Automate Personalized Email Campaigns with Google Docs, Sheets and SMTP

Description

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.

Set Up Credentials:

Update Data:

After running your email campaign, some messages may fail to deliver. 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.
