Examples when to use informal writing?

Informal writing is appropriate in personal communications, such as emails or text messages to friends and family, where a casual tone fosters connection. It can also be effective in social media posts, blog entries, or creative writing, where a conversational style engages the audience. Informal writing may be used in brainstorming sessions or casual workplace communications to encourage open dialogue and creativity. Additionally, it suits contexts where humor or personality enhances the message.
