How Does SMTP vs IMAP vs POP3 Explained - Tutorial by Mailtrap Work?

Sending and getting emails is like sending letters through different post offices. SMTP, IMAP, and POP3 are like special ways of handling those letters.

Imagine you're writing a letter to your friend, and you hand it to the postman who takes it to the post office, that’s like SMTP (Simple Mail Transfer Protocol). It helps send your email from one place to another.

Now, when your friend gets the letter, they might read it right away or keep it in their mailbox for later. That’s like IMAP (Internet Message Access Protocol), it lets you see your emails on different devices, just like having a mailbox that stays full no matter where you check it from.

But if your friend takes the letter home and keeps it in their own drawer, never to be seen again, that's like POP3 (Post Office Protocol version 3). It downloads your email to one device, like taking the letter out of the mailbox and keeping it at home.

Mailtrap is like a special post office where you can see what letters are being sent before they go anywhere else. It helps people test their emails, just like checking if the postman delivered everything right!
