Make 'From Sender' and 'footer' 'Smart' for automated emails


In HubSpot, we send marketing emails in the name of 10 countries (our public company address, like:, which means for ONE email, we need to create TEN due to the footer and sending address, we cannot use a uniform one, esp. from address, receiver will reply, we need to make sure that their reply goes to our right country. So is the footer, people might be confused for different information.


I found a similar request in Community (LINK), however I want the address from our public company address, which is different. 


Therefore, come here for help.
