Zapier Twilio Lead Notification Automation

I need a simple yet reliable workflow that links a Google Sheet with Zapier and Twilio so every time a new lead is entered—or when a follow-up date I specify arrives—the prospect automatically receives an SMS and an email.

The Google Sheet is already structured with columns for name, phone, email, creation date. What I’m missing is the automation layer:

• When a new row appears, Zapier should instantly push one Twilio SMS and one email (Gmail or Zapier Email) using the templates I’ll provide.
• On the morning of each scheduled follow-up date, the same lead gets a gentle reminder through both channels.

This is a comprehensive **Project Specification Document** designed to be copied directly into a Google Doc for your technical lead. It outlines the architecture for a CRM-free, automated lead follow-up system centered on **Google Sheets** and **Zapier**.

## 4. Automation Workflows (The Zaps)

### Zap 1: Initial Intake & "Day 0" Outreach

*
**Trigger:** New Spreadsheet Row in Google Sheets.


*
**Action 1:** Format phone number to E.164 (if necessary).


*
**Action 2:** Send "Initial Invitation" Email (Gmail) with booking link.


*
**Action 3:** Send "Initial Invitation" SMS (Twilio) with booking link.


*
**Action 4:** Update Row: Set `Status` to "Pending" and `Follow-up Count` to 1.



### Zap 2: The Persistence Engine (Timed Sequence)

* **Trigger:** New Lead added to the Google Sheet.
* **Sequence Step (Day 1):**
1.
**Delay:** Wait 24 hours.


2.
**Filter:** Only continue if `Status` = "Pending".


3.
**Action:** Send Follow-up #1 (Email/SMS).


4.
**Action:** Update Row: Increment `Follow-up Count` and set `Last Follow-up`.




*
**Sequence Step (Day 3):** Repeat logic above with 48-hour delay.


*
**Sequence Step (Day 7):** Repeat logic above with 4-day delay.



### Zap 3: The "Kill-Switch" (Booking Detection)

*
**Trigger:** New Event Created in Shared Google Calendar.


*
**Action 1:** Find Row in Google Sheets by matching the attendee's Email.


*
**Action 2:** Update Row: Set `Status` to "Booked".


*
**Effect:** This stops Zap 2 from proceeding past its next "Filter" step, halting all outreach.

## 5. Compliance & Communication Standards

*
**CASL (Canada):** All emails must contain an unsubscribe link and physical office address.


*
**SMS Requirements:** Every text must include "Reply STOP to opt out".


*
**Template Personalization:** Use `[First Name]` in all messaging to maintain a high-touch feel.



---

## 6. Testing Requirements

1.
**Manual Lead Entry:** Add a test row; verify SMS/Email arrive within 5 minutes.


2.
**Booking Test:** Schedule an appointment on the calendar; verify Sheet status changes to "Booked".


3.
**Filter Verification:** Ensure no follow-ups trigger once status is "Booked" or "Opted Out".
