Form data push to 3 places: Constant Contact, MySql, Salesforce?

Hi there - I have a basic embed form that directs to Constant Contact currently (first, last, title, company, email). I'm looking for ideas on how to simultaneously get this data to not only push to Constant Contact but also save data to local mySQL and push to Salesforce.  

Any ideas on how I could make this happen?

Thanks,
Crissy

This is the Constant Contact embed code used
