The 8 Best SMTP Plugins for Your WordPress Site

Most WordPress users face email sending issues. The reason behind that issue is, WordPress uses PHP email functionality. However, the shared hosting service disables the PHP functionality. That’s why you can’t send emails from your WordPress site. But you can use a third-party SMTP plugin to send emails from your email service providers. But there are multiple reasons why you might need an SMTP plugin. The most common reasons are poor authentication or your host blocking email delivery. The less common is bulk mail overload and being marked as a spammer due to this. It is why we have respective features for both situations. The email logger is the most important.

Your host might have PHPmailer disabled. In this situation, your WP emails are plain and straightforward, not delivered, as WordPress uses the PHPmailer by default to send mail. Poor authentication due to PHPmailer. It’s a highly complex process to properly set up a PHPmailer on a small WordPress site. In most cases, setting up PHPmailer will result in your emails being either undelivered or sent to the Spam folders. The cause for this is that PHPmailer doesn’t use any sort of authentication. The email service providers don’t know whether the emails they’re receiving are coming from a legitimate sender or not.

Email is often the preferred method of sending information online, so this service makes sense that email is also an important part of running a successful WordPress site. SMTP, or Simple Mail Transfer Protocol, is a very simple communication protocol that allows email transfer over the internet. In addition to making your website’s email more secure, having the SMTP gateway helps prevent WordPress emails from being blocked by popular free email providers like Gmail. Having a reliable SMTP plugin is a better idea for any WordPress site. While sending an email, an SMTP server breaks down your email into its relevant parts. So basically, it helps move it further from your email client to your recipient’s email client. Also, most of the emails there in your inbox are probably from an SMTP server.

These SMTP plugins allow the site admin to choose which SMTP service to use and bypasses the normal WordPress email functionality. While an SMTP plugin can seem very technical, it is ideal for all types of WordPress users. Bulk sending overload can happen even on SMTP. If you send hundreds of emails per day via a free SMTP provider, you might be a victim of a lesser-known problem. Sending this many emails puts a lot of load on the undedicated SMTP provider’s servers. Only a dedicated server such as Mailgun or SendGrid can handle large loads of outgoing emails daily.
