We have an opt-in mailing list of over 90,000 customers that we segment and send promo emails to occasionally. I use WWIPStuff from West Wind. I can get it to send HTML email, I can get it to send text email, but does anyone know a way (either with WWIPStuff or not) to send it as both, so if the recipient doesn't have an HTML capable email client they will get the text version?

TIA!
