The Death of POP3 Email

If you’re still using POP3 or IMAP email, I have just one question for you.




POP3 worked great when it was released 35 years ago, but today it limits your business.


Many people complain that their emails (including sent + deleted) do not synchronise across their PC or Smartphone (or any device for that matter). Every time this turns out to be because the client is using POP3…in 2017!


Here are some more reasons why POP3 is a dying cause…


Unsecure Connection

Authentications are done in plain text, which is susceptible to man-in-the-middle attack.

No Device Synchronisation

Emails sent and received on one Device (E.g. PC) will not be accessible on another (e.g. mobile).

No Shared Calendars

No Back-up

• Poor mobile compatibility


The Rise and Fall of POP3


POP3 email, was popular and widely used when it was released in the 80’s. However, in March 1996, large companies left POP3 and incorporated the Microsoft Exchange server which gave them a corporate level of email functionality. This was costly and at the time, could only be afforded by large companies.

Small businesses on the other hand were left with POP3, that is, until June 2011.

In June 2011, a solution was released to the world which gave small businesses the opportunity to have the same email features as large companies, for a small monthly charge.

This made it entirely possible for small businesses to work as efficiently as large companies without spending huge amounts of money.


Here are some reasons why Office 365 is taking POP3’s place…

Secure Connection

Authentications are over secured channels

Full synchronisation

Between the mail client and the server, meaning you will not get duplicate emails.

Shared Calendars

You have the ability to share your calendars with the ability to control the amount of information accessible.


Office 365 works as part of your disaster recovery plan.
