According to a recent Email Marketing Metrics report by MailerMailer, open and click-through rates are influenced by the industry of the sender and the size of their lists. Generally, smaller list sizes yield better open and click-through rates.

“…Messages delivered to small and medium lists had higher open and click-through rates than messages delivered to lists of 1,000 or more subscribers. Religious and spiritual organizations had the highest open rates among large lists, followed by telecommunications and travel companies…” click here (no pun intended) to keep reading

Of course, this doesn’t  mean that you have to sacrifice open and click-through rates if you want to communicate with a large list of subscribers. It means that if you have a large list, it should be opt-in and targeted to the greatest degree possible. The fact that smaller lists yields better results has more to do with the fact that those small lists are generally compiled in-house and sent to recipients who consider the message to be highly relevant to them.
