Plotting the IP address alone can sometimes be unreliable as this isn't always a true reflection of where your contacts actually are. For one, the high usage of mobile devices means people often read emails whilst on the move. You really want to know actual, physical location of where the interest is based, not where they happen to be when they open or click. 

Interested in the exact location of your individual contacts? If you have uploaded the post codes of your recipients you can easily see where they are located through our Google Map integration. The maps can also be filtered by contacts that have opened your email or contacts who have clicked through to your website. Click on the map pins to find out the exact email addresses.  
And so now you can. If you upload a contact list with a UK postcode for each contact and run a campaign, you will be able to plot the location of where they are based, like this:

As you would expect from the use of this type of map, you can pan around the world and zoom right down to street level. You can plot either opens or clicks. This is very useful if you are interested in knowing where your contacts are located, and identifying pockets of interest.
