Mailing List Problem

I’m in a band, and we routinely send out E-mails to a mailing list we collect to inform people of upcoming shows. The problem I’m having is that for some reason, the computer adds a back-slash (/) before any apostrophe or quotation marks in the mailing. For example, here’s what part of one of our old mailings looks like:

We’ll send out more details as the show-date approaches.

I’ve tried doing it in MSWord with and without the smart quotes on, and it doesn’t seem to matter. Any ideas???

Tell us what email program you’re using.

The name of the program is:
