Prerequisites

1.Have an account on chat.mistral.ai or access to the Mistral API
2.Know your email context: recipient, subject, desired tone
3.Have the key information to include in the message (names, dates, specific details)

Steps

Define the email type and context

Before asking Mistral, precisely identify the type of email you want to write: professional, commercial, application, follow-up, complaint, or personal. Mentally clarify the recipient, the expected level of formality, and the main purpose of the message. This preparatory step is essential to formulate an effective prompt and get a relevant result on the first try.

Tip: Write down a few keywords covering the essential points to address before drafting your prompt. The clearer your brief, the better the result.

Write a precise and structured prompt

Open chat.mistral.ai and write a prompt that clearly describes your need. Include the email type, recipient, desired tone, key information to include, and approximate length. A well-constructed prompt avoids back-and-forth and produces an immediately usable email.

Write a professional email to my manager requesting 3 days of leave from April 21 to 23. Tone: polite and concise. Mention that my ongoing tasks will be handed over to my colleague Thomas. End with a standard closing.

Tip: Always specify the tone (formal, friendly, direct) and desired length to avoid an email that is too long or too short.

Analyze and adjust the first result

Read the email generated by Mistral carefully. Check that the tone matches your expectations, all important information is present, and the structure is logical (subject line, salutation, body, conclusion, signature). If certain passages are not suitable, request targeted adjustments rather than starting over.

Rephrase the second paragraph to be more direct and add a sentence mentioning that I remain reachable by phone in case of emergency.

Tip: Treat Mistral like an assistant: give it specific feedback rather than just saying "start over."

Personalize and humanize the message

The email generated by Mistral is a solid foundation, but it benefits from personalization. Add specific details that only you know: a reference to a recent conversation, a contextual detail, or a personal touch. Re-read the entire message to ensure it sounds natural and reflects your way of communicating.

Adapt this email to start by referencing our meeting last Monday where we discussed team leave planning.

Tip: A too-generic email is easy to spot. Always add at least one personal or contextual element to make the message feel authentic.

Generate the subject line and finalize sending

Ask Mistral to propose several impactful and relevant subject lines for the email content. A good subject line significantly increases the open rate and immediately gives the recipient context. Choose the clearest subject line, copy the final email into your email client, do a final proofread, and send.

Propose 5 short and professional email subject lines for this leave request email.

Tip: The ideal subject line is under 50 characters and clearly states the topic. Avoid vague subjects like "Request" or "Information."

Common mistakes to avoid

✗Writing a too vague prompt like "write an email" without specifying context, recipient, or desired tone
✗Copying and pasting the generated email without proofreading or personalizing it, resulting in an impersonal and sometimes inappropriate message
✗Not specifying the level of formality, which may produce an email that is too casual for a professional context or too rigid for a colleague-to-colleague exchange
✗Forgetting to check factual information (dates, names, figures) that Mistral might have misinterpreted
✗Requesting an email that is too long when a short, direct message would be more effective for the recipient
