I have a service where I notify people of lectures. The best is when I can email the information. Some of the people would rather have it by text. Thinking about what I could do to break this 160 character limit barrier, I started using mypixmessages.com. I only send email messages like that if the people told me that their phone accepts pictures. I must have sent about 30 messages like that and then noticed in my spam folder about 30 messages.

Message could not be delivered to mobile.
Error: No valid recipients for this MM

What does this mean? Is there any better system of sending out text messages through email and breaking this 160 character barrier other than sending out the email in parts.

Thanx for all your help.
