Podio & marketing Help pleaaaassssee!

[Casanova Brooks]

Hi all, my brain is completely fried. I'm a realtor and investor friendly agent. I've started using podio and created my own apps from scratch. I'm also using integrations with Globiflow and zapier. My question is, how do you all or can I, use Podio to manage all contacts for marketing? When I meet someone new who could be a potential client whether it be residential or investor should i be adding them to a certain group in my phone as well? 

I'm wanting to start a monthly newsletter and I'm looking to create automation so when I add them they are automatically added to my newsletter so that's a way I can stay in front of them because as we know, out of sight--out of mind. Does anyone have any solutions? It would be VERY much appreciated. Thanks!
