Email open rates average 20%. SMS and WhatsApp open rates average 98%. If you're not using these channels, you're leaving your highest-converting touchpoints completely untapped. SMS and WhatsApp marketing are no longer optional add-ons — they are the fastest, most direct way to reach your customers with offers, updates, reminders, and support that actually get seen.
At Growth NextGen, we build and manage end-to-end SMS and WhatsApp marketing programmes for D2C brands, ecommerce businesses, and B2B companies. From one-time broadcast campaigns to fully automated drip sequences, cart recovery flows, and AI-powered WhatsApp chatbots — we turn your customer list into a revenue engine that runs 24/7.
What We Deliver
From campaign strategy to automation setup — every message built to drive opens, clicks, and conversions.
Promotional and transactional SMS campaigns sent to segmented lists — with personalisation, A/B testing, and delivery tracking to maximise open and click-through rates.
Official WhatsApp Business API onboarding, number verification, message template approval, and platform integration — fully compliant and ready to scale.
AI-powered WhatsApp chatbots for lead qualification, order updates, FAQs, and customer support — automated flows that engage and convert without human intervention.
Automated cart abandonment recovery, post-purchase upsell sequences, and re-engagement drips via WhatsApp and SMS — triggered by customer behaviour in real time.
Sale announcements, flash offer alerts, festive campaigns, and loyalty programme messages — crafted for urgency and personalised by segment, location, or purchase history.
Delivery rate, open rate, click rate, reply rate, and conversion tracking — detailed reports after every campaign with optimisation recommendations for the next send.
Channel Comparison
Both channels are powerful — but they serve different purposes. Most high-performing brands use both together.
The most universally deliverable channel — works on every phone, no internet required, no app needed. Ideal for time-sensitive alerts and transactional messages.
Best for: OTPs, alerts, reminders, flash offers, order updates
Rich media, two-way conversations, and automation at scale — WhatsApp is where customers engage, ask questions, and complete purchases without leaving the chat.
Best for: D2C sales, cart recovery, lead nurturing, customer support
Our Process
A structured 6-step process from strategy to automation — built to drive results from day one.
We review your current messaging setup, customer list quality, opt-in flows, and past campaign data — then build a channel strategy aligned to your sales funnel and business goals.
We handle TRAI DLT registration, sender ID approval, template submissions, and WhatsApp Business API onboarding — so your account is fully compliant before the first message is sent.
We segment your customer database by behaviour, purchase history, location, and lifecycle stage — and set up opt-in flows to grow your list compliantly and continuously.
Our copywriters craft high-converting SMS copy and WhatsApp message templates — including promotional messages, drip sequences, chatbot scripts, and rich media content.
Cart abandonment flows, welcome sequences, post-purchase upsells, re-engagement campaigns, and chatbot decision trees — all built, tested, and activated in your chosen platform.
Post-campaign delivery, open, click, and conversion reports delivered after every send — with A/B test insights and recommendations that improve results with every campaign.

Case Studies
Real brands, real messages, real results.
D2C / Beauty
A D2C beauty brand had a 74% cart abandonment rate with no recovery system in place. We built a 3-step WhatsApp drip sequence — reminder at 1 hour, social proof message at 24 hours, and a discount nudge at 48 hours. The sequence recovered ₹18L in abandoned cart revenue within the first 60 days of going live.
Ecommerce / Fashion
A fashion ecommerce brand wanted to drive a flash sale without heavy ad spend. We built and sent a segmented WhatsApp broadcast to 85,000 opted-in customers — personalised by gender, past purchase category, and location. The campaign generated ₹32L in sales within 48 hours with a 5.2% click-to-purchase rate.
B2B / SaaS
A B2B SaaS company was losing inbound leads due to slow response times. We built a WhatsApp chatbot that captured enquiries, asked qualification questions, booked demo calls automatically, and escalated hot leads to sales reps instantly. Lead qualification volume tripled without any additional sales headcount.
D2C / Food & Beverage
An F&B brand wanted to increase repeat purchases from existing customers without discounting heavily. We ran a monthly SMS loyalty programme — personalised reorder reminders based on average purchase cycle, milestone reward messages, and exclusive subscriber-only offers. Repeat purchase rate jumped from 18% to 28% in 3 months.
Monthly retainer packages with defined campaign volumes and deliverables. Every package includes strategy, execution, and reporting. Start from $299.

FAQ
The regular WhatsApp Business app is limited to manual messaging and small contact lists — it cannot send bulk broadcasts, run automations, or integrate with your CRM. The official WhatsApp Business API is required for scale, automation, and compliance. We handle the entire API onboarding process for you.
Yes — provided you follow TRAI's DLT (Distributed Ledger Technology) regulations for SMS, and Meta's opt-in policies for WhatsApp. All our campaigns are fully compliant — we handle DLT registration, template approvals, and opt-in list management so you're never at risk of being flagged or blocked.
Transactional SMS (OTPs, order updates, alerts) can be sent 24/7 to any customer. Promotional SMS (offers, campaigns) can only be sent to opted-in customers within permitted hours. We manage both categories and ensure your messages are routed correctly to maximise deliverability and compliance.
A standard lead qualification or FAQ chatbot is typically live within 7–10 working days of API approval. More complex chatbots with CRM integrations, payment flows, or multi-step decision trees take 3–4 weeks. We'll give you a precise timeline after the strategy call.
Yes — we integrate WhatsApp and SMS with Shopify, WooCommerce, Laravel, Zoho CRM, HubSpot, and most custom platforms via API. This enables automatic triggers — cart abandonment messages, order confirmations, delivery updates — without any manual sending.
We set up opt-in touchpoints across your website (pop-ups, checkout flows), social media (Click-to-WhatsApp ads), and offline channels — ensuring every contact explicitly consents to receive messages. A high-quality opted-in list consistently outperforms large unverified lists on every metric.
