Vertical Response wows us again. Just saw this note in their newsletter, explaining how Word can cause formatting problems, like inserting a ? where an ' is supposed to go. If you didn't know that, now you do. If you paste copy from a Word document, or from copy you were sent in an email, there is code behind the lines that you can't see. When it's from Word, it sometimes inserts strange symbols and often messes up the apostrophe and the quotation mark.
When you are creating an email in Vertical Response, and if you only have Word to work with, you can insert your copy and press a button to clean it up. This little button cleans your copy, and you've got safe content to work with that won't turn into gobbledegook.
Get the details here:
If you're on a Mac, you can paste your copy into TextEdit, which also leaves clean content (but doesn't resolve all spacing issues if something is weirdly spaced). Windows people can use Notepad.
