EMAIL & CUSTOMER OPERATIONS
Email lifecycle automation
A connected system for subscriber management, campaign creation, scheduled follow-ups and reporting.
THE BUSINESS CHALLENGE
Less manual work.
More connected systems.
When signup forms, subscriber lists and follow-ups live in separate places, running a campaign becomes a series of manual handoffs.
Five n8n workflows bring the lifecycle together around a shared Google Sheets data model, with Gmail delivery and an optional Claude drafting route.

Build status
Five implementation exports were reviewed. Provider credentials, sender setup and end-to-end delivery still require configuration and testing. These maps show the implemented workflow structure; they do not represent a verified live campaign.
