The differences in memos in my opinion are :
– Memo is a form of letter without a letterhead or written message which is usually used in the internal environment of an organization, whose purpose is positive such as telling good
news. Memos are usually intended for internal communication within an
organization and memos are not used to announce news that is not true. good or bad. For example, reporting sad news, so it is usually used to report official messages
and important issues. Whereas
– Email or electronic mail is an electronic message that can be sent via the internet to a person or recipient quickly, email is also a means of sending letters via a computer network or
cellphone, email is also an official address in cyberspace. There are many functions of email, such as sending files, photos, videos and so on, more precisely, when looking for work, this can make things easier for someone and many people. Meanwhile, email can be used for two things, namely internal and external to the organization.
In conclusion, the difference between memos and emails is that memos tend to be more formal and structured while emails tend to be more flexible and can be adjusted to suit an individual's (person's) communication style.
