There are disadvantages to email as well.
The main one is that a computer has got to be on in order to receive  emails and the person has to be logged in to an email account. This could potentially cause delays for businesses if some one is not logged in or their computer breaks.
Also as email systems rely on the internet, if the internet goes down, possibly due to router problems or just a tempermental connection, people not be able to send or receive email. This can specific cause problems for businesses among the general public because it could mean important information could not be sent to meet the deadline.
Most email services have a limit on the file sizes of emails. Normally this limit is not exceeded because a lot of space is provided for users. However some services offer only a small limit. This can quickly get full. When that happens new emails can not be received and the email that went over the limit is usually incomplete. Someone might not receive an important email if this happemn.Emails have to be permanently deleted to make more space. This can take a lot of time and effort.
