Email jargon can feel overwhelming, but let’s break it down into plain language. Today, we’ll explain IMAP, SMTP, and a bit about POP3.
By the end, you’ll know exactly how these protocols help your emails move around.
What Is IMAP?
IMAP (Internet Message Access Protocol) keeps your emails in sync across all your devices.
For example, if you read or delete an email on your phone, those changes show up on your computer, too.
In short: IMAP = synchronized emails across devices.
What Is SMTP?
SMTP (Simple Mail Transfer Protocol) handles the sending side of email.
It takes your email, delivers it to the recipient’s server, and ensures it arrives safely.
So, IMAP is for receiving, and SMTP is for sending.
How Do IMAP and SMTP Work Together?
Think of SMTP as the postman delivering your mail. IMAP is like having a helper who organizes your inbox so you can easily access it from anywhere.
SMTP sends the email, and IMAP keeps it neat and updated.
What About POP3?
POP3 (Post Office Protocol) is another way to access emails, but it’s less common now.
With POP3, your emails are downloaded to one device, and then they’re deleted from the server.
This was useful when people used offline email apps, but it’s not ideal for today’s multi-device setups.
Quick Recap:
- IMAP = Sync emails across devices.
- SMTP = Send emails.
- POP3 = Download and delete emails.
