The Importance of Email

In today’s world, we have happily taken on our inner cyborgs.
We connect in seconds with others. Social media, cell phones, and apps have shown us the ease of short direct messages.
Yes, email has been around since the early ’70s. But, it’s not going anywhere.
Emails allow us to maintain professionalism in business relationships. Your job may require you to work in a remote setting or in an office.
Still, emails are often the preferred choice of communication.
If you’re running your own business you might have to send multiple receipts or samples to a client. Emails have the service power to send the applications you need.
Emails also keep communication at a good distance.
Take academic communication for instance. Professors use emails to send an entire class assignment instructions.
Imagine if a professor tried to call every student to explain a paper topic… that might be a little awkward. It would definitely be time-consuming.
Email serves us in so many ways until it doesn’t. To better understand our online communication we must take a better look at how we check our email.

Webmail VS Email Clients

Most of us have more than one email account. We separate emails by their purpose.
An email account just for business, for personal, for school, and for subscriptions. You can access accounts either through webmail or an email client.
Email protocols, such as IMAP and POP3, have different advantages and disadvantages for email clients.
Webmail is an email account hosted through a browser. For example, think Gmail, Yahoo! iCloud,, and MS Exchange.
Each webmail account can only be viewed separately via different browser tabs.
To check notifications and carry out email actions, you must access each account one at a time. Not to mention you must have internet access as well.
If you only have one email account you can commit to webmail with no problem.
But, when you’re using more than one email account that’s when email gets tricky.
Instead of webmail, you can use an email client. These are programs you can download onto personal devices. Email applications let you see all your email accounts at once.
