D for Domains in A to Z of Email Marketing

So what is a Domain
- SMTP

These protocols define the communication standard and type of data to expect. The sending server sends the data to another server by transmitting data over these protocols.
When sending data or receiving data how do servers identify each other?
Servers identify each other using IP Address. The domains names are basically nicknames / easy to remember reference of this address.
Especially when it comes to emails the data is transferred from one server to another via the SMTP Port. The Servers receive incoming data through this port and identify the sender, message information from the “Email Header”. The Email header contains important information about the email senders domain, ip address.
