I want to know about the SMTP server configuration and what is the use of it because I need to send the messages in bulk sometimes they are not delivered, and it is difficult to keep track of it.

It will be very useful to use SMTP server configuration in case you want to send messages in bulk because it will take care of each and every message whether it is delivered or not. You can purchase it once and can use it many times whereas the simple free messenger won’t take the guarantee to deliver all the messages. For doing this, you will need to provide information like username, port number, etc. during installation.
