What This Workflow Does

This automation solves the tedious process of manually sending personalized emails to contacts stored in Google Sheets. It eliminates repetitive work while ensuring consistent, error-free communication.

The workflow intelligently processes your contact list, filters recipients based on your criteria, prevents duplicate sends, adds delays between emails to respect provider limits, and updates your spreadsheet automatically - all while using your existing SMTP email service.

How It Works

1. Fetch contacts from Google Sheets

Connects to your Google Sheet and retrieves contact data including email addresses and any personalization fields.

2. Filter recipients

Applies your rules to determine who should receive emails (like no-show attendees or specific lead statuses).

3. Check for duplicates

Verifies each contact hasn't already received an email by checking a 'sent' column.

4. Send personalized emails

Uses your SMTP credentials to send customized messages with merge fields from your spreadsheet.

5. Add delays between sends

Respects email provider limits by spacing out messages to avoid triggering spam filters.

6. Update records

Marks contacts as sent in your Google Sheet automatically after each successful delivery.
