How to Write an Email with Gemini

Gemini, Google's artificial intelligence, is a powerful tool for writing professional, commercial, or personal emails in seconds. Whether you need to send a job application, follow up with a client, or reply to a colleague, Gemini helps you structure your message, find the right tone, and save precious time. In this tutorial, you will learn step by step how to use Gemini to compose clear, impactful emails tailored to each situation. You will discover the most effective prompts, best practices for personalizing your messages, and mistakes to avoid to achieve a professional result from the very first try.

Prerequisites

1.Have a Google account to access Gemini (gemini.google.com)
2.Identify the recipient, subject, and main objective of your email
3.Know the desired tone (formal, friendly, commercial, etc.)

Steps

Define the context and objective of the email

Before using Gemini, mentally clarify the key elements of your email: who the recipient is, what the subject is, what outcome you expect (a reply, a meeting, approval), and what tone to adopt. The more precise you are in your brief, the more usable the result will be. Open Gemini in your browser and prepare to write a structured prompt.

Tip: Note these elements in a draft before passing them to Gemini to avoid forgetting anything.

Write a detailed prompt to generate the email

Give Gemini a prompt that contains all necessary information: the recipient, context, objective, tone, and key points to cover. A well-structured prompt yields an almost finalized email from the first generation, without needing multiple back-and-forths.

Write a professional email to [RECIPIENT_NAME], [JOB_TITLE], from company [COMPANY_NAME]. Context: [explain the situation]. Objective: [what you expect]. Tone: [formal/cordial/commercial]. Points to include: [point 1], [point 2], [point 3]. The email should be between 150 and 200 words, with a catchy subject line.

Tip: Replace each bracket with your actual information. The richer the context, the better the result.

Analyze and personalize the generated draft

Read the email proposed by Gemini carefully. Check that the tone matches your relationship with the recipient, that the factual information is correct, and that the structure is logical (hook, body, call to action, closing). Add personal details or specific references known only to you to make the message authentic.

Tip: An AI-generated email should always be reviewed and personalized. Add a reference to a past conversation or a personal detail to avoid the generic effect.

Ask for variations or adjust the tone

If the first result is not perfect, ask Gemini to modify the tone, length, or angle of the message. You can also ask for multiple versions to choose the best one. This step is especially useful for sensitive emails (follow-ups, negotiations, polite refusals).

Propose 3 variations of this email: a more direct and concise version, a warmer and more empathetic version, and a more formal version. Keep the same objective and key information.

Tip: For important emails, always generate at least two variations and combine the best elements from each.

Finalize, check, and send the email

Read the final version one last time. Check spelling, grammar, proper nouns, and figures. Make sure the subject line is clear and compelling. Copy the text into your email client (Gmail, Outlook, etc.), attach necessary files, and send. If using Gmail, you can also access Gemini directly from the compose interface.

Proofread this email and correct any grammar, spelling, or syntax errors. Check that the tone is consistent from start to finish and that the call to action is clear.

Tip: Use the 'Help me write' feature built into Gmail to refine directly in your inbox without leaving the interface.

Common mistakes to avoid

✗Writing a too vague prompt (e.g., 'write an email') without specifying the recipient, context, or tone, which yields a generic and unusable result
✗Copy-pasting Gemini's result without proofreading or personalizing, leading to an impersonal email that the recipient will identify as AI-generated
✗Forgetting to verify factual information (names, dates, numbers) that Gemini may invent or approximate
✗Neglecting the email subject line, which is still the determining factor for open rate
✗Using a tone inappropriate for the relationship with the recipient due to lack of precision in the initial prompt

FAQ

Can Gemini write emails directly in Gmail?

Yes, if you have a Google Workspace subscription with Gemini enabled, you can use the 'Help me write' feature directly in Gmail's compose interface. For the free version, you can generate the email on gemini.google.com and then copy it into your email client.

How do I get an email that doesn't look like AI-generated text?

The key is to provide a highly contextualized prompt with specific details (names, references to past exchanges, precise data), then personalize the result by adding your personal touch. Also ask Gemini to adopt a conversational rather than formal style for a more natural output.

Is Gemini suitable for confidential or sensitive emails?

Gemini processes your data according to Google's privacy policy. For emails containing highly sensitive information (financial, medical, legal data), avoid including confidential details in your prompts. Use generic terms in the prompt, then manually add sensitive information in the final version.

Can I use Gemini to write emails in multiple languages?

Absolutely. Gemini handles many languages. Simply specify the desired language in your prompt (e.g., 'Write this email in professional English'). You can even ask it to translate an existing email while adapting politeness formulas to the cultural conventions of the target country.
