What is SMTP?

Emails are sent over the internet using the basic communication mechanism known as SMTP, or Simple Mail Transfer mechanism. SMTP is the foundation of email delivery and is essential to the effective and reliable delivery of your messages to their intended recipients.

Message Routing

SMTP determines the route an email takes from the sender's server to the recipient's server, ensuring the message is directed accurately.

Reliable Delivery

Designed for reliability, SMTP minimizes the risk of message loss and guarantees that emails are successfully delivered to the recipient's mailbox.

Communication Between Servers

SMTP facilitates communication between email servers, allowing them to exchange information about the sender, recipient, and content of the email.

Text-Based Protocol

SMTP operates as a text-based protocol, using a set of commands to initiate, transfer, and conclude email transmission between servers.

Authentication and Security

Modern SMTP implementations often incorporate authentication mechanisms and encryption protocols to enhance security and protect sensitive information during transmission.

Integration with Email Clients

SMTP seamlessly integrates with email clients and applications, enabling users to send emails effortlessly from their preferred platforms.
