What is SMTP?
SMTP, as you might know, stands for Simple Mail Transfer Protocol which is a protocol used for sending and receiving emails over the network. So how SMTP works is that when you send an email, its server breaks it down into its relevant parts.
This helps move it from your email client to your recipient’s email client. And therefore, most of the emails that are floating in your inbox probably would have come from an SMTP server!

Why do you need an SMTP Server?
Since not all emails are transferred successfully as some of them get bounced over the network, the email open rate eventually lowers down. This is where the SMTP comes handy.
With SMTP installed on your website, you can send emails via a properly-configured SMTP server, rather than your WordPress site’s server. And, with this setup by your side, your WordPress site will send the email to the SMTP server. This then processes the email and sends it on to the proper destination which here, in this case, is the recipient’s inbox.
Now because the SMTP server is configured in such a way that it handles sending emails with proper authentication in place, your emails deliverability rates are improved and the chances of your email making it to recipients’ inboxes also become better.
Which one to pick – SMTP or API?
If you are a developer then you would be in the constant battle to choose between SMTP and API. You would find many articles that would help you choose which is best for you but you might still be confused.
So, let’s try to understand both so that we can pick the best one!
SMTP, on one hand, is a set down procedures for sending emails/messages to an email server. API, on the other hand, stands for Application Programming Interface and is a means by which different applications, platforms, software, and codes communicate with each other and share resources.
Well, for starters, SMTP is the more widely accepted of the two, for here you need not worry about the terms of integration and usage. Whereas on the other hand, its easier to send emails and automated process through API app or platform .
SMTP by extension requires little or no knowledge of coding while Web API gives you the benefit of adding an extra layer of security to your program by utilizing API keys.
That being said, SMTP relay can also be used to connect with an existing application like a CRM system. The Web API is often utilized by developers creating their own product. And therefore, SMTP is an email standard and used universally.
Guess, we have pretty much talked about SMTP. Now let’s dig into our subject matter!
