To begin a formal email, you should follow these guidelines:

  1. Start with a formal greeting: Begin with "Dear" followed by the person's title and last name, such as "Dear Mr. Smith" or "Dear Dr. Johnson."

  2. Use a polite opening: Depending on the context and purpose of the email, you may want to start with a brief sentence that sets a polite and respectful tone, such as "I hope this email finds you well" or "Thank you for taking the time to read my message."

  3. State the purpose clearly: In the first paragraph, clearly state the reason for your email and what you hope to achieve. This will help the recipient understand the context of your message and respond appropriately.

  4. Provide necessary details: If your email requires specific details or information, make sure to include them in a clear and concise manner.

  5. Close with a polite conclusion: End your email with a polite and respectful closing, such as "Thank you for your time and consideration" or "I look forward to hearing from you soon."

  6. Use a formal signature: Use a formal signature that includes your full name, job title (if relevant), and contact information.

Overall, it's important to be clear, concise, and professional in your email, while also being polite and respectful.
