Why smtp server

This protocol gets its name because it operates like a real-life post office in the digital realm. POP3 will receive emails and hold them for clients until they pick them up. All emails are downloaded and stored locally, making it a handy solution for someone who only uses one computer to check emails. In short, IMAP stores messages on an email server, but this server can be accessed by the user to check and configure their emails.

Ask us anything! Great deliverability without upgrading to dedicated IP. We disagree. In our example, the Website server connects with the Domain server, which if everything has gone right receives the email and stores it. The SMTP host simply drops the message to a backup server : if none of them is available, the email is queued and the delivery is retried periodically.

After a determined period, however, the message is returned as undelivered. Try it for free. We use cookies to ensure that we give you the best experience on our website. If you continue to use this site we will assume that you are happy with it.

Like most servers, the SMTP server processes data to send to another server, but it has the very specific purpose of processing data related to the sending, receiving, and relaying of email. An SMTP server is also not necessarily on a machine. It is an application that is constantly running in anticipation of sending new mail.

The SMTP server is able to process that code and pass on the message. Additionally, the SMTP server verifies that the outgoing email is from an active account, acting as the first safeguard in protecting your inbox from illegitimate email.

This informs the sender that they have the wrong email address or that their email is being blocked by the receiving server. Active free account customers can use their account to send test messages and test their email deliverability before upgrading and sending larger amounts of email. You just need to have an active Twilio SendGrid account and the ability to use basic username and password authentication within your email client or application.
