Why Use a WordPress SMTP Plugin?

By default, WordPress uses the PHP mail () function to send emails from your WordPress website.

These include order confirmation emails for customers in your WooCommerce store, transactional emails, form submission emails, newsletters, account activation emails, and more.

However, due to server issues, plugin conflicts, or incorrect email settings, most of these emails never make it to the users’ inboxes or even end up in the spam folder.

For more details on this, you can see our beginner’s guide on how to fix the WordPress not sending email issue.

This is where SMTP plugins come in. These plugins easily integrate with popular SMTP services to improve the overall deliverability of your emails.

SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails. Unlike the PHP mail () function, it uses proper authentication, making SMTP a more reliable protocol with high deliverability rates.

Plus, an SMTP plugin encrypts all your emails to prevent them from being intercepted by hackers.

They also give you more control over your email settings and let you customize the email that will be sent to the recipients.
