Keeping track of outreached publishers?

Hi,

I wonder if anyone of you could recommend me a tried-and-tested tool (something like a CRM) to keep track of outreached publishers.

Right now, I use a very rudimentary CRM I made in MySQL and PHP and run on XAMPP locally plus a bunch of large spreadsheets on Google Docs but it's by far not the perfect solution.

I need something where I can keep track of the emails I send out to webmasters, their replies, the prices they ask for publishing a sponsored guest post (+ the currency), their special requests, the other websites in their portfolios, their websites' language, target country, and a ton of other details. It's a pretty long list of contacts, too, with thousands of potential partners and tens of thousands of URLs.

Any help will be highly appreciated. Thanks in advance.
