The way people used to communicate has changed. Nowadays email is considered one of the most trusted ways of communication for business. This is where WordPress SMTP plugins come into play.
When it comes to website and users’ communication email stands still. An SMTP service provider helps websites to send various emails from the website backend to their users. WordPress is designed through PHP and uses the same to send emails by default. SMTP plugins are there to send emails properly.
If you are looking for the best WordPress SMTP plugins then you are in the right place. In this post, I am going to share some of the best service providers in this category with high email deliverability.
So let’s get started.
What is an SMTP Service?
SMTP also called Simple Mail Transfer Protocol is an industry standard for sending and receiving electronic emails using the internet.
It is a type of software used for sending and receiving emails to other computer/server users based on unique e-mail addresses. The main purpose of the SMTP server is used to set up different communication rules between servers.
When you send an email, an SMTP server works in the backend that breaks it down into small relevant parts. It helps the email to move from the sender’s email client to your recipient’s email client.
The servers are configured with built-in programs to perform communication and email delivery. They also have a built-in identification system for handling various errors such as incorrect email addresses.
If you try to send an email address with a wrong address, then the server checks it first and replies with an error message of some kind.
It uses a high-end authentication algorithm to increase the possibility of emails being delivered to the recipient’s primary inbox and doesn’t end up in the junk mail folder. Most of the emails you found in your inbox these days come from an SMTP server.
