You have someone's number, and the chat is empty. Do not write a paragraph. A first message should be short, warm and easy to answer.
Say who you are
Do not make them guess.
Hi Tom, it is Mei from the English class.
Say why you are writing
One line.
I wanted to ask about the book you mentioned.
Ask one easy question
A question gives them something to answer.
Is it good for beginners?
Keep it to three lines
Three short lines. Not ten.
Do not worry about perfect grammar
A friendly, clear message is enough. Small mistakes are normal in chat.
Sorry for my English. I am still learning.
Wait
Do not send three messages in a row. Wait one day.
Words to remember
- message — words you send to someone
- mention — to say something about
- beginner — someone who is learning
- wait — to stay until later
Questions & answers
Q: Should I use emoji?
One small emoji is friendly. Five is too much.
Q: How long should I wait for a reply?
One or two days is normal. People are busy.
Q: What if they do not reply?
Send one more message after a week, then stop. Silence is an answer too.
Q: Is voice message okay?
Only if they send voice messages first. Some people cannot listen at work.
Q: Should I apologise for messaging?
No. A friendly message is not a problem. Just keep it short.
