Asking for help and advice

Formal emails are used when the writer is asking advice from someone outside their company, someone they don’t know very well, or someone they consider to be more senior to them. Informal emails asking for advice would most likely be sent to colleagues at a similar level in the company, or to people the writer knows relatively well.
