Biggest thing I took away from this is organize your contacts from the very beginning of starting your business so you can easily turn them in to mailing lists. There are so many different types of people I've talked to over the years of running my business: investors, experts in various topics, journalists, executives and it would be so nice when we have something to put out to just be able to refer to those various lists vs. digging through email and inevitably only finding a subset of those people.
