Are you looking for the best WordPress SMTP plugin? Then, you have come to the right place. As a WordPress site owner, you need to have an SMTP plugin that will ensure that all your emails reach your audience without any difficulties.

So, why do you need an SMTP server to send emails? First of all, WordPress doesn’t come equipped with a proper email solution. It does come with the PHP mail() function. But, it is not good enough as it fails to deliver every email. On top of that, not all hosting has the PHP mail() function configured correctly.

Emails are must-have for any website. They are required to recover lost passwords, get notifications, register new accounts, or to send newsletters.

By using an SMTP powered plugin, you will ensure that your users get proper email service when it comes to executing WordPress website functions.

Understanding SMTP

Before we go and list the plugins, let’s understand SMTP.

SMTP stands for Simple Mail Transfer Protocol. It is a standard when it comes to sending emails. You can find both free and paid service when it comes to SMTP. But for the most part, a free SMTP service can serve you well.

SMTP is very useful in sending automated emails. The traditional email services have a limit when it comes to emails. That means you send a certain amount of emails.

In short, you need an SMTP service. And, using an SMTP plugin will help you to manage the services better.

So, what are the best SMTP plugins? Let’s find out.
