They should, but they don't. That's the problem.

Every time I get a crappy text version of an email, I try to contact the company (via email or Twitter) to get them to care about text emails. Usually, I've received encouraging replies. It seems like marketing email services don't optimise text versions and companies don't even realise that. Probably because fewer people care about text versions.

I encourage you too, to send requests for better text emails if you care about this.
