CRM vs Excel vs other for Contact Management

[Jonathan Orr]

Hi Everyone.  I have been getting some new contacts and have had the thought of having a better organization method for these new contacts as I may one day want to reach out to them about possible investing or something else.  I am not a realtor so I am not sales oriented, however I want a method to compile a list of "investor" contacts that I could maybe send out emails in mass or something.  Not really sure as I am just playing out with this idea and the tech is out of my wheel house. 

Anyone have tips or ideas?  Would prefer to not spend a ton of money on something I am just going to keep some contact in if possible.  Thanks.
