Have two inputs a summary and a longer text field... kind of like an email subject.

Then limit the text input to like 100 chars, giving another 60 for general "... continued in email to you@..."

Send the summary as the subject, and the full text in the email. easy peasy.

I'd also add a simple text auth/password prompt as well as list the contacts and their respective email and phone numbers too, so you can call easier.
