An Indian salesman sending Diwali wishes to his customers from his phone, with diyas beside him

Diwali wishes for customers you can copy: 40 short messages for insurance, loan and property agents and shops, and how to send them on WhatsApp.

Diwali is the one week every customer expects to hear from you, and the one week a simple wish can restart an old conversation. Here are 40 Diwali wishes for customers, ready to copy, sorted by what you sell. At the end you will see how to send them to your whole list on WhatsApp, each with the customer's own name. This year Diwali is on Sunday, 8 November, and Dhanteras is on Friday, 6 November.

Replace [Name] with the customer's name, and [Your Name] or [Your Business] with yours.

How to write a Diwali wish customers actually read

Three things make the difference:

  • Use their name. "Happy Diwali, Sunita ji" feels personal. A forwarded poster does not.
  • Wish first, sell later. Let the first message be only a wish. It earns you the reply.
  • Keep it short. Your customer will get 100 Diwali messages. Two lines get read.

Insurance agents: many insurers need their written approval for any advertisement, with the insurer's and agent's names in it. Check with your branch before you send a message about a product.

How to send Diwali wishes to all your customers on WhatsApp

You have three ways, and the right one depends on how many customers you have.

  • One by one, for your top 20 customers. Nothing beats a personal message. Add one line about them, like their new home or their child's admission.
  • A broadcast list, for customers who saved your number. It reaches up to 256 people per list, but the WhatsApp broadcast limit means anyone who has not saved your number gets nothing, and no one sees their own name.
  • The official WhatsApp Business API, for everyone else. You send one approved template to your whole list, and each customer sees their own name. Our guide to sending bulk messages on WhatsApp shows how.

A Diwali template ready to submit

On the API, your wish must be an approved template. In the template below, {{1}} is the customer's name and {{2}} is yours:

Dear {{1}}, warm Diwali wishes to you and your family from {{2}}. May the festival of lights bring health, happiness and prosperity to your home.

Three things to get right:

  • Choose the Marketing category. Meta treats greetings and offers as marketing.
  • Do not start or end the message with a {{1}}. Keep words before and after each one.
  • Submit at least a few days early. Approval usually takes minutes to a day, but template approval time can stretch, and festival week is the wrong time to be waiting.

Each marketing message costs about ₹1.02 with GST in India, so a wish to 100 customers costs about ₹102.

When to send Diwali wishes

We suggest the morning of Dhanteras, or the day before Diwali. On Diwali itself everyone sends at once, and yours gets buried. Meta also limits how many marketing messages one person receives from all businesses, so a customer who has already had many may not get yours. In one client's broadcast, 15 of 50 offers were held back this way. Sending early gives you a better chance.

Frequently asked questions

What is a good Diwali message for customers?

Short, with their name and a thank you. For example: "Happy Diwali, Sunita ji! Thank you for being with us this year. Wishing you and your family health, happiness and prosperity."

Should I add an offer to my Diwali wish?

Keep the first message a plain wish. Send an offer later, to the people who replied. A wish that ends in a sales pitch feels like an advertisement.

Can I send the same Diwali wish to everyone on WhatsApp?

Yes, with a broadcast list for people who saved your number, or with an approved template on the official API for everyone else. Avoid unofficial bulk sender apps: they can get your number restricted.

Should I send a poster or a text message?

A short text with their name usually does better than a poster, because a poster looks forwarded. If you want a picture, send it with a personal line.

How do I wish clients a Happy Diwali formally?

Use their name, thank them for their trust, and wish them and their team well. The formal wishes for clients above are written for that.

Send your Diwali wishes with each customer's name

Agniix sends your approved wish to your whole list on the official WhatsApp Business API, with each customer's own name, and shows you who replied, so you know who to call after the festival. It costs ₹500 a month, first month free, and Meta bills your messages directly. See how it works, or start your free month.
