What is WhatsApp marketing?
WhatsApp marketing is a conversation, not a billboard. A customer gives you their number and permission, you send something genuinely useful — a restock, an offer, a delivery update — and they can answer in the same thread the way they would answer a friend.
That is the difference from email or SMS blasts. Every message you send can be replied to, and most people do reply, which means the channel only works if someone is ready to answer. The businesses that do well on WhatsApp treat it as a shopfront that talks back.
Because it is people’s personal messaging app, the rules are stricter. You need recorded opt-in, your first message has to use a template Meta has approved, and sending too often gets you blocked and reported. Get those right and open rates sit around 98%. Get them wrong and you lose the number.

Features of our WhatsApp marketing services
Everything needed to run a campaign end to end, from one panel your marketing team can use without opening a ticket.
Images, video, PDFs and catalogues
Attach a product shot, a 30-second demo, a price list or your full catalogue. Media is hosted, compressed and cached, so the same file sent to 50,000 people uploads once.
Schedule campaigns properly
Pick a send time in each recipient’s timezone, set quiet hours, and cap how often one person can hear from you. Campaigns queue rather than fail when they hit the edge of a window.
Auto chatbot replies
Answer the questions that arrive after every campaign — price, size, stock, delivery time — from your own product data. Anything it cannot answer goes to a person with the thread attached.
Buttons, lists and quick replies
Give people something to tap instead of something to type. Call-to-action buttons open your site or dial your number; quick replies capture intent as structured data you can segment on later.
Built-in API and webhooks
Trigger messages from your own backend with a REST call, and receive signed delivery, read and reply events. SDKs for Node, Python, PHP and Java, with sandbox keys before you talk to sales.
What WhatsApp marketing can do for your business
Numbers from campaigns we run for retail, education and services clients. Yours will differ, but the shape rarely does.
98%
Open rate
Messages are read on the lock screen, usually within minutes of arriving. Email struggles to reach a quarter of that.
3 min
Median time to read
A campaign sent at 10am has done most of its work by 10:05, so you learn whether the offer landed the same morning.
2–3×
Click rate versus SMS
Tappable buttons and a recognisable verified sender do most of that work. No shortened links people distrust.
8–14%
Carts recovered
One reminder about an hour after checkout is abandoned, with the items still in the basket and a link back.
60%
Replies handled by bot
The routine questions never reach your team, so a campaign to 50,000 people does not need five extra staff.
1,000
Free service conversations
Customer-initiated conversations each month cost nothing, which makes replies the cheapest part of the channel.
Our WhatsApp marketing services will help you
Six campaigns worth building first. Most clients run all of them within the first quarter.
Reach new audiences
Turn ad clicks into conversations with click-to-WhatsApp campaigns, and turn shop footfall into a contact list with QR codes that start a chat rather than open a form.
Improve conversions
Answer the question standing between someone and a purchase — size, stock, delivery date, warranty — in the moment they ask it, with a link straight to checkout.
Send personalised messages
Merge name, last purchase, city, language and loyalty tier into the template. One campaign, thousands of versions, no spreadsheet gymnastics.
Recover abandoned carts
Trigger about an hour after checkout is left, showing the exact items still in the basket. Escalate to a discount only on the second message, and stop the instant the order lands.
Native and custom integrations
Shopify, WooCommerce, Salesforce, HubSpot, Zoho and Google Sheets out of the box. Anything else through the API, webhooks or Zapier.
Re-engage quiet customers
Find everyone who bought once and never came back, and give them a reason to return that respects how long it has been. Suppressed automatically if they order in the meantime.

FAQs
Most start with three campaigns: an offer broadcast to opted-in customers, an abandoned cart reminder about an hour after checkout is left, and a re-engagement message to buyers who have gone quiet for 90 days. Each is an approved template with buttons, and every reply lands in a shared inbox where a person can take over.
Marketing templates promote something — offers, launches, reminders to buy — and need clear opt-in. Utility templates follow up on an action the customer already took, like an order confirmation or delivery update. Meta prices the two differently and reviews marketing templates more strictly, so keeping them separate protects both your costs and your approval rate.
Two parts: our platform fee, and Meta’s per-conversation charge, which varies by country and template category — India sits at the low end, the United States at the high end. Customer-initiated service conversations are free for the first 1,000 each month, so campaigns that generate replies are usually cheaper per outcome than they first appear. We pass Meta’s fee through at cost and itemise it.
Yes. WhatsApp requires recorded opt-in before any business-initiated message. We store the timestamp, source and exact wording each contact agreed to, and block campaigns to numbers without a valid record. Sending to a scraped or purchased list is the fastest way to lose a number.
Not if you send to people who asked to hear from you. Quality rating is driven by blocks and reports, so we cap frequency per contact, watch the rating hourly, and pause a campaign automatically if it drops to medium. Running on the official platform with a verified sender also means a bad week costs you a rating, not the account.
A test sender is live in about an hour. Business verification with Meta takes one to three days, and each template is reviewed in anywhere from a few minutes to 24 hours. Most clients run their first real campaign within a week.
