Send a short, personal Diwali message to the clients who know you, over the channel you already use with them, a few days early. Don't blast the whole client list, don't attach a pitch or a payment reminder, and check a client's gift rules before anything arrives in a box.
The message itself is the easy part, and the Diwali wishes for clients page has lines for it. This is about the decisions around the message: who gets one, how it gets there, and what to leave out.
Who should get one
Not everyone on the list. A Diwali email to every contact, including people who have never mentioned the festival, reads as a mail merge and tells the client you don't know who they are. Sort the list by how well you know them.
- Clients you speak to regularly. A personal message from you, by name, with one detail only you would know.
- Your biggest accounts. A call, a printed card or a small gift, with a personal note as well. These are the clients most likely to remember who made the effort.
- Dormant or one-off clients. Usually nothing, or a general festive-season note. A warm Diwali message from someone they haven't heard from in a year can feel more like a sales opener than a greeting.
- Prospects. No. A festival greeting is not an introduction.
For clients who aren't Hindu, or who are abroad, wish them if they've mentioned the festival or celebrated with your team. If you don't know, a general line about the festive season is safer than assuming. The corporate wishes page covers mixed teams in more detail.
Which channel to use
Use the one the client already uses to reach you. A greeting that arrives somewhere unexpected feels like a campaign.
- WhatsApp. Best for clients you already message there. Write to each person. A broadcast list only reaches people who have saved your number, and it arrives looking like a personal chat, so it only works if it reads like one.
- Email. Better for formal relationships, for clients who only ever email you, and for clients abroad. Send it from a person, not a shared inbox.
- A call or a card. For your top few. A handwritten card on a client's desk lasts through the week, and an email doesn't.
- A LinkedIn post. Fine for the public, but it isn't a greeting to a client. They still need their own message.
Gifts
Sweets and dry fruits are the usual choice in India, and a small box is easier to accept than anything with a price tag. Two things matter more than what's in it.
- Check the client's gift policy. Many companies cap or ban gifts from vendors, and public-sector and regulated clients are often the strictest. If you don't know the rule, ask the client's assistant, or skip the gift and send a card.
- Mind the timing. Send it so it arrives before Dhanteras, which in 2026 is Friday 6 November. A gift that turns up after Diwali has lost its point.
- Keep it safe. Vegetarian, and no alcohol unless you know the client well. If you can't tell, the card matters more than the box.
What to leave out
- A pitch. "Happy Diwali, and here is our festive offer" is an advertisement wearing a greeting. If you have an offer, send it separately.
- A payment reminder or an ask. Never in the same message. If an invoice is overdue, send that on a different day.
- A forwarded image. A glittering deity from a family group chat doesn't say anything about the client. Write your own line.
- Religious language you wouldn't use in person. Wish them well. You don't need to bless their business.
When to send
A few days early, not on the day. In 2026 the main day is Sunday 8 November, so the week of 2 November is right. The wishes page has the reasoning, and it's the same for every client: on the day itself, their inbox is full and they're with family.
If they reply, or you forgot
If a client writes first, answer the same day, on the same channel, in about the same length. One warm line is enough. Don't turn it into a meeting request.
If you forgot, send it within the week and don't apologise for a paragraph. A late wish still counts, and "Belated Diwali wishes" is a perfectly good opening.
After Diwali
If a client sent a gift, thank them in a line. Then leave it. The next greeting is the New Year, and the relationship does the rest in between.
