SMTP (Simple Mail Transfer Protocol)
The primary protocol used by hosting servers to send outgoing mail, ensuring messages are transmitted securely.
SMTP, or Simple Mail Transfer Protocol, is the standard system used for sending emails across the internet. It works behind the scenes to move messages from your website or application to mail servers and then to the recipient's inbox. Configuring SMTP correctly improves email reliability, prevents delivery failures, and stops messages hitting spam filters. Most hosting plans include SMTP access by default, while some users prefer third-party email services for advanced analytics or better deliverability. A properly set up SMTP connection ensures your emails arrive securely, consistently, and on time, which is vital for professional communication.
