Salesforce Foundation

The Salesforce Foundation gives away 1% of the products, time and money of Salesforce.  What is Salesforce? It's open source and allows businesses to manage contacts.  Nonprofits can manage mailing lists, donor contact lists, grant lists, track funding and so much more.  If you aren't chosen to receive Salesforce for free, as a nonprofit you can continuously renew your 30 day trial for free (don't say it). It more than rivals Constant Contact and has great support.
