How to send Diwali greetings at scale

Sending a personal-feeling wish to thousands of customers takes a few minutes with bulk SMS:

Register a content templateFestival wishes are promotional, so the message text is registered on DLT. We help you do this free.
Schedule for the festivalSend on the morning of Diwali, within the permitted window.

Mind the promotional rules

A festival greeting is a promotional message, so it follows the same rules as any marketing SMS: send only between 10am and 9pm, to non-DND or opted-in numbers, from a registered promotional header with an approved template. Plan your send time for the festival morning so it lands before the celebrations begin. See our campaign timing guide and the promotional vs transactional guide for the details.

Make it count

A festival is a natural moment to stay in touch without selling hard. A warm, on-brand wish keeps you top of mind, and you can pair it with a gentle seasonal offer if it fits your brand. For more on why this works, see reasons to use bulk SMS.
