SMTP = Simple Mail Transfer Protocol
Simple Mail Transfer Protocol (SMTP) is the standard protocol used to send emails across the internet. It handles how email servers talk to each other to move your message from your outbox to the recipient’s inbox. It’s mainly for sending (not receiving) emails, and most bulk email tools or services are built on top of SMTP to handle large volumes efficiently. for learn More visit our website SMTPWIRE
Most SMTP implementations support at least the basic set of SMTP commands defined in RFC 5321 — like HELO/EHLO, MAIL FROM, RCPT TO, DATA, RSET, VRFY, NOOP, and QUIT. These are enough for standard mail delivery and are almost universally supported. If you’re curious about extended commands (like AUTH, STARTTLS, etc.), they depend on the server’s configuration and what extensions are advertised in response to EHLO. WarmupSMTP Company
