Geting started doubts metric tools, email and social media marketing

Hi All,

I am a solo tech founder. I am trying to bootstrap my own startup. Its basically a c2c hyper-local business. I have finished coding the entire app, and have asked few friends to beta test it. Modifying on what they are suggesting.

Tools I am using for gathering metrics : Google Analytics and Mixpanel free. Any other suggestion will be helpful.

I spent past week learning minimal SEO and have structured the html and other things are in place.

The next thing which comes is launch, for that I need to have social media and email marketing in place. I went through kissmetrics blog.

For email marketing I read http://www.eliteemail.com/learning-center/email-marketing-tips/ Further suggestions and few must haves will be appreciated. As in cheap tools etc.

I am trying to learn social media marketing and again it will be great if someone tells me the minmal effort that i should put, it will be really helpful.<p>Will be good, if people mentioned the tools they use to track their email and social media campaigns.

Thanks everyone!
