Description:

Grammarly How to Write Polished, Professional Emails With AI explains how to get a usable email draft out of an AI assistant and what to change before it goes out. The guide defines an AI email, names the parts people most often want help with, among them openings, closings, bad news and a cold introduction, and shows a one-line prompt beside a detailed one so the difference in the answer is visible.

100% Free (unlimited): Reading the full guide is free and needs no account: the definition of an AI email, the two prompt examples with the detail that separates them, the instruction for asking for a subject line, the sections on work and personal email, and the frequently asked questions are all on the page.

How It Helps Your Business English

What this resource offers:

The guide defines an AI email, then builds a prompt: a one-line version confirming an appointment, and a detailed version carrying the time, the facts to include, the tone and the urgency. Short instructions follow for asking for a subject line and for keeping every detail in one message. Sections on work email and on personal email close with etiquette points and an FAQ.

How to use this resource:

You can write a better prompt on your first try: name the recipient, the purpose, the facts to include, the tone and the length, and ask for a subject line in the same message. Compare the two example prompts to see how much the extra detail changes the answer. Then do what the guide asks, and reword the draft in your own phrasing and check it before sending, for facts as well as grammar.
