WP Mail SMTP is a plugin that helps you configure your WordPress site to send emails using a third-party SMTP service, rather than relying on the default PHP mail function. This simple change can improve email deliverability, ensuring that your emails reach inboxes and are not marked as spam.

What is WP Mail SMTP?

WP Mail SMTP is a WordPress plugin that enables you to send emails from your website using an SMTP server. SMTP (Simple Mail Transfer Protocol) is a protocol used for sending emails over the internet. By using SMTP to send emails, your emails are more likely to be delivered correctly, avoiding common email delivery problems like emails being marked as spam.

Why You Need WP Mail SMTP

1. Improved Deliverability: The default WordPress mail function uses PHP, which is not always reliable. Many hosting providers have limitations on PHP mail, which means emails may not be delivered. By using SMTP, WP Mail SMTP ensures that emails sent from your site are more likely to reach the intended recipient's inbox.

2. Avoid Spam Filters: Emails sent using PHP are often flagged as spam. SMTP services provide better authentication and reputation, reducing the chances of your emails being flagged as spam.

3. Email Logs: WP Mail SMTP allows you to log your email activity. This helps you track sent emails and monitor any issues in the delivery process.

4. Custom Mail Settings: With WP Mail SMTP, you can easily configure custom mail settings like sender name, email address, and more. You can also choose from various email service providers like Gmail, SendGrid, or Amazon SES.
