So essentially what we have is a 1% unsubscribe rate for an e-mail, which is above his .5% average but it's still within the range of error and many things could effect the unsubs except the email content. Maybe his e-mail list is growing and after getting a few e-mails people realize that this isn't what they expected. Or the expectations they had for the content weren't set properly. Saying that funny/longform e-mail is that what caused the sudden unsub spike is jumping to conclusions.
