For my experience (7 years now), this is effectively so, you do not need a CRM at all. Your inbox with a folder for each customer/contact/project is your best CRM feature. The only thing I have at a "large number" level is a very stupid web application storing just 2 things: an email address and a corresponding full address like you print on the envelope. Then every year, I can send 125+ new year cards. I take the time to include a nice design for the card, people enjoy them and this is a nice way to keep in contact with a large number of people.
