<p>SMTP, or Simple Mail Transfer Protocol, is the industry standard for sending emails across the internet. It plays a critical role in the email delivery process, acting as the protocol that governs the transmission of emails from one server to another. Understanding SMTP is essential for anyone managing email communications, particularly in a WordPress environment. If you do not use a proper SMTP relay service, your emails might go to spam, compromising their effectiveness and reach.</p>
<h4>HTTP API Integration</h4>

This is a great option for users whose hosting providers block SMTP ports or for those who prefer to use the Maileroo API for email delivery.</p>
