At the Email Insider Summit panel entitled "25 Trends In 25 Minutes," AlchemyWorx's Dela Quist says email marketers should monitor the specific days where people "unsubscribe" the most. Quist says generally it's Monday, when people are bummed because the week has started and use unsubscribing  to email list to express their anger.

StrongMail's David Atlas says a strategy that can work in emails is to show visitors what "platinum" customers can benefit from, say in a loyalty program, and that might persuade them to look to join.

Trendline Interactive's Andrew Kordek offered up a CURVE maxim for subject lines and said use at least two of these five concepts in them: curiosty, urgency, relevance, value, emotion.

Quist says don't call people who don't open emails "inactives," call them "prospects." Don't give up on them.

Atlas says marketers might try sending someone who has responded to a social promotion an email asking them to pass a message on to three people and in exchange offer the influencer a deal.
