following the rant I'm having with myself ... and might find this work around useful, the code stripper is letting me get away with: style="background-image: url('domainwithwwwsremoved/.../background-600.jpg'); background-repeat: no-repeat; background-size: cover;" Doesn't get round the retina issue, but it does allow me to add a background image which will be a bit blurry on retina screens, but I've added overlaying html text which will look sharp.
