I am always amazed at the number of customers that still have AOL email accounts. What is even worse is that they are usually POP accounts and these customers are managing their email on multiple devices. I don’t mean to trash AOL too much, but if you are still using an AOL email account you should change. AOL just doesn’t work the way the rest of the world does, especially when it comes to handling attachments in email.
When you read an email message on your iPhone and delete it, do you have to trash it again when you check mail on your Mac or your iPad? Or is your email kept in sync so that if you delete a message on one system, it never even appears on the other?
If you fall into the first camp, your internet service provider probably has you stuck using an email technology called POP. Conversely, if you’re in the second camp, you’re probably using a different email technology called IMAP. Don’t worry what POP and IMAP stand for—they could be called Spot and Jane for all that it matters. What does matter is that if you’re using POP to read email on more than one device, you’re wasting time and effort and using old technology.
POP was designed in 1984 so that every email message would be downloaded from your mail server and immediately deleted from the server, so the only copy would exist on your Mac. But that made it impossible to check email from more than one computer, so POP’s designers made it possible for a message to be downloaded but not deleted, so it could be retrieved again by another computer. But the POP server has no way of knowing that the message was transferred multiple times, so each computer that gets it sees it as a fresh message, forcing you to delete or file it in each place.
In contrast, IMAP, which came along just a couple of years later in 1986, was designed to keep all your email on the mail server itself so multiple computers could access the same set of messages. And, most important, anything you do to a message—delete, file, or reply—in your email app on one computer also happens on the IMAP server, so if you check email from another computer, your email collection reflects all those previous actions.
Fast forward to today, where you might check email with your Mac at work, with your iPhone while at lunch, and on your iPad at home. If your internet service provider is using IMAP, anything you do on any of your devices is reflected on all the rest. As an extra bonus, you can search through all your email at any time, from any device, which is great when you realize you need the address for today’s meeting after you’re in the car.
But some ISPs still rely on POP, and for those of you who have had the same email account for many years, even if your ISP supports IMAP, they may not have switched you over. If your email is stuck in the POP past, call your ISP and bring your email into the 21st century. If they aren’t willing to help, remember that you can always use your free iCloud email account instead or sign up for a free account with Gmail or Yahoo.
For those who are shaking your heads because you don’t want some IMAP server in the cloud to hold the only copy of your precious email, rest assured that it doesn’t have to be that way. By default, Apple Mail downloads a copy of every message and keeps it locally on your Mac too, so even if something bad were to happen in the cloud, you’d still have your local copy and your backups of it.
Life is too short to waste time dealing with the same email messages on multiple devices. Computers and smartphones are supposed to make things easier, not harder, so if you’re not already using IMAP for email, do yourself a favor and switch Now!
