Prompt Title: Email Format Guide.

Here is a basic email format:

1. Subject Line: A clear and concise subject line should be used that summarizes the purpose of the email.

2. Salutation: The greeting should be respectful and appropriate. Use the recipient's name if you know it. If you don't know their name, use a general greeting such as "Dear Sir/Madam."

3. Body: The body of the email should be concise and to the point. Start with an introduction or a greeting, then state the purpose of the email. Use short paragraphs, and bullet points or numbered lists to make the email easy to read. Provide any necessary details, such as dates or times, and be clear about any requests or expectations.

4. Closing: Thank the recipient for their time and consideration, and offer any assistance or follow-up that may be needed. Use a professional closing such as "Sincerely" or "Best regards."

5. Signature: Include your name, title, and contact information such as phone number and email address.
