WhatsApp marketing for electronics stores: rules, a campaign plan and costs

Meta allows promotional messages only to people who agreed to receive them, only as approved marketing templates, and only with an easy way to stop. For an electronics store the practical question is where consent comes from. Purchase and service drop-off are the moments — both come with an obvious reason to send updates. A number printed on an invoice is not consent.

Customers give their number for the invoice and warranty. Ask separately whether they want launch and offer news, and record it. Warranty and service messages go to all customers; campaigns only to those who agreed.

Build campaigns on moments that already happen in your customer's relationship with you, not on a calendar of generic promotions. Launches, exchange offers and accessory follow-ups for customers who bought the matching device.

In practice, for an electronics store:

1. Post-purchase setup guide on WhatsApp — After purchase, send product setup guide, troubleshooting tips, and how-to links. (utility template)
2. Warranty expiry alert at 11 months — 30-day warning before warranty expiry with free service check offer and renewal option. (marketing template)
3. New model launch notification to relevant buyers — When a new iPhone/Samsung/TV model launches, notify buyers of the previous gen with upgrade offer. (marketing template)
4. Annual service reminder sent automatically — Every 12 months, automated service reminder for ACs, refrigerators, and smart appliances. (utility template)

Service updates as the repair moves, warranty-expiry reminders, and launch messages when a new model arrives. Half of this plan is not "marketing" in Meta's sense. Confirmations and updates are utility messages — cheaper, and they build the trust the promotional ones depend on.

Meta charges each delivered marketing message. A campaign to 1,000 opted-in customers in India costs about ₹863 plus GST in Meta fees; the same send elsewhere:

Reputoo does not add a per-message markup; you pay Meta's rate and your plan.

A customer who bought a phone three years ago is a likely upgrader. A launch message with an exchange offer for their model — "your Galaxy S21 could be worth up to ₹X in exchange" — is relevant in a way a broadcast is not. Purchase history makes this possible.

A new laptop owner needs a bag and a mouse; a new TV owner might want a soundbar. One message a few days after purchase with accessories that fit their device is helpful, not pushy.

These are the problems electronics stores are usually trying to fix with WhatsApp:

• Warranty expiry not tracked, customers not alerted. Customer bought a TV 11 months ago. Warranty expires next month. Nobody told them. They pay for repairs that would have been free.
• Support call volume is high for common queries. "How do I connect Bluetooth?" "Why is the screen dim?" WhatsApp chatbot answers these without involving your staff.
• New product launches reach existing buyers too late. iPhone 16 launches. Your existing buyers find out from an ad. You should have been first to tell them with a personalised offer.

A broadcast fixes none of them on its own. Segment first — recent customers, lapsed ones, people who asked about a specific thing — and send each group the one message that matters to it. Smaller, relevant sends get more replies and fewer blocks than one big blast.

Reads show a message arrived; replies, bookings and orders show it worked. Reputoo attributes revenue to the campaign that brought each customer back, so you can drop the sends that only produce reads.

Before a product's warranty expires, a message offering extended warranty — with what it covers and the price — reaches the customer at the only moment it matters. Send it once.

(Model and values are an example.)

At ₹0.8631 per marketing message on Meta's July 1, 2026 India rate card, a launch message to 2,000 opted-in customers costs ₹1,726, plus GST. One phone sale covers it many times.

Launches, a few seasonal campaigns and personal upgrade offers — not daily deals. Electronics customers buy rarely; a message every week trains them to ignore you.

Count pre-bookings, exchanges and sales from each campaign. Reputoo attributes them to the message that prompted them.

• Phone owners by model age.
• Appliance owners by product and warranty date.
• Laptop and tablet buyers — students and professionals.
• Service customers — may be ready to replace a device that keeps failing.

A customer whose phone has been repaired twice this year may be ready for a new one. A thoughtful message after the second repair — with trade-in value for their device — is a service, not a pushy sale. Send it once.

Offices refresh laptops on cycles. A message to past corporate buyers before financial-year end and new-hire seasons, with bulk pricing and delivery options, reaches buyers who purchase dozens at once.

Send offers only to opted-in customers, and match each to what they own. Blocks lower your quality rating, which can limit service and delivery messages — the ones customers most need.

Show the actual product, the key spec that matters to the segment (camera for phone buyers, battery for laptop buyers) and the final price with offers. Clear, honest specs beat superlatives.

Customers who pre-registered interest in a launch want to know the moment stock arrives. An alert to them only, with the model, colours available and a hold button, converts far better than a general announcement.

AC and cooler demand depends on the local summer; heater and geyser demand on the winter. Time appliance campaigns to your region's weather and send them to customers who own older units, when the need is real.

A gaming weekend, a home-theatre demo evening or a camera workshop brings enthusiasts in. Invite customers whose purchases fit, a week ahead, with an RSVP button.

Electronics margins are thin. Measure each campaign by margin earned, not revenue — an accessories campaign may earn more than a phone campaign with deep discounts.

State the final price including the offer, the exact exchange value range and any conditions. Customers compare prices online in seconds; a message that turns out to be less generous than it looked loses them for good.

A customer who bought a TV and a phone from you and nothing for two years is not lost — they simply had no need. One message when their devices reach replacement age, with an exchange offer, brings them back at the right moment.

Screen protectors when a phone is bought, a soundbar a week after a TV, a laptop bag at back-to-school — accessories sell when they match a recent purchase. Keep these to one message per purchase.

Free check-up camps for ACs before summer or for washing machines before festivals bring owners in, and many book paid servicing or upgrade. Announce them to owners of those appliances with a date and a booking button.

Send offers in the evening and at weekends, when customers compare prices; launch alerts the moment stock arrives. Avoid late nights.

A first-time buyer gets one message after purchase with setup help, the warranty details and how to reach service — and, if they opted in, a note that they will hear about launches for their device. It sets up the relationship for the next purchase.

Avoid daily flash deals, prices that exclude conditions, and messages about products the customer has no reason to want. They cost quality rating and trust, and electronics customers have many other places to buy.

Before a launch, invite customers who own older models to register interest. The list tells you how much stock to order and who to alert first on launch day.

Record who agreed to offers, when and how. When a customer opts out, keep their warranty and service messages running — those protect a purchase they already made — and stop the offers immediately.

Bundles — a phone with earbuds, a TV with a soundbar, a laptop with a printer for students — work well before festivals and back-to-school. Show the bundle price against buying separately, honestly, and send it to customers whose history fits.

Look at each week's campaigns together: what was sent, to whom, what sold, and what was returned. Patterns appear quickly — which segments respond to launches, which only to exchange offers — and next month's campaigns get sharper.
