What is SMTP

SMTP stands for “simple mail transfer protocol.” It’s a service that helps send emails from one computer to another. By managing how emails move between servers, SMTP ensures your message gets delivered to the right place safely and securely.

About KingSMTP

KingSMTP.com (formerly known as Kingmailer.co) is an SMTP service provider that focuses on delivering transactional emails. It’s designed to help businesses reliably send emails such as order confirmations, password resets, or notifications, but it’s not intended for mass email campaigns or marketing.


Why KingSMTP?

KingSMTP focuses on ensuring that your transactional emails are delivered quickly and reliably. By using dedicated SMTP servers with global distribution, we optimize delivery times and reduce latency, ensuring your messages reach inboxes without delay.

Our SMTP service is designed to integrate seamlessly with your existing email infrastructure. Whether you’re migrating from another SMTP provider or setting up a new email system, KingSMTP allows you to switch with minimal code changes, offering a smooth transition.

At KingSMTP, we prioritize the security of your emails. With TLS encryption, we ensure that both your authentication credentials and the contents of your emails are securely transmitted, protecting your data from potential breaches.
