Constant Contact - fact that you don't yet have the ability to add contact info (first names, cities etc) to your subject lines is enough for me to reconsider being a Constant Contact customer and take my business somewhere else. You're way behind your competitors, and this feature is extremely important to email open rate success. Please prioritize this - you can't possibly be 'thought leaders' on email when you don't even offer the basic functionality to improve open rates.
