6 Best WordPress SMTP Plugins (Compared)

Last update on:

If you’re involved in web content development, then you’ve undoubtedly heard of WordPress. It is the leading content management software (CMS) and is preferred by anyone who enjoys developing and managing simple websites. WordPress, or WP for short, is the go-to platform for them.

One of the features that WordPress offers is the ability to accept public registrations, such as for a web host that accepts memberships or an eCommerce store. These types of WordPress websites need to send a lot of emails to their users.

However, if a site uses the default WordPress email solution, there’s a high chance that the emails will end up in the recipient’s spam folder and be missed by the users.

That’s why professional web developers use SMTP plugins. In simple terms, these WP SMTP plugins ensure that the emails sent by your website actually reach the users.

There are several easy-to-use WP SMTP plugins available, which can make it confusing to choose one. That’s why we have categorized the six best WordPress SMTP plugins in this article to help you decide.

What are SMTP Plugins?

You may be wondering what WordPress SMTP is. In short, SMTP, or Simple Mail Transfer Protocol, is a plugin service for sending and receiving emails. It is primarily a plugin for WordPress that manages the emails you send. It ensures that your emails are properly delivered to your recipients.

Most of the emails you receive are probably sent using an SMTP server. If you use the default WordPress mailing service, the emails are sent as PHP mail. However, this method is not very reliable and your emails may end up in spam folders. That’s why SMTP plugins are used.

SMTP servers are properly configured to ensure that the emails you send from your WordPress website do not end up in spam or junk folders.

What Is the Difference Between SMTP and WP Mail SMTP?

SMTP (Simple Mail Transfer Protocol) is a widely-used protocol for sending emails over the Internet. It is a standard method that enables email servers to communicate with each other.

On the other hand, WP Mail SMTP is a WordPress plugin that helps you configure and send emails using an SMTP server. It essentially allows you to use SMTP instead of the default mail function in WordPress, which can improve email deliverability and reliability.

Why is it Needed?

As mentioned before, the default mailing service of WordPress is not reliable. Even transactional emails sent through this service can end up in spam folders. That’s why it’s better to use plugins for WordPress to ensure that recipients receive their emails in their inbox. This is where SMTP servers come into play.

To send an email using SMTP, you need to use a plugin and connect it to a server. There are three possible routes:

First Route: Use the host’s SMTP server if available. However, not all hosts offer email hosting services, so this route may not be reliable.

Second Route: You can use SMTP servers provided by free email services such as Gmail, Yahoo, and Hotmail.

Third Route: If you’re looking for a more reliable option, you can use a third-party SMTP server dedicated entirely to mailing services. One popular option is Mailgun, but there are other reliable ones as well.

What Are the Risks of SMTP?

SMTP (Simple Mail Transfer Protocol) is generally considered to be a secure protocol for email communication. However, there are a few risks associated with SMTP:

  1. Spam and Phishing: SMTP can be vulnerable to spam and phishing attacks, where malicious actors send unsolicited emails or attempt to deceive users into revealing sensitive information.
  2. Email Spoofing: SMTP does not provide built-in mechanisms to verify the authenticity of the sender’s identity. This can lead to email spoofing, where attackers forge the “From” address in an email to appear as someone else.
  3. Data Interception: Without additional security measures such as encryption, the content of emails sent through SMTP can potentially be intercepted and read by unauthorized parties during transit.
  4. Email Bombing: SMTP servers can be targeted with large volumes of emails, causing server overload and disrupting normal operations.

Is There an Alternative to SMTP?

Yes, there are alternative protocols that can be used for email communication:

  1. IMAP (Internet Message Access Protocol): IMAP is another widely used protocol that allows users to access their emails stored on a remote mail server. It offers more advanced features and better synchronization capabilities compared to POP (Post Office Protocol).
  2. POP (Post Office Protocol): POP is an older protocol that enables users to download emails from a remote server onto their device’s local storage.
  3. Exchange ActiveSync: Exchange ActiveSync is a proprietary protocol developed by Microsoft primarily used for syncing email, contacts, and calendar data between servers and mobile devices.
  4. Webmail Interfaces: Webmail interfaces provided by email service providers allow users to access their emails directly through web browsers without the need for any specific protocol.

Note: While these alternatives exist, SMTP remains the dominant protocol for sending emails across different servers on the internet due to its widespread support and compatibility.

Final Words

Whether you’re sending a newsletter or a service email, using plugins ensures that your messages reach the client’s inbox instead of the junk folder. That’s why WordPress developers and webmasters need a highly-rated WordPress SMTP plugin.

It guarantees reliable email delivery and increases the chances of your emails being noticed and acted upon by recipients. A good plugin is essential for effective communication and maintaining a professional image.
