Plotting a large number of postcodes on a map using ZeeMaps

One of the many things I have to do at work is provide demographic data to the sales team to enable them to sell marketing opportunities to other businesses.

One of the main problems I've come across is being able to provide a sales-person-friendly geographic breakdown of our consumers stored in our CRM system. The main issue of this problem is the often incomplete address data we hold (arising from us using short and sweet sign-up forms online) and the lack of budget to get the data enriched with full addresses (using products such as AFD's Refiner).

I've tried using Google Maps and the KML file format, however, with both my out of date scripting knowledge and a large number of records this method has proven unworkable.

After searching high and low I found http://www.zeemaps.com/, a free and easy to use interface for carrying out many map based activities, one of them being plotting data on maps by submitting CSV files.

It's really simple to produce an image or PDF to show people a visual breakdown of where your comsumers live. Just create a map, go to 'Additions > multiple markers' and follow the instructions.

Here's a quick map I made:
