Now how do I reach the admin area of my site?

In the new sitebuilder you can just log in with the controlpanel data you received by mail. If you have changed these data then you will have to use them.

To change your website created with the (new) sitebuilder, log in at https://www.mijnsitebuilderpartner.nl.

Please note! For customers that are still using the old sitebuilder, the following applies!

You can reach the admin part of your website by putting the following after your domain name:

admin/

So you get eg:

https://www.denaamvanjesite.nl/admin/
