How to write a great informal email or message.

We often talk about semi formal and formal writing but seldom informal. So here are some do’s and don’ts to keep in mind when writing an informal email, message or text

Do use idiomatic language, example raining cats and dogs
Do use colloquial vocabulary for objects, places, feelings.
Do use everyday adverbs, linkers etc, example but, also
Do use present tenses to keep your writing direct.
Do use past simple and past perfect to sequence a timeline of actions.
Do use paragraphs.
Do use contractions.
Do begin with Hi, and end with Bye!

Don’t use slang words, example innit, gunna. Though words like yeh, hi, nah are fine.
Don’t write overly long sentences with lots of commas.
