Best CRM software for off market deal finding?

[John D.]

Does anyone have any recommendations for a CRM to use for managing leads from off-market deal finding? I am hoping to begin marketing with direct mail, cold calling, FB ads and Google Adwords (driving to my website) but I am trying to figure out the best CRM to use which is not extremely difficult to set up, but still offers decent flexibility for how it can be configured for RE investors. Ideally some  integrations with tools like Zapier, etc. would be great. 

I have heard that Podio is great, and super flexible, but can be a bit of a beast to set up initially. Does anyone have any other recommendations?
