This blog lists the best WordPress SMTP plugins that will help you ensure better email deliverability for your business and promotional emails.

In the fast-paced world of digital marketing, effective communication is no longer optional—it’s a necessity! And, of course, email marketing is the key to effectively communicating with your target audience and achieving your marketing goals! 

But unfortunately, most emails sent directly from WordPress often end up in the spam box. Are you facing the same problem and looking for a remedy? Then, you’ve come to the right place. In this article, we will show you the best SMTP plugins to help you increase the deliverability of your business emails.

Having said that, let’s dive in.

How WordPress SMTP Plugins Improve Email Deliverability?

WordPress SMTP plugins serve as the bridge between your WordPress site and your email server. They ensure reliable and secure email delivery, empowering you to email like a pro.

Here’s why every WordPress user should consider using an SMTP plugin for their WordPress website:

  • Reliable email delivery: The default WordPress email function uses PHP mail, which lacks the necessary authentication and verification mechanisms. That’s why email servers often mark these emails as spam or not delivered at all. SMTP plugins, on the other hand, connect your website to a trusted SMTP server, which ensures more reliable email delivery.
  • Avoiding spam filters: SMTP plugins significantly reduce the risk of your emails being marked as spam. Email providers recognize SMTP servers, lowering the chances of your messages ending up in recipients’ spam folders.
  • Detailed email logs: WordPress SMTP plugins provide you with all the necessary data about your email campaigns and help you to keep them on track. Besides, these insights help you identify and quickly troubleshoot any potential issues.
  • Bulk email handling: For websites sending a large volume of emails, SMTP plugins efficiently handle bulk email delivery, maintaining email performance, and preventing server overload.
  • Customizable email settings: WordPress SMTP plugins let you customize the ‘From’ name and email address, adding a professional and personalized touch. This boosts brand recognition and increases email open rates.
  • Improved server reputation: By using reputable SMTP servers through the plugin, your website’s server reputation improves. This results in better email deliverability rates as email providers trust established servers.

Things to Consider Before Choosing a WordPress SMTP Plugin

The success of your email sending depends not only on your strategy or campaign design but also on how you choose your tools. And with countless SMTP plugin options in WordPress, it can feel overwhelming!

But, not fear! We’re here with the secret recipe. Consider the following factors before making your decision:

  • Compatibility and integration: Check if the SMTP plugin is compatible with your WordPress version and other essential plugins you use. Ensure it seamlessly integrates with your existing setup to avoid potential conflicts.
  • Ease of setup: Look for a user-friendly plugin with a straightforward setup process. An intuitive configuration wizard can make the setup hassle-free, even for beginners.
  • Supported SMTP services: Ensure the plugin supports the SMTP service provider you prefer to use. Popular providers like Gmail, Sendinblue, and Mailgun are usually supported by most plugins.
  • Affordability: Email marketing has the highest return on investment. However, in order to get the most out of it, you must first ensure that the instrument you are using is affordable. That is why you should go with a low-cost SMTP plugin. 
  • Advanced reporting: Data is important to keep you on track! A plugin with email logging and reporting features allows you to track the status of outgoing emails and troubleshoot any delivery issues effectively.
  • Support and Documentation: Check if the plugin has active support channels and comprehensive documentation. A responsive support team can help address any concerns, and thorough documentation aids in setup and troubleshooting.
  • User Reviews and Ratings: Before making your final decision, consider what other people say about the plugin. Consider their advice while selecting the best WordPress SMTP plugin for you.
