#Nancy Oshea, You nailed it on the head, rep's responsibility is to sell, and majority of them won't have any web knowledge, asking every single one of them to sign up to mailchimp, load cvs, learn to work mailchimp, migrate original html from outlook to mailchimp would be a tall task. It wouldn't be fair to them as this should be design/market team's job, not sales dept's. Why do we let reps send out emails? To let reps send out eDMs is more targeted than to send from corporate.
Another scenerio is we send the eDM to PMs, PM sent to reps, and reps to clients. Again, PM's job are engineering/development of products. Not feasible nor in company's interest to have hundreds of PMs and sales to signup/learn mailchimp.
It could possibly be more efficient to use PDFs instead of html emails in this situation, especially if the design elements of the document are an important factor.
Since the recipients expect to receive the email, there wouldn't be much issue with the "don't open attachments from people you don't know" advice, and a PDF attachment would be rendered fairly universally, either through browsers and email clients with native support, or through Acrobat.
It would also be relatively small, if it's just mimicking an html email.
