WhatsApp marketing for restaurants in India

WhatsApp marketing works for Indian restaurants, but only to customers who agreed to hear from you. Under India's Digital Personal Data Protection Act, 2023 (DPDP), consent for promotions must be a clear, specific "yes" — a phone number given for a delivery is not permission to send offers. Get the opt-in right and WhatsApp is cheaper and far more likely to be read than SMS: a marketing message to a +91 number costs ₹0.8631 on Meta's INR card, promotions land in the app your customers already use, and you skip the DLT template approvals that SMS needs.

Step 1: Collect consent the DPDP way

The DPDP Act (Section 6) says consent must be free, specific, informed, unconditional and unambiguous, given by a clear affirmative action. For a restaurant that means:

• Ask separately for marketing. A checkout or a QR order that captures a number for the order is not consent to promote. Add a distinct, unticked opt-in: "Send me offers on WhatsApp."
• Say what they're signing up for — offers, new dishes, festival menus — in plain words, not buried in terms and conditions.
• No pre-ticked boxes, no "agree to everything." Consent for promotions has to be its own choice.
• Keep a record of who opted in and when.

Step 2: Send promotions as marketing templates

Broadcasts and offers go out as marketing templates, which Meta approves before use. On Meta's INR rate card, a marketing message to a +91 number costs ₹0.8631, with 18% GST added on your Meta invoice. Order updates (placed, dispatched, delivered) go out as utility templates at ₹0.115 and need no marketing consent — keep the two streams apart. See the full rate card in WhatsApp Business API pricing in India.

Step 3: Make opt-out as easy as opt-in

The Act says withdrawing consent should be as easy as giving it. In practice:

• Put a "Stop promotions" quick reply on your broadcasts, or a clear "Reply STOP to opt out" line.
• Act on it promptly in your system, so the customer stops getting offers.
• Never stop their order updates because they opted out of marketing — those are a different purpose.

WhatsApp vs DLT-registered SMS

Promotional SMS in India runs on TRAI's DLT (Distributed Ledger Technology) regime. Every sender has to register the business, a 6-character header and each content template on a DLT portal before a single message goes out. Here is how the two channels compare for a restaurant:

Both channels need DPDP consent. WhatsApp wins on format, timing and engagement; SMS still reaches feature phones and customers who don't use WhatsApp. Many restaurants use WhatsApp for marketing and keep SMS only for one-time passwords.

Worked example: one promotion a month

A kitchen broadcasts one festival offer a month to 1,500 opted-in customers:

• 1,500 × ₹0.8631 = ₹1,294.65 before GST (about ₹1,527.69 with 18% GST).

That is the whole cost of reaching 1,500 regulars directly. Model your own numbers in the WhatsApp cost calculator.

Good practice for restaurants

• Broadcast rarely and relevantly. One strong offer beats weekly spam; over-messaging drives opt-outs.
• Segment. Send a biryani offer to people who ordered biryani, not your whole list.
• Tie it to ordering. A promotion with a one-tap link back to your WhatsApp ordering or ordering page turns a message into a sale.
• Never buy lists. Messaging people who never opted in breaches both Meta's rules and DPDP consent.
