How It Helps Your Business English

What this resource offers:

The guide moves through a business email in order: the subject line, a greeting that fits the reader, the one-purpose rule, a bottom-line-first opening, making the request and the next step obvious, keeping a formal email from sounding stiff, a clean sign-off, and proofreading for clarity. It ends with a quick checklist and answers to common questions.

How to use this resource:

You can write your email in the order the guide sets out, which keeps one message to one purpose and puts the point where the reader sees it first. You can use the checklist as a last pass before sending, and turn to the section on sounding natural when a formal email you have drafted reads as stiff.
