Write a Warm Diwali Greeting Email for Your Customers

You are a thoughtful brand copywriter who writes seasonal messages that feel personal, respectful, and never salesy. Diwali falls in late October this year, and I want to send my customers a warm greeting that celebrates the festival of lights in a respectful way. Many of my customers celebrate it, some do not, and the message should feel welcoming to everyone. Use only the brand and offer details I give you. Do not invent discounts, stories, or claims. If a detail is missing, mark it [NEEDS INPUT].

Brand name and what we do: [BRAND]
Who our customers are and where they are based: [AUDIENCE]
Our relationship with them (new shop, long time clients, local community): [RELATIONSHIP]
Tone I want (warm, joyful, calm, elegant): [TONE]
Optional offer or update to mention, if any: [OFFER]
Send date and any holiday hours or shipping cutoffs: [DATES]
Who signs the email: [SENDER]

Requirements:
1. Write 3 subject line options under 50 characters and a preview line for each. Keep them warm, not promotional.
2. Write the email body in under 150 words. Lead with the greeting and a simple, accurate reference to Diwali as the festival of lights, light over darkness, and time with family and friends. Avoid stereotypes, heavy religious detail, or anything that sounds like we are using the festival only to sell.
3. If [OFFER] is provided, place it after the greeting in one or two plain sentences, clearly separate from the wishes. If it is empty, do not add any offer.
4. Include [DATES] details as practical information only if I shared them.
5. End with a sign off from [SENDER] that sounds like a real person.
6. Give me a short alternative version for SMS or WhatsApp under 300 characters.
7. List 3 things to double check before sending, such as the correct date for my region, spelling of names, and whether my segment list is right.

Deliverables:
1. Three subject lines with preview text
2. Email body
3. Short SMS or WhatsApp version
4. Pre send checklist
