My question in preview template email footer the img logo dan icon sosmed already show up but in the other template email such as new order email template, new account email template etc, img logo and icon sosmed can't  show up, what's wrong? or maybe because im using block for img footer and icon sosmed? beacuse I don't know how put img logo footer and icon sosmed in email footer template.
