ImpersonalEmails are less personal compared to many other forms of communication, such as talking over the phone, or meeting face to face.2. MisunderstandingsIt is easy for misunderstandings to occur with email, as there is only text and no tone of voice, or body language to provide context. Jokes can be mistakenly taken seriously. A well-meaning but quickly typed email can come across as rude, or aggressive. Short descriptions and abbreviations can easily be misinterpreted.3. Heat of the MomentAn email fired off in the heat of the moment can cause a lot of anger or upset, especially in the workplace, or in a romantic relationship. Even worse, emails are impossible to delete or edit once sent.4. Malicious UseEmails can be sent anonymously, which means that they are sometimes used maliciously to bully or upset people. Likewise, they can used to spread gossip, or false information.5. Accidents Will HappenIt is relatively easy to make catastrophic mistakes with email by clicking the wrong button. For instance, you can accidentally send sensitive information to multiple people rather than just a single, intended recipient. Alternatively, you can send an email to the wrong person by not realizing that you’ve clicked the wrong name in an address list. In the workplace, mistakes like these can result in big trouble, even getting fired.6. Information OverloadIn part because emails are so easy to send to multiple people, they can create information overload. It's a huge problem in many modern workplaces, where there is a lot of information moving around and impossible to tell if an email is important or relevant without opening and reading it. Emails require constant organization and upkeep. Returning from vacation to find hundreds of unopened emails in your inbox is one of the worst feelings in the world .7. SpamAlthough the situation has improved in recent times, there are still major problems with spam and unsolicited advertising arriving via email. It takes time and energy to control and can easily become overwhelming.8. VirusesEmail is one of the commonest ways for viruses to travel and infect devices. The email might come with a virus, or the virus might be in an attached document. Infection normally occurs when the recipient clicks a link or opens the infected attachment. Infected emails may come from an anonymous source, or appear to come from a trusted friend or contact.9. Time ConsumingReading, writing and responding to emails can take up vast amounts of time and energy. Many modern workers spend most, if not all their days just dealing with them. This work can be dull and sometimes it feels like there are few tangible benefits.10. Pressure to RespondPeople get annoyed if you don't answer their emails, they think you are ignoring them, so there is a constant pressure on you to keep opening them and then respond in some way.11. InsecureEmails are a common target for hackers seeking sensitive information, such as financial, political, or personal messages or documents. There have been many high profile cases recently that have shown how vulnerable email is to data theft. It's also the case that so many emails fly around in a large organization that it can be difficult to know who has what information, another security issue.12. Overlong MessagesEmail is a form of communication that is generally intended to be brief. Some people seem unaware of this and write overlong messages that take up far more time than necessary.
