Finally I've got a feeling of what happens when a company is sending out an email campaign with a poor design. At least it should be one of the most important cases.
I've been reading through web designers CVs lately. A lot of CVs as I'm looking for an email designer for a top 3 Russian cell phone operator. And I see a situation when web design is being done by designers with a printed design experience.
At first they're starting doing things for web - and it's a mistake #1 as they don't fully understand that media. And at some point some person asks such a designer to create a mockup for an email campaign. But email as a channel is different even comparing to web design! And here we go - the designer who totally doesn't understand email marketing is guiding the way email are going to look like.
