Google Workspace Cold Email Management Script Needed

I’m looking for a developer to build a compliant cold email management script for Google Workspace. The tool should help manage legitimate B2B outreach campaigns while respecting Google Workspace limits and email compliance rules. Main features needed: Create and manage Google Workspace users using the official Google Admin SDK Import leads from CSV files Connect approved Google Workspace sender accounts Configure SMTP or Gmail API sending for each authorized account Set safe daily sending limits per sender Add delays between emails Schedule campaigns by day and time Personalize templates using variables like {{first_name}}, {{company}}, {{country}} Track sent emails, failed emails, replies, bounces, and unsubscribes Automatically stop sending to bounced or unsubscribed contacts Prevent duplicate contacts from being emailed twice Export sending reports Provide campaign logs Store credentials securely Include clear setup documentation Important requirements: The system must respect Google Workspace sending limits The system must not bypass Google limits or abuse account rotation Every campaign must include an unsubscribe option The tool must support bounce and complaint suppression The tool is for legitimate B2B outreach only Preferred technology: Python or Node.js Google Admin SDK Gmail API or SMTP integration SQLite / PostgreSQL / MySQL Simple dashboard or CLI Secure environment variable configuration Please apply only if you have experience with Google Workspace APIs, email deliverability, SMTP/Gmail API integration, and compliant cold email automation. I need a script that works like a lightweight cold email platform connected to Google Workspace. The script should allow me to: Create/manage Workspace users via Admin SDK Add approved sender accounts Upload leads by CSV Create personalized cold email campaigns Send emails with safe limits per account Distribute sending between authorized users without exceeding Google limits Track sent, failed, bounced, replied, and unsubscribed contacts Stop sending automatically to unsubscribed or bounced emails Export reports Provide full setup instructions This must be built for compliant B2B outreach, not for spam or bypassing Google restrictions
