The acronym SMTP stands for Simple Mail Transfer Protocol, the procedure behind the email flow on the internet.
The main purpose of using these servers instead of Common Email Providers is Scaling which is only possible with Dedicated SMTP servers. When a user sends an email, the SMTP server processes the email, decides which server to send the message to, and relays the message to that server. The recipient’s inbox service provider, such as Gmail or AOL, then downloads the message and places it in the recipient’s inbox.
