The Problem

Being an owner of a WordPress website, you may have faced issues related to emails not reaching the intended recipient’s inbox. This issue is common yet solvable. With the right knowledge and tools, you can ensure all your important emails are delivered successfully.

This comprehensive guide will explore how to prevent your emails from getting lost from your WordPress site. We will discuss email delivery service and SMTP tools in WordPress.

What types of emails does WordPress send?

This will depend on your WordPress setup. Different plugins and tools will send different emails.

Some examples of emails sent by WordPress CMS are:

  • Forgot password emails: These emails are sent to users when they forget their password. They typically contain a link that allows the user to reset their password.
  • User emails: These emails are sent to users to inform them of new content, updates, or other changes to the website.
  • Form responses (Gravity Forms, WP Forms etc): These emails are sent in response to form submissions. They can be used to send confirmations, receipts, or other information to the user.
  • Security alerts: These emails are sent to users to warn them of potential security threats. They can be used to notify users of suspicious activity, such as unauthorized login attempts.
  • WooCommerce or other e-commerce emails: These emails are sent to users to inform them of order status, shipping information, or other updates related to their purchase.
  • BuddyBoss member platforms: These emails are sent to members of a BuddyBoss-powered community to inform them of new content, updates, or other changes to the community.
  • Statistic tools or plugins: These emails can be used to send reports or notifications about website traffic, analytics, or other metrics.

As you can see, the range of emails can vary and this can change the importance of email management for your platform.

Understanding the Email Deliverability Issue in WordPress

WordPress is a powerful content management system (CMS). It is programmed using PHP, a popular scripting language for web development. One of the PHP functions is to send emails.

However, due to certain limitations, the PHP mail() function is not the most reliable method for delivering emails.

Some hosting providers disable the PHP mail function to prevent misuse of their email delivery service for spamming. This might leave you unable to send or receive important communication. You may fail to send sign-up confirmations, password resets, purchase confirmations etc.

Furthermore, email providers scrutinise all incoming emails to determine their credibility. If they find any discrepancy, such as the email claiming to be sent from a different location than it originates from. They might block it altogether.

How Can SMTP Resolve Email Delivery Issues?

SMTP (Simple Mail Transfer Protocol) is the industry standard for email delivery. It addresses the PHP mail function’s limitations in WordPress. It changes how your website sends emails and authenticates them correctly.

Implementing SMTP into your WordPress website improves the email delivery service. This is where the SMTP WordPress plugins come into the picture. They make the integration of your WordPress site with an SMTP server smoother, ensuring that your emails reach the intended inbox.
