Automate personalized email campaigns with Google Docs, Sheets and SMTP

Emailing Using Google Sheet, Google Docs, and SMTP Automate personalized email campaigns using a Google Sheets contact list, a Google Docs template, and SMTP delivery. How It Works - Google Docs is used as the email template with variables: {{firstname}}, {{lastname}}, {{company}}, {{email}}. - Google Sheet contains your list of recipients (one per row). - For each contact, the workflow merges personal data into the Google Docs template. - Email is sent to each recipient via SMTP (batch size: 1). Use the Wait node to respect provider quotas. - After sending, the workflow updates the "process" column of the Google Sheet with the date/time. How to Use 1. Copy Templates: - Google Docs Template - Google Sheet Template - Find each document’s ID (the text after /d/ and before /edit in the URL). 2. Configure Workflow: - Enter your Google Docs and Google Sheets IDs in the settings node. - Set your email subject in the appropriate parameter. 3. Set Up Credentials: - Connect your Google account. - Configure the SMTP node with your mail server details. 4. Update Data: - Edit the Google Docs template with your message and variables. - Prepare your Google Sheet with these columns: email, firstname, lastname, company. 5. Deploy and Test: - Connect all nodes. - Test with a small contact batch. - Troubleshoot any node errors (indicated in red in n8n). Requirements - Google Credentials & permissions: For Sheets and Docs access. - SMTP Server: For email delivery (adjust Wait node for rate limits). - n8n Version: Tested on 1.105.2 (Ubuntu).

This workflow scans your email inbox for delivery errors (e.g., bounced messages), flags problematic email addresses in the Google Sheet and ensures future campaigns skip them.
