To customers — warm and short
Two lines is plenty. The value is in being remembered, not in being read carefully.
A festival message from a business is read differently from a campaign, and it is worth protecting that. The greetings below lead with the wish rather than the offer, because a Diwali message that turns out to be a coupon is remembered as one — and remembered next year too. Where an offer genuinely belongs, it goes at the end and stays small.

Two lines is plenty. The value is in being remembered, not in being read carefully.
Name the relationship rather than the transaction. A B2B Diwali message that reads like a sales email defeats itself.
Say what they actually did. A generic festival message to your own team is worse than none.
The wish comes first and the offer stays one line. If the message reads as an advert with a greeting attached, send it as a campaign instead and leave the festival message clean.
Send these separately from the greeting, and early enough to be useful.

A short, warm wish that names nothing you are selling. Two or three lines, sent on the day or the evening before. If you genuinely have a festive offer, put it on one line at the end — or better, send it as a separate campaign and keep the greeting clean.
Usually not. A festival greeting that turns out to be a coupon is read as an advert and remembered that way, including next year. If the offer matters, send it as its own marketing message and let the greeting do the job it is good at, which is being remembered warmly.
Yes, if your business is starting the conversation on the WhatsApp Business Platform — a greeting is a business-initiated message like any other. And if it carries an offer it is a Marketing template rather than Utility, with the higher rate and the opt-in requirement that go with that.
No. There is no festival exemption from an opt-out, and sending one is the kind of thing that produces the reports that damage your quality rating. If someone said stop, a greeting is still a message.
On the day itself or the evening before. Sending a week early to get ahead of the rush is the most common mistake — it arrives before anyone is thinking about the festival and lands as a marketing message, which is exactly what you were trying to avoid.
