7 Best WordPress SMTP Plugins for Better Email Delivery

Are you looking for the Best WordPress SMTP plugins? Then you have come across the right post. A WordPress SMTP plugin can help to fix all your email deliverability issues, by using an alternate way from your typical WordPress default email solution.

If you are running a membership website or your WordPress site allows public registration and you need to send transactional emails to users, such as confirmation emails or password reset emails. It is likely that a significant number of these emails will be directed to spam folders when using the default WordPress email solution.

This is not ideal, as you want your emails to reach their intended recipients. This is why using a WordPress SMTP plugin can be beneficial. In this post, we will introduce you to the top 5 WordPress SMTP plugins and provide an ultimate comparison to help you choose the best one for your site.

What is SMTP and How it works?

SMTP or Sending mail Transfer protocol is a set of rules used for sending, receiving, and relaying email messages from one computer to another. It is a standard protocol for transmitting email over the internet and is used by the majority of email servers and clients for sending and receiving emails.

Here’s how SMTP works:

  1. When you send an email from your email client (such as Gmail or Outlook), the client uses SMTP to communicate with the email server and transmit the message to the recipient’s email server.
  2. The email server receives the message and checks to see if the recipient’s email address is valid.
  3. If the address is valid, the server sends the message to the recipient’s email server.
  4. The recipient’s server receives the message and delivers it to the recipient’s email client (such as Outlook or Thunderbird).
  5. The recipient’s email client displays the message in the inbox.

Overall, SMTP is a reliable and efficient way to send and receive emails and is widely used for both personal and business communication.

Why do you need to use WordPress SMTP plugins?

By default, WordPress uses the PHP mail () function to handle all emails sent from the website. However, this method is not always reliable and may result in emails being landed in the spam folder. Therefore, to fix this problem, you are required to use a reputable and trusted third-party email service.

A WordPress SMTP plugin can help improve the deliverability of emails by connecting your website to a dedicated email service and adding a layer of security to it. This helps to bypass spam filters and ensure that the emails are delivered to the correct inbox.
