SMTP service

What is SMTP ?

SMTP stands for Simple Mail Transfer Protocol. It’s a protocol used to send emails across the Internet. SMTP works by guiding your email through various servers to reach its intended recipient. When you send an email, your email client interacts with the SMTP server to handle the outgoing mail. The server then communicates with other SMTP servers to deliver the email to the correct inbox. SMTP is crucial for email communication but it only handles sending emails, not receiving them; receiving is managed by other protocols like POP3 or IMAP.

Sending emails using SMTP

Configuring your web application to send emails via SMTP is straightforward. All you need to do is enter some credentials into a configuration file, and you’re all set to start sending emails in no time.
