Emails have become a normal part of our lives over the last few years. It is perfectly normal to not only use emails for work, but also to communicate with friends and family via email. Let us first of all look at an advantage of private emails.
You might want to look into the fact that emails are very convenient, as they are so easily accessible. You can access your emails via your phone, computer, tablet. It doesn't matter where you are—you can always access your emails and respond quickly to them. For example, if a friend invites you to a spontaneous party via email, your phone will probably alert you to the fact that you have just received an email. You can then read and respond to this invite straight away, which makes communication a lot quicker compared to traditional ways of communicating.
However, there are also disadvantages when it comes to using email for private communication. You might want to mention the fact that sometimes emails can be quite short and abrupt, as they are often written in a rush. People rarely take the time to reread their emails before sending them, they usually just write them and send them straight away. This can make emails sound quite harsh, even if they had not been intended to sound harsh. It is not uncommon for misunderstandings and possibly even conflicts to arise from this, as the reader of an email may well misinterpret what they are reading and take offence at something that wasn't actually intended to be taken as such, just because the email had been written hastily.
