Inboxroad is email marketing company from Amsterdam. They are awesome guys and it was my pleasure to work with them.
My job was to build a completly new website from scratch. Their only demand was to build it in WordPress. Since there were some custom plugins I decided it's best to build this as a WordPress theme in PHP. All data coming from backend is displayed on the template frontend with the help of WordPress functions. Most of the site is editable by client in WordPress admin.
Inboxroad team had some demands about functionalities they needed - so i built few small plugins that help them function. Also pricing page was fully customizable with WooCommerce. At the time of writing, potential customers could choose from 4 different pricing plans with different variations.
On frontend, SASS is used to support Bootstrap layouts. For functionality I used jQuery.
