Sometimes data is not stored in a cookie, but in the 'local storage' of your browser. Eneco uses HTML5 Local Storage to store data. This works in much the same way as cookies, but more data can be stored. With local storage, you decide how long the browser stores the data. This depends on your browser settings and/or how often you clear your browser history.

Tracking pixels

A tracking pixel is an electronic file (normal size 1 pixel x 1 pixel) that is placed in an e-mail (for example our newsletter). By using a tracking pixel we can see whether an email is read.
