Tips on writing formal and informal letters and emails

Confused about how to get started when you’re writing a letter? Do you know the differences between how formal and informal letters begin? Here are some tips:


  1. Don’t usually mention people’s first names in the greeting

    If you’re not sure who you’re writing to, you can use ‘To whom it may concern’. If you do know the recipient’s surname, as in ‘Dear Mr Wong’, feel free to use this.

  2. Use formal language to say exactly why you’re writing, usually right at the start

    If you are complaining about something, for example, you could use ‘I am writing to complain about…’. 

    For an invitation letter, you could use ‘Our company is delighted to invite you to…’. 

    Something like ‘We are pleased to inform you that we have approved your application for…’ would work when you’re writing an application approval letter.


  1. Use a first name or nickname to sound warm and friendly

    For example: ‘Hi Grandma!’, ‘Dear Siu Ming,’, or ‘Michael,’.

  2. Start with a greeting or a polite question about the reader before getting to the main ideas

    Instead of only using ‘How are you?’ at the beginning, have a look at these examples, all of which engage more fully with the reader:

    ‘I hope you’re well. How are the cats? Has Bella had her kittens yet?... Anyway, I’m writing to ask whether or not you’re free this summer…’

    ‘Hi! I’m sorry it’s been so long since I last wrote – school has been really busy! … I just wanted to find out if you’re still interested in the camping trip…’

    ‘How are you? I haven’t heard from you in a while so I thought I’d let you know how I’m getting on in Australia. … Tell me what’s happening with you! How’s your internship at the biomedical company going?...’
