Integration Overview & Prerequisites

Integrating WhatsApp with your CRM creates a unified customer communication platform that combines WhatsApp's 2.78 billion users with your existing sales and marketing workflows. This guide provides a platform-agnostic framework applicable to Salesforce, HubSpot, Zoho, Pipedrive, Microsoft Dynamics, and any CRM with API capabilities.

What You'll Achieve

  • Unified customer view: All WhatsApp conversations appear in CRM contact records
  • Automated workflows: Trigger WhatsApp messages based on CRM events (new lead, deal won, support ticket)
  • Bi-directional sync: Data flows both ways between WhatsApp and CRM automatically
  • Team collaboration: Multiple team members manage WhatsApp from within CRM interface
  • Analytics & reporting: Track WhatsApp metrics alongside CRM sales data

Prerequisites

Before You Start, Ensure You Have:

  • WhatsApp Business API access (not the free WhatsApp Business App)
  • CRM with API access (check your plan tier)
  • Admin permissions in both WhatsApp and CRM
  • Meta Business account verified and approved
  • Dedicated phone number for WhatsApp Business
  • Budget for BSP (Business Solution Provider) fees: $0.001-0.005 per message
  • Technical resource (or integration platform subscription)

⚠️ Common Misconception

The free WhatsApp Business App cannot integrate with CRMs. You must use the WhatsApp Business API, which requires approval from Meta and a Business Solution Provider (BSP) like Twilio, 360Dialog, Gupshup, or dedicated platforms like Wati, Respond.io, or Interakt.

Integration Architecture Patterns

There are three main architectural approaches for WhatsApp-CRM integration. Choose based on your technical resources, budget, and complexity needs.

Pattern 1: Direct API Integration (Custom Development)

┌─────────────────┐         ┌──────────────────┐         ┌─────────────────┐

└─────────────────┘         └──────────────────┘         └─────────────────┘

Best For

  • Non-technical teams without developer resources
  • SMBs and mid-market companies (1,000-50,000 messages/month)
  • Quick implementation needed (1-2 weeks setup)
  • Budget-conscious implementations ($29-299/month)

Limitations

  • Task/action limits on lower pricing tiers (100-1,000 tasks/month on Zapier Starter)
  • Limited customization compared to custom code
  • Can get expensive at scale ($299-599/month for high-volume)
  • Dependency on third-party platform reliability

Pattern 3: All-in-One Platform (Native Integration)

┌──────────────────────────────────────────────────────────────┐

│  Examples: Wati, Respond.io, Interakt, Yellow.ai             │
└──────────────────────────────────────────────────────────────┘

Best For

  • Teams without existing CRM or willing to switch
  • WhatsApp-first businesses (e-commerce, local businesses)
  • Fastest time to value (setup in days, not months)
  • Simplified billing (one platform, one price)

Trade-offs

  • CRM features less mature than Salesforce/HubSpot
  • Migration required if you already have CRM with years of data
  • Vendor lock-in concerns
  • May still need separate tools for email, social media, etc.

💡 Recommended Approach by Company Size

  • 1-10 employees: All-in-One Platform (Wati, Interakt) - $49-89/month
  • 11-100 employees: iPaaS Integration (Zapier + BSP) - $150-400/month
  • 100-500 employees: iPaaS or Direct API (depending on tech team)
  • 500+ employees: Direct API Integration for cost efficiency at scale

Pre-Integration Planning Checklist

Proper planning prevents 80% of integration failures. Invest 2-4 weeks in planning before any technical work begins.

Step 1: Define Business Objectives

1

Document Specific Goals

Don't just say "integrate WhatsApp." Define measurable outcomes:

  • Lead conversion: "Increase lead-to-opportunity conversion by 25%"
  • Response time: "Reduce first response time from 4 hours to 15 minutes"
  • Sales efficiency: "Enable sales team to manage 50% more leads without headcount increase"
  • Customer satisfaction: "Improve NPS from 42 to 60 via faster support"

Step 2: Map Customer Journey Touchpoints

Journey Stage WhatsApp Touchpoint CRM Action Needed
Awareness Click-to-WhatsApp ad → First message Create Lead record, source = WhatsApp Ad
Consideration Product inquiry, pricing questions Log conversation, update Lead Status, assign to sales rep
Decision Request quote, schedule demo Convert to Opportunity, create calendar event, send quote
Purchase Order confirmation, payment link Mark Deal as Won, create Order record, trigger fulfillment
Retention Support queries, reorder reminders Create Support Ticket, log in Service Cloud, send NPS survey

Step 3: Identify Data Flow Requirements

3

WhatsApp → CRM (Inbound Data)

What data should flow FROM WhatsApp INTO your CRM:

  • Contact information (phone number, name extracted from messages)
  • Conversation transcripts with timestamps
  • Customer intent signals (keywords like "pricing," "demo," "cancel")
  • Engagement metrics (response time, message frequency)
  • Opt-in/opt-out status for compliance
4

CRM → WhatsApp (Outbound Data)

What data should flow FROM CRM INTO WhatsApp messages:

  • Customer name for personalization
  • Deal/Opportunity details for context
  • Product recommendations based on CRM data
  • Appointment details from calendar
  • Account balance, invoice status, support ticket updates

Step 4: Define Automation Workflows

List the top 5-10 automations that will deliver the most value:

Trigger Condition WhatsApp Action
New Lead created in CRM Source = Website form Send WhatsApp welcome message within 5 minutes
Deal Stage = "Proposal Sent" No response in 48 hours Send follow-up message with case study link
Opportunity marked "Won" Deal value > $5,000 Send thank you + onboarding checklist
Support ticket created Priority = High Notify customer via WhatsApp, provide ticket # & ETA
Customer birthday (from CRM) Active customer last 6 months Send birthday greeting + 10% discount code
Invoice overdue > 7 days Amount > $500 Automated payment reminder with secure payment link

WhatsApp Business API Setup

The WhatsApp Business API is the technical foundation. You cannot integrate WhatsApp with a CRM using the free WhatsApp Business App.

Option 1: Direct Meta API Access (Enterprise)

1

Meta Business Verification

  • Create Meta Business Account at business.facebook.com
  • Complete Business Verification (requires business documents, 1-5 business days)
  • Add WhatsApp product to your Business Account
2

Apply for On-Premise API (Deprecated) or Cloud API

  • Cloud API (Recommended): Hosted by Meta, easier setup, free tier available
  • Register phone number, verify ownership via SMS code
  • Generate access tokens in Meta Business Manager
  • Configure webhooks for incoming messages

⚠️ Direct API Complexity

Direct Meta API access requires significant technical expertise: webhook servers, message queue management, template submission, quality rating monitoring. Most businesses use a BSP instead.

Option 2: Business Solution Provider (BSP) - Recommended

BSPs are Meta-approved partners that simplify API access and provide additional features:

BSP Provider Pricing Model Best For CRM Integration
Twilio $0.005/message + Meta fees Developers, custom integrations API-first, requires custom code
360Dialog €49/month + Meta fees European businesses, compliance focus Webhooks + API, technical setup
Gupshup $0.001/message (bulk discounts) High-volume senders (100k+ msgs/mo) API integration, good documentation
Wati $59/month (includes 1,000 msgs) SMBs, non-technical teams Pre-built integrations (Salesforce, HubSpot, Zoho)
Respond.io $99/month (includes 2,500 msgs) Mid-market, multi-channel Native CRM features + external integrations

💡 BSP Selection Criteria

  • Technical team available: Choose Twilio or 360Dialog for flexibility
  • No technical team: Choose Wati or Respond.io for UI-based setup
  • High volume (100k+ msgs/month): Gupshup for cost savings
  • Existing CRM investment: Match BSP to your CRM (e.g., Wati for HubSpot, Twilio for Salesforce)

Data Mapping & Field Synchronization

Data mapping determines how WhatsApp information translates into CRM fields. Poor mapping causes duplicate records, lost data, and workflow failures.

Essential Field Mappings

WhatsApp Data Point CRM Object CRM Field(s) Mapping Logic
Phone Number Contact/Lead Phone, Mobile Phone Primary unique identifier. Always include country code (+65, +1, etc.)
Contact Name (from WhatsApp profile) Contact/Lead First Name, Last Name Split on space if full name provided. Handle single-name cases.
First Message Timestamp Lead Lead Created Date, First Contact Date Use for lead source attribution and response time tracking
Conversation Transcript Activity/Task Comments, Description, Notes Each message = one Activity log with timestamp and direction (inbound/outbound)
Opt-in Status Contact WhatsApp Opt-in (custom field), Marketing Consent Boolean field. Critical for compliance. Update when user opts out.
Message Template ID Campaign/Activity Campaign Source, Email Template (repurposed) Track which template drove the conversation
Ad Click Source (CTWA ads) Lead Lead Source, Campaign Extract from WhatsApp API metadata. Critical for ROI tracking.

Handling Duplicate Records

Phone number is the primary unique identifier. Implement these de-duplication strategies:

1

Phone Number Normalization

Before checking for duplicates, normalize all phone numbers:

  • Remove spaces, dashes, parentheses: (123) 456-7890 → 1234567890
  • Always include country code: 1234567890 → +11234567890
  • Store in E.164 format: +[country code][number]
2

Duplicate Matching Logic

When a WhatsApp message arrives:

  1. Search CRM for existing Contact/Lead with matching phone number
  2. If found: Update existing record, log new activity
  3. If not found: Create new Lead record
  4. If multiple matches found: Use most recently updated record (or flag for manual review)
Example: Duplicate Check Pseudocode

normalized_phone = normalize_phone(whatsapp_number) existing_contacts = CRM.search(phone_field = normalized_phone) if existing_contacts.count == 0: # No match - create new Lead CRM.create_lead({ phone: normalized_phone, source: "WhatsApp", status: "New" }) elif existing_contacts.count == 1: # Single match - update existing contact = existing_contacts[0] CRM.log_activity(contact.id, whatsapp_message) else: # Multiple matches - flag for review CRM.create_task("Duplicate phone number detected: " + normalized_phone)

Custom Field Creation

You'll need to create custom fields in your CRM to capture WhatsApp-specific data:

Recommended Custom Fields

  • WhatsApp Opt-in Status (Boolean) - Marketing consent
  • Last WhatsApp Message Date (Date/Time) - Engagement tracking
  • WhatsApp Conversation Count (Number) - Measure engagement depth
  • First WhatsApp Message (Text) - Capture initial inquiry for context
  • WhatsApp Campaign Source (Picklist) - Track which ad/campaign drove contact
  • Preferred Communication Channel (Picklist: WhatsApp, Email, Phone) - Respect preferences
  • WhatsApp Business Account ID (Text) - If managing multiple WhatsApp accounts

Workflow Automation Design

Automation is where WhatsApp-CRM integration delivers exponential value. A well-designed workflow can handle thousands of conversations with zero manual intervention.

Anatomy of a WhatsApp-CRM Workflow

TRIGGER          CONDITION(S)           ACTION(S)
   │                  │                     │
   ▼                  ▼                     ▼
New Lead      Source = "WhatsApp"    1. Send welcome message (WhatsApp)
Created       AND                    2. Assign to sales rep (CRM)
              Lead Score > 70        3. Create follow-up task (CRM)
                                     4. Add to nurture campaign (CRM)

  • If 7-8 (Passive): "Thanks for your feedback. What could we improve?"
  • If 0-6 (Detractor): "We're sorry to hear that. Our manager [Name] will reach out to make this right." → Create escalation task

💡 Workflow Design Best Practices

  • Always personalize: Use CRM merge fields ([First Name], [Product], [Deal Value])
  • Time delays matter: Don't send messages at 2 AM. Use CRM time zone fields.
  • Respect opt-outs: Check opt-in status in every workflow condition
  • Provide opt-out: Include "Reply STOP to unsubscribe" in promotional messages
  • Track everything: Log every automated message as an Activity in CRM
  • A/B test messages: Use CRM reporting to compare message variations
  • Set workflow limits: Max 3 messages per day to avoid spam perception

Testing & Quality Assurance

Integration bugs can result in lost leads, duplicate records, or failed messages. Invest 2-3 weeks in thorough testing before going live.

Testing Checklist

Phase 1: Unit Testing (Individual Components)

  • Test webhook receives WhatsApp messages correctly
  • Verify phone number normalization logic (try +1, 001, no country code)
  • Confirm duplicate detection prevents double-creation
  • Test field mapping: Send test message, verify all fields populated in CRM
  • Check error handling: What happens if CRM API is down?

Phase 2: Integration Testing (End-to-End Flows)

  • New lead flow: Send WhatsApp message → Verify Lead created → Check auto-assignment → Confirm welcome message sent back
  • Existing contact flow: Message from known phone → Verify updates existing record (not duplicate) → Activity logged
  • Automation triggers: Manually trigger each workflow (create deal, update status, etc.) → Verify WhatsApp message sent within expected timeframe
  • Bi-directional sync: Update CRM field → Verify reflected in WhatsApp platform → Update WhatsApp conversation → Check CRM update

Phase 3: Load Testing

  • Send 100 WhatsApp messages simultaneously → Check webhook handling, queue management
  • Create 500 leads in CRM with auto-WhatsApp enabled → Verify all messages sent, no rate limiting errors
  • Monitor API rate limits (WhatsApp: 1,000 msgs/sec, CRM varies by platform)

Phase 4: Edge Case Testing

  • Phone number variations: +65 1234 5678, 6512345678, (65) 1234-5678
  • Special characters in names: O'Brien, José, 李明
  • Long messages (>1,600 characters): Verify message splitting or truncation
  • Media messages: Images, PDFs, videos → How are they stored in CRM?
  • Opt-out scenarios: User replies "STOP" → Verify opt-out logged, future messages suppressed
  • Multiple contacts, same phone: Household scenarios (how to handle?)

Common Test Failures & Fixes

Issue Root Cause Fix
Messages not creating CRM records Webhook not configured or failing silently Check webhook URL, verify SSL certificate, enable error logging
Duplicate leads created Phone number normalization inconsistent Implement E.164 format standardization before lookup
Automated messages not sending 24-hour customer service window expired Use approved message templates for messages outside 24hr window
CRM updates not triggering WhatsApp CRM workflow not configured or permission issues Check CRM automation logs, verify API credentials have write access
Messages sent to wrong contacts Field mapping error or query logic bug Add contact ID verification step before sending

Security & Compliance

WhatsApp-CRM integration involves customer data, requiring strict security and compliance measures.

Data Privacy & Compliance

1

GDPR Compliance (If serving EU customers)

  • Explicit consent: Before sending marketing messages, obtain clear opt-in ("By providing your WhatsApp number, you agree to receive promotional messages")
  • Right to access: Provide mechanism for customers to request all WhatsApp data stored in CRM
  • Right to deletion: Automate data deletion workflows when customer requests
  • Data minimization: Only sync necessary fields. Don't store message content if not needed.
  • Breach notification: Document data flows for GDPR breach notification requirements (72 hours)
2

WhatsApp Commerce Policy Compliance

  • No spam: Only message users who have opted in. First message must come from user.
  • Message templates: Promotional/marketing messages require pre-approved templates
  • Quality rating: Maintain "High" or "Medium" quality rating (low rating = reduced sending limits)
  • Prohibited content: No adult content, weapons, alcohol, tobacco, etc. (see WhatsApp Commerce Policy)
  • 24-hour window: After user messages you, you have 24 hours to send freeform messages. After that, use templates only.

⚠️ Quality Rating Penalties

If your WhatsApp account quality rating drops to "Low" due to user blocks/reports, Meta will:

  • Reduce messaging limits from 100k/day to 1k/day
  • Potentially suspend your account
  • Damage your business reputation

Prevention: Never buy phone lists. Always obtain explicit opt-in. Monitor block/report rates in Meta Business Manager.

Security Best Practices

API Security

  • Webhook verification: Verify WhatsApp webhook signatures to prevent spoofed messages
  • API token rotation: Rotate CRM and WhatsApp API tokens every 90 days
  • Least privilege access: Integration user should only have permissions needed (not admin)
  • IP whitelisting: Restrict CRM API access to BSP IP addresses only
  • HTTPS only: All webhooks must use SSL/TLS encryption
  • Rate limiting: Implement rate limits to prevent abuse (e.g., max 100 API calls/min)

Data Handling

  • Encryption at rest: Ensure CRM encrypts WhatsApp data (most enterprise CRMs do)
  • Encryption in transit: All API calls over HTTPS/TLS 1.2+
  • PII masking: In logs and error messages, mask phone numbers (e.g., +65****5678)
  • Access controls: Limit which CRM users can view WhatsApp conversations (role-based)
  • Audit logging: Log all WhatsApp data access for compliance audits

Compliance Documentation

Maintain these documents for regulatory compliance:

  • Data Processing Agreement (DPA): With your BSP and CRM vendor
  • Privacy Policy: Disclose WhatsApp data collection and usage
  • Opt-in Records: Timestamp and source of every WhatsApp opt-in
  • Data Flow Diagram: Map how WhatsApp data moves through systems
  • Incident Response Plan: Steps to take if breach or data leak occurs

Performance Optimization

Once live, continuously optimize for speed, cost efficiency, and deliverability.

Response Time Optimization

<5min
Target first response time
391%
Increase in conversion vs 30min response
15sec
Average user expects reply
  • Real-time webhooks: Use webhooks, not polling (polling = delayed responses)
  • Message queues: Implement queue (Redis, RabbitMQ) to handle spikes without webhook timeouts
  • Auto-assignment: Automatically assign leads to available reps within seconds
  • Chatbot first response: Use AI chatbot for instant acknowledgment while routing to human
  • Mobile notifications: Push notifications to sales reps' phones for urgent leads

Cost Optimization

WhatsApp messaging costs add up at scale. Typical costs:

Message Type Cost (varies by country) Optimization Strategy
User-initiated (within 24hr) Free Respond within 24hr window to avoid template costs
Marketing templates $0.0088 - $0.0155 (US) Segment audiences, only send to high-intent users
Utility templates (transactional) $0.0019 - $0.0042 (US) Use utility category for order confirmations, shipping updates
Authentication (OTP) $0.0020 - $0.0045 (US) Cheapest option for verification codes

💡 Cost-Saving Tips

  • Consolidate messages: Combine updates into one message vs multiple ("Your order #123 shipped via UPS, tracking: XYZ, ETA Friday")
  • Behavioral triggers only: Don't send to inactive users. Require action (cart add, form submit) before messaging.
  • Template approval strategy: Get utility templates approved (cheaper) instead of marketing where possible
  • Negotiate BSP rates: At 100k+ messages/month, negotiate volume discounts with your BSP

Deliverability Optimization

High deliverability = more messages reach customers = better ROI

  • Maintain quality rating: Aim for <1% block rate, <0.5% report rate
  • Verified business name: Complete Meta Business Verification for green checkmark (increases trust)
  • Clear sender identification: Use business name in first message ("Hi, this is [Company Name]...")
  • Avoid spam triggers: Don't use ALL CAPS, excessive emojis, link shorteners
  • Respect frequency: Limit to 1-2 messages per week for marketing (more for transactional)
  • Timing optimization: Send during business hours in customer's timezone (use CRM timezone field)

Troubleshooting Common Issues

Problem Diagnostic Steps Solution
Messages not appearing in CRM 1. Check webhook logs in BSP dashboard
2. Test webhook URL manually
3. Review CRM API error logs
• Verify webhook URL is accessible (not behind firewall)
• Check SSL certificate validity
• Confirm CRM API credentials haven't expired
• Review BSP webhook retry logic
CRM-triggered messages not sending 1. Check CRM workflow execution history
2. Review WhatsApp API error responses
3. Verify template status in Meta Manager
• Confirm phone number format is E.164 (+country code)
• Check opt-in status (can't message opted-out users)
• Verify template is APPROVED (not pending/rejected)
• Check 24-hour window hasn't expired for non-template msgs
Duplicate contacts being created 1. Compare phone number formats in duplicates
2. Check CRM duplicate detection rules
3. Review integration phone normalization logic
• Implement E.164 normalization before CRM lookup
• Update CRM duplicate rules to check phone field
• Use fuzzy matching for name+phone combination
• Run de-dupe job to merge existing duplicates
Slow response times (>5 min) 1. Check webhook processing time in logs
2. Review CRM API response times
3. Monitor queue/worker status
• Implement message queue (don't process synchronously)
• Add worker processes to handle volume
• Optimize CRM API calls (batch where possible)
• Use CRM async APIs instead of sync
• Consider upgrading CRM API tier (rate limits)
Messages failing with "Template not found" 1. Check Meta Business Manager template status
2. Verify template name in code matches exactly
3. Confirm language code is correct
• Template names are case-sensitive and must match exactly
• Re-submit template if rejected (check rejection reason)
• Language must match: en, en_US, es, etc.
• Wait for approval (can take 24-48 hours)
Quality rating dropped to "Low" 1. Check block/report rates in Meta Dashboard
2. Review recent message content
3. Analyze which templates have high block rates
• Immediately stop sending to purchased/scraped lists
• Pause all marketing campaigns until rating improves
• Only send to users who explicitly opted in recently
• Reduce message frequency
• Improve message relevance (segment better)
• Contact Meta support to appeal if wrongly flagged
Workflow triggers not firing 1. Manually test trigger conditions in CRM
2. Check workflow active status
3. Review field-level security permissions
• Verify field values exactly match conditions (case-sensitive)
• Ensure workflow is ACTIVE (not draft)
• Check integration user has read access to trigger fields
• Review CRM workflow order (other workflows might override)
• Check time-based triggers (scheduled jobs running?)
High API costs (unexpected bill) 1. Review message volume by template in Meta Dashboard
2. Check for workflow loops (infinite triggers)
3. Analyze message volume by campaign
• Identify and fix any workflow loops (A triggers B triggers A)
• Consolidate multiple messages into single message
• Segment campaigns to reduce volume
• Switch to utility templates (cheaper) where appropriate
• Implement daily send limits per contact

⚠️ Emergency: Integration Failure During High-Volume Period

Scenario: Black Friday sale, webhook stops working, thousands of messages queued

Emergency Response Plan:

  1. Immediate: Enable manual fallback (reps respond directly in WhatsApp platform, not CRM)
  2. Within 15 min: Post status update to team ("WhatsApp integration down, use direct platform access")
  3. Within 1 hour: Contact BSP support for webhook issue diagnosis
  4. Within 4 hours: Implement temporary fix (batch process to sync missed messages)
  5. Post-incident: Add monitoring alerts (webhook down > 5 min = page engineer)

Real-World Implementation Case Studies

Case Study 1: SaaS Company - HubSpot + Wati Integration

Company: B2B project management software (150 employees)
Challenge: Lead response time averaged 4 hours, 68% of leads went cold before first contact
Integration Approach: iPaaS (Zapier) connecting HubSpot to Wati

Implementation:

  • Week 1-2: Wati setup, WhatsApp Business API approval, template creation (4 templates approved)
  • Week 3: Zapier workflows built (new lead → WhatsApp within 3 min, deal stage → nurture sequence)
  • Week 4: Testing with 50 leads, refinement based on feedback
  • Week 5: Full rollout to all inbound leads

Technical Stack:

  • HubSpot Sales Hub Professional ($450/mo, 3 users)
  • Wati Growth Plan ($89/mo, includes 2,500 messages)
  • Zapier Professional ($299/mo for 10,000 tasks)
  • Total: $838/month
4hrs → 8min Avg first response time
+89% Lead-to-opportunity conversion
$127k Additional MRR in 6 months
15x ROI on integration cost

Key Learnings:

  • First message template critical: Tested 5 variations, personalized version (mentioning lead source) had 3.2x reply rate
  • Timing matters: Leads from webinar had 93% reply rate when messaged within 10 minutes vs 34% after 2 hours
  • Zapier task limit planning: Hit 10k limit in month 2, had to upgrade (forecast carefully)

Case Study 2: E-commerce Brand - Zoho CRM + 360Dialog Direct Integration

Company: Fashion e-commerce (Singapore, Malaysia, Indonesia markets)
Challenge: 73% cart abandonment rate, email recovery rate only 4.2%
Integration Approach: Direct API integration (custom Node.js middleware)

Implementation:

  • Month 1: 360Dialog setup (€49/mo), Zoho CRM custom fields, architecture design
  • Month 2-3: Development of middleware (Express.js server, MongoDB queue, worker processes)
  • Month 4: Testing, abandoned cart workflow, post-purchase upsell automation
  • Month 5: Gradual rollout: 10% → 50% → 100% of customers

Technical Stack:

  • Zoho CRM Professional ($23/user/month × 8 users = $184/mo)
  • 360Dialog (€49/month = ~$53/mo)
  • Meta API messaging costs (~$800/month for 120k messages)
  • AWS hosting (EC2 + RDS: $150/month)
  • Development cost: $28,000 (one-time, 3 months contractor)
  • Total ongoing: ~$1,187/month
4.2% → 18.7% Cart recovery rate
$89k/mo Recovered revenue from abandoned carts
27% Post-purchase upsell acceptance

Abandoned Cart Workflow That Worked:

  • 1 hour: "Hi [Name]! You left [Product] in your cart. Complete checkout in 1 click: [Link]" (12% conversion)
  • 24 hours: "[Name], still interested? Here's 10% off: [Code]" (22% conversion - highest!)
  • 72 hours: "Last call! Your 10% discount expires tonight." (8% conversion)
  • Combined recovery rate: 18.7% (vs 4.2% email)

Key Learnings:

  • WhatsApp open rate 98% vs email 22% (in their market)
  • Customers preferred WhatsApp for support (87% satisfaction vs 71% email)
  • Peak message volume during sales (11.11, Black Friday) required queue optimization
