Each email form you create has its dimensions set in pixels. A new email form has a default size of width:727 px and height:506px which can easily be changed.
the size of the email form is especially important if you intend to embed it in your website/blog because when
you embed an email form you usually have a limited space for it (which it cannot exceed).
*please notice that any changes in the email form size after it has been embedded will require you to publish it and embed it again.
In order to change the size of the email form you only need to:
1- enter the email form2- go to its ‘form settings’ on the right
3- change the width and height numbers
4- press on ‘apply’
5- save the email form
