Hello,
You have provided the incorrect pass and I can’t login.
Anyway, if you need to add the newsletter form you may use MailChimp plugin and create the form with the necessary structure + custom styles to make it look exactly as on that example. Unfortunately, such individual customization is not included in our support. You may contact customization team https://wpkraken.io/?ref=8theme if you need help with this.
Regards
