How to Use Gmail SMTP,POP Server For Applications

Have you ever thought about how to receive and send email? SMTP is one of the TCP/IP protocols that is used for this purpose.

But what is the SMTP protocol and what should be known about it? Just be with us for 5 minutes to learn it.

What’s SMTP Server ?

The SMTP (simple mail transfer protocol) protocol is a simple e-mail transfer protocol and, as mentioned in the introduction, it is used to send and receive e-mails.

This protocol is usually used with POP3 or IMAP protocols due to limitations in mail storage.

This definition was part of the early definitions of the SMTP protocol in network science and includes the latest definition and its updated version, Extended SMTP (ESMTP). Today, this protocol is widely used.

SMTP is not a server and you cannot compare it to a server. If we want to say what SMTP is, we must say that it is a program that allows sending and receiving emails. But sometimes it is named as an SMTP server. There are a lot of free SMTP servers.

SMTP allows users to store email on a server or download it from a server. In fact, we can say that SMTP is used to send emails and POP3 or IMAP is used to receive emails.

How To Work SMTP Server?

An SMTP server is like a web server on a computer that acts as a router. When it receives e-mail messages from users, it sends them to the intended recipients.

What’s SMTP Port

The SMTP protocol, or e-mail sending protocol, usually uses port 25 to send mail. The POP3 protocol is the most common standard protocol for receiving mail, which uses port 110 to receive mail. In addition to this protocol, there is also IMAP.

Send WordPress Emails Using Gmail SMTP

With only one free Gmail account, you can send up to 500 emails per day, which is significantly higher than the limits imposed by other free SMTP servers.

If you have a Google Workspace (G Suite) account, Google increases your limit even further, allowing you to send up to 2,000 emails per day.

You can also send emails from your custom domain name instead of your Gmail address.

That means you can send messages from you@yoursite.com instead of you@gmail.com.

Note : Technically, the posting limit is not “per day”. Instead, the restrictions apply to a “24-hour“.

You cannot, for example, send 500 emails at 11:59 p.m. on Monday and another 500 at 12:01 a.m. on Tuesday.
