I find it hard to send an email to say 10 companies if most of them don't have a contact email address and use Form2mail.
If you have had any prior e-mail contact with a company, you know their address and possibly even the name of an individual human to go with it. Under what circumstances would you need to send identical (I assume) emails to ten companies that you've never communicated with before?
