Does replying to WhatsApp enquiries break PDPA or the Do Not Call rules?

Answering someone who messaged you first is a different thing from cold-blasting a list of numbers. Under Singapore's Personal Data Protection Act, marketing messages need consent, and the Do Not Call Registry covers telemarketing to Singapore numbers. Responding to an enquiry the buyer started, on the channel they chose, sits in a different place from unsolicited outreach. This is not legal advice, so confirm how consent and DNC apply to your own setup before you switch anything on.

Will customers know they are chatting with an assistant?

You can set the tone however you like, and being upfront tends to build trust rather than lose it. What buyers actually care about is a fast, correct answer and a real slot, not whether a human typed the first reply at midnight. The moment a chat needs a person, it hands off to your team.

I already have a WhatsApp button. Do I need to change anything?

If your button opens the free WhatsApp Business app on one staff phone, it only works when that person is free and awake, and nothing gets logged. Moving to the WhatsApp Business API keeps the same familiar chat for your buyer while putting a system behind it: always on, shared across your team, and connected to your CRM.

What happens to enquiries that come in after hours?

That is where most of the loss happens today, and where this helps most. The assistant answers at 11pm or on a Sunday, qualifies the buyer, and books the slot, so the enquiry you would have seen tomorrow is handled tonight. If enquiries are reaching you and going cold before you can reply, the first fix is to close the timing gap on the channel your buyers already use. Start with the WhatsApp Business API in Singapore and see what answering in seconds does to your bookings.
