Difference between IMAP and POP3

IMAP stands for “Internet Message Access Protocol”. It’s a fancy name for a protocol used by email programs like Outlook, Thunderbird, and others to access your email.
IMAP is an alternative to POP3 (Post Office Protocol 3), works in some fundamentally different ways, and makes a few fundamentally different assumptions.
IMAP and POP are two different protocols. There are many differences between these two. The main difference is that IMAP(Internet Messaged Access Protocol) always syncs with mail server so that any changes you make in your mail client (Microsoft Outlook, Thunderbird) will instantly appear on your webmail inbox.
On the other hand, in POP(Post Office Protocol), your mail client account and mail server are not synced. It means whatever changes you make to your email account in the mail client will not be transferred to the webmail inbox.
In simple terms, if you are using IMAP and mark a mail as read, it gets marked as read in your web based inbox too (because the changes are happening on the server). However, this won’t be the case if you are using POP, because the mails are downloaded to your PC and the changes won’t reflect on the server.

Automatic Reply Emails Example

A professional automatic reply email is good when it is written with clarity. However, it is not necessary to start with ‘Dear esteemed customer’, you can start with ‘Dear friend’ or “Hi there” in order to create a good atmosphere of relationship with your customers.
The following example is an email that is clearly written.

Hey there,
