WhatsApp Marketing Services
WhatsApp has a 98 percent open rate. Email averages 20 percent. SMS averages 30 percent. No other marketing channel reaches customers with the same read rate, and in India and most of Southeast Asia and the Middle East, WhatsApp is where customers actually want to hear from the brands they buy from. Oddtusk builds WhatsApp marketing programmes on the Business API that automate the full customer lifecycle: from order confirmations and cart recovery to reactivation campaigns and post-purchase reviews, turning your customer list into a revenue channel that compounds with every message sent.

WhatsApp is not a broadcast channel. It is a conversation channel.
Most brands that try WhatsApp marketing send the same promotional blast to their entire list and wonder why opt-out rates are high. WhatsApp customers are hypersensitive to irrelevance. A message that does not feel personalised to their situation gets blocked immediately and permanently. Oddtusk builds WhatsApp programmes around segmented customer lists, triggered automation that fires based on behaviour, and message templates that feel personal rather than promotional. WhatsApp works best when integrated with your CRM and paired with remarketing campaigns across Meta and Google.
WhatsApp Business API Setup
We handle the full Business API onboarding process: Meta Business Manager verification, phone number registration, display name approval, and BSP or direct API integration with your ecommerce platform. Shopify Flow, WooCommerce, and custom API connections are configured to trigger WhatsApp messages automatically from order events, customer actions, and CRM data without manual send operations from your team.
Abandoned Cart and Checkout Recovery
WhatsApp cart recovery outperforms email recovery for Indian ecommerce brands because WhatsApp is read within minutes of receipt. We build three-message recovery sequences triggered by cart abandonment events: an immediate reminder at 30 minutes, a social proof message at 3 hours, and an offer-based incentive at 24 hours for audiences that have not converted. Each message is personalised with the specific product left in cart. This is coordinated with paid remarketing flows for maximum funnel coverage.
Transactional and Order Flow Automation
Order confirmation, payment confirmation, dispatch notification, out-for-delivery alert, and delivery confirmation messages are all configured as automated flows triggered by your OMS or Shopify order events. Transactional messages have the highest open and engagement rates of any WhatsApp message type and establish the channel as a trusted communication medium before any promotional messaging begins.
Broadcast Campaign Strategy
Promotional broadcast campaigns require precise list segmentation to maintain low opt-out rates. We segment customer lists by purchase history, product category affinity, and purchase recency before building campaigns, ensuring every broadcast goes to the customers most likely to find it relevant. Message frequency is managed to prevent fatigue: customers who receive too many irrelevant messages block the number permanently. This segmentation logic is built on top of your CRM integration.
Post-Purchase Lifecycle Flows
The post-purchase window is the highest-value moment to build loyalty. We build automated sequences that request reviews 5 to 7 days after delivery, introduce complementary products at day 14, send replenishment reminders for consumables at the expected reorder window, and offer loyalty programme enrolment at day 30. Each touch is triggered by timing and purchase data, not manual curation. This is the WhatsApp layer of our retention marketing programme.
Template Approval and Compliance
WhatsApp Business API messages require pre-approved message templates for all outbound communication. We write, structure, and submit templates for Meta approval, managing the approval process across all required template categories: utility, marketing, and authentication. Templates are written to pass Meta's approval requirements while retaining the personalisation and brand tone that make them effective. This process is part of our broader workflow automation build.
35% cart recovery rate. 5x revenue per message vs email. 25%
WhatsApp cart recovery drives 30 to 40 percent recovery, higher than email. Messages are read instantly, capturing intent before it drops. Works alongside paid remarketing for multi-channel funnel recovery.
Segmented WhatsApp broadcasts drive 5 times more revenue per message than email. Higher opens and CTRs turn the same list into more revenue. All tracked through GA4 attribution.
Post-purchase flows: reviews, cross-sell, and replenishment reminders boost repeat purchases by 20 to 30 percent in 90 days. Timely, relevant messages bring customers back, compounding retention marketing outcomes.

Straight answers to the questions that matter.
The WhatsApp Business App is a standalone mobile application for small businesses managing a small volume of customer conversations manually. The WhatsApp Business API is a programmatic interface that allows businesses to send automated messages at scale, integrate with CRM and ecommerce platforms, and manage customer communications through BSP software. The API is required for automation flows, broadcast campaigns, and any volume of messaging beyond what a single person can manage manually on a mobile device.
Yes. WhatsApp Business API policies require explicit opt-in consent from customers before you can send them marketing or promotional messages. Transactional messages such as order confirmations and delivery updates are permitted without separate opt-in where the customer has provided their number for that purpose, but marketing and broadcast communications require a clear consent capture at checkout, on website forms, or through a dedicated opt-in flow. We set up compliant opt-in mechanisms as part of the onboarding process. This also supports email marketing list building when done at the same touchpoint.
A WhatsApp message template is a pre-approved message format that businesses must use for all outbound communications initiated by the business rather than by the customer. Meta reviews every template before it can be sent to ensure it complies with their messaging policies, contains accurate content, does not include prohibited content categories, and falls within the correct template category: utility, authentication, or marketing. Templates must be approved before any campaign or automation flow using them can go live.
For Indian ecommerce brands, WhatsApp cart recovery consistently outperforms email cart recovery on both open rate and conversion rate. WhatsApp messages are opened by 80 to 90 percent of recipients within 30 minutes of receipt. Email cart recovery averages 40 to 60 percent open rate with a much longer time to open. The immediacy of WhatsApp delivery means recovery messages reach customers while the product is still top of mind. Combine this with paid remarketing flows for the highest possible funnel recovery rate.
BSP selection depends on your monthly message volume, platform integration requirements, and budget. For Indian D2C ecommerce brands on Shopify, Wati and Interakt are the most commonly used BSPs with native Shopify integrations. Gupshup and 360dialog suit higher-volume senders with custom API integration requirements. For brands already using a CRM like Salesforce or HubSpot, BSPs with prebuilt CRM connectors reduce integration complexity. We recommend a BSP based on your specific technical environment rather than defaulting to a single platform.
Opt-out rate is the most important health metric for WhatsApp marketing. We manage it through three levers: list segmentation ensures every broadcast goes to customers who have shown category affinity for the promoted product, message frequency limits prevent the channel from becoming over-messaged, and message relevance is maintained by personalising every broadcast with customer-specific data. An opt-out rate above 1 percent on any campaign triggers an immediate review of the targeting and message content. This segmentation is built on consumer behaviour analysis from your CRM and order history.
Yes. WhatsApp is the dominant messaging platform in India, Southeast Asia, the Middle East, Africa, and Latin America. In Europe, WhatsApp penetration is also high though GDPR consent requirements add additional compliance complexity to the opt-in process. For brands operating in multiple markets, WhatsApp marketing strategy is adapted per market based on penetration rates and local regulatory requirements. We do not recommend WhatsApp as a primary CRM channel for North American or Australian audiences where SMS and email marketing remain dominant.
Shopify integration is achieved through a combination of BSP app installation and webhook configuration. Most major BSPs including Wati, Interakt, and Gupshup have direct Shopify apps that pull order data, customer data, and checkout events. For more complex automation requirements, Shopify Flow is used to trigger custom webhook events that pass structured data to the BSP API. The integration covers order events, abandoned checkout events, customer creation events, and product data for personalised cart recovery messages. This setup also feeds clean event data into GA4 for attribution via GTM.
The WhatsApp Green Tick is a verification badge displayed next to the business name in conversations, indicating Meta has verified the business as a legitimate and notable brand. It is not required to send messages or run automation: businesses can operate the full WhatsApp Business API without it. The Green Tick is valuable for building customer trust and reducing message recipient concern about message legitimacy. Meta has specific eligibility criteria for the Green Tick that include notable brand presence and compliance history. It works alongside your broader marketing automation infrastructure.
Monthly reports cover delivery rate, read rate, CTR, and conversion rate by flow and broadcast campaign, revenue attributed to WhatsApp-driven sessions in GA4, abandoned cart recovery rate, opt-out rate by campaign, and repeat purchase rate from post-purchase flow recipients versus non-recipients. WhatsApp revenue attribution uses UTM parameters on all CTA links to track sessions and conversions in GA4, supplemented by order-level analysis in Shopify to confirm WhatsApp-attributed purchases align with platform-reported figures.
