What is an SMTP Relay Service?
Simple Mail Transfer Protocol (SMTP) is a straightforward process that allows users to send, relay, and monitor outgoing emails. An SMTP relay service—also commonly known as an SMTP gateway service—takes this a step further by allowing you to send, receive and transfer more transaction and marketing-related emails. Instead of managing the logistics of your own program, you can trust the SMTP relay service to manage and maintain the SMTP server for you.
