Hi Priyanka,
There are three Approaches to choose for your reply to and sender address.
Traditional Approach
The traditional approach is to use a single, consistent response address for reply and sender address. However, Traditional addressing has two main problems. First, the reply address may not be the same as the sending address. This can be the case for a number of reasons, including mail forwarding, address aliasing, or even role addresses. It’s often impossible to use the same address for both.
Dynamic Address Approach:
Choose one sender address. It’ll be consistent, recognizable, branded, and easily added to a recipient’s address book.
Choose different mail-box address as a reply to address based on the Brand, Department, Campaign goals, as Most of the companies have a different person responsible for responding to the acquisition or Remarketing or other campaigns.
Use one address for Sender address like Dynamic Address but use a different address for Reply-to address.
This simplifies the process but your marketing team has to work extra hard to monitor the email box.
To answer your last question, Reply address has a mailbox server.
Regards,
Amit
