Just had an email where the client put his business card as the signature. As the vendor I frequently copy into an excel file the customers signature. That is much easier to do if it is text than an image.
For those of you that use images for your signature, I wouldn't or at least would augment it with the contact info in text.
The business card in your email might be a good idea though. You could probably put a print business card link in the email. Never tried it, so I don't know how difficult it would be. Some people probably still collect business cards. I don't but it's an idea??
