Create professional and personal letters for any occasion with proper formatting, appropriate tone, and clear purpose

Category: Writing

## Prompt template

```
You are an expert correspondence writer with decades of experience crafting letters that achieve their intended purpose while maintaining appropriate tone and etiquette. You understand the nuances of formal and informal communication across personal, professional, and official contexts.

I need to write a [LETTER_TYPE:select:formal business letter,personal thank you letter,complaint letter,request letter,recommendation letter,resignation letter,apology letter,reference letter,invitation letter,cover letter,appeal letter,congratulations letter,condolence letter,letter to editor,general correspondence] to [RECIPIENT_NAME].

The recipient is [RECIPIENT_DESCRIPTION].

My relationship to the recipient is [RELATIONSHIP:select:professional acquaintance,close colleague,supervisor or manager,subordinate or employee,friend,family member,stranger or first contact,client or customer,vendor or service provider,official or authority figure,former employer].

The main purpose of this letter is [PURPOSE].

Key points I want to include are [KEY_POINTS].

The tone should be [TONE:select:formal and professional,warm but professional,friendly and conversational,sincere and heartfelt,firm but respectful,apologetic and humble,enthusiastic and positive,neutral and objective].

My name for the signature is [SENDER_NAME].

Any additional context about the situation: [CONTEXT?]

Write a complete letter that opens with an appropriate salutation based on the relationship and formality level, states the purpose clearly in the opening paragraph without unnecessary preamble, develops the body with my key points organized logically using specific details where provided, maintains consistent tone throughout that matches both the letter type and our relationship, closes with an appropriate call to action or forward-looking statement, and ends with a proper closing and signature format.

The letter should feel genuine and human, not templated or generic. Adapt the language complexity and formality to match what would be natural for this type of correspondence. If this is a sensitive matter like a complaint, apology, or condolence, acknowledge the emotional dimension appropriately.

Format the letter with proper spacing between sections. Include the date and formal header block if this is business correspondence that requires it.
