not spam - but poor practice

As this email has a postal address and opt-out included, I doubt it is spam. However, it does nothing to tempt me to click on the link to 'view my invitation'. Points to note:

• there is nothing to suggest what the invitation or offer is
• there are two email addresses for prof Kothari
• the sender couldn't be bothered to capitalize his/her name

all in all, a waste of time sending it out, I wonder what the open rate was?
Footnote: out of curiosity, I did click on the link - it was for some kind of personalized search engine. It looked a bit dodgy, so I did not click on the link that looked as though it might have downloaded something.
