What is SMTP?
SMTP (Simple Mail Transfer Protocol) is the standard protocol used for sending emails across the internet. It enables websites, applications, and servers to deliver transactional messages, notifications, and automated communications reliably. SMTP ensures consistent email delivery by routing messages through authenticated mail servers with proper security and deliverability standards.
