I am an email marketing strategist, but today I am here to give you a glance at a very rarely heard term SMTP, this is the first part of a 4-5 post series in which I will cover what is SMTP, it’s the relationship with SMTP Server and SMTP relay. I know it must be very confusing for you all, and most of you, even the email marketers wouldn’t have heard this term.
So let’s begin without wasting any time!!
What is SMTP?
Simple Mail Transfer Protocol (SMTP), is a technology that makes it easy for emails to be sent from one server to another until they get to the final destination which is the receiver’s inbox.
This may look like a lot of technical concepts. Apart from that, I am going to break it down to the best level for you to understand in clear detail the workings of SMTP and why it is so important for business email. See SMTP as a virtual postman, that connects machines, to drop your emails at the right location.
While SMTP concerns itself with sending emails, the job of sorting them out and delivering them is done by different servers, called; POP (post office protocol) and IMAP (Internet message access protocol).
With emails, you will see the finest deployment of the basics of the division of labor. When you hit your send button on your emails, SMTP picks it out and delivers the mail to POP or IMAP. POP and IMAP will sort the server the email is to be sent to and deliver it right to the inbox.
In this article the intricacies of SMTP will be explained, giving you hindsight into what happens and how it happens. While you also get exposure to ways you can protect your business email and keep it safe from hackers and threats that happen on the SMTP servers.
Why the stress when you can simply send emails with your Gmail, Yahoo mail, Hotmail and AOL. The truth is, while the traditional mailing outfits work great for your one-to-one emails. You will have issues when you want to take on your bulk Emails or conduct email campaigns.
A fine way to meet success here will be your bulk emailing platforms and this platform runs on SMTP servers. This answers the question why? Let’s look at how the SMTP server works in fine detail below:
How SMTP works
Sending Emails Using SMTP
When you hit the send button on your office 365, Zimbra, G-suit, or other platforms you have chosen for your bulk emailing needs. It will automatically connect to your SMTP server, and provide it with details of your email. The server will carry the email, determine the receiver and the domain of the receiver. If the receiver is using the same domain as yours, the mail is sent immediately.
If the receiver is using a different domain, the email is handed over to IMAP or POP to sort the server out and get the mail to deliver. While SMTP is your postman for your emails, the delivery job is left for IMAP and POP, when the receiver uses a different domain from that of the sender.
All of this happens in such a fast sequence, that you cannot observe the intricacies and what happens when you hit the send button on your computer. Just like searching for a topic of choice on Google, it happens so fast that you do not need to bother just how it works.
