Wiring HubSpot + WhatsApp + Email in one afternoon

The standard mistake: pick a CRM, pick an email tool, pick a WhatsApp tool, then try to make them talk. By the time you’re done you’ve got 4 hours of integration debugging per workflow.

The right way: pick tools that already talk, design the schema first, then build.

The stack

• HubSpot Free — CRM + forms + automation
• MailerLite (or HubSpot Marketing) — transactional + nurture emails
• WhatsApp Business API via 360dialog — outbound messaging
• Zapier or n8n — glue for edge cases

Step 1: Schema first (30 min)

Before you touch any tool, write the contact schema. This is the source of truth.

• email (primary key)
• first_name, last_name
• phone (E.164 format: +971501234567)
• whatsapp_opt_in (boolean)
• lead_source (website, ad, referral, organic)
• lead_stage (new, contacted, qualified, customer, churned)
• last_touch (datetime)
• tags (multi-select)

Step 2: Form → CRM (45 min)

Build your contact form. Map every field to a HubSpot property. Test by submitting — the contact should appear in HubSpot within 30 seconds.

Step 3: Welcome email (1 hour)

3-email welcome series:

1. Immediate — “Welcome to [Brand]”
2. Day 2 — 3 quick tips
3. Day 5 — 1-question survey

Step 4: WhatsApp notification (45 min)

Two flows:

• New lead → notify you: “🚨 New lead: {{name}} ({{email}})”
• Booking confirmation → notify them: “Hi {{name}}, your call is confirmed for {{date}}”

The 360dialog setup takes longest because WhatsApp wants template pre-approval (24-48 hours).

Step 5: Lead scoring (1 hour)

• +10: opens an email
• +20: clicks a link
• +30: views pricing page
• +50: books a call
• +100: pays an invoice
• -10: unsubscribes

When score hits 50+, fire a WhatsApp + Slack notification.

Step 6: Test (1 hour)

Use your own email. Submit. Check every link. Confirm WhatsApp ping arrives.

Total: ~5 hours

An afternoon. You now have an automation stack 80% of “launched” startups don’t have after 6 months.
