Email subscription service with n8n forms, Airtable and AI

This n8n template shows how anyone can build a simple newsletter-like subscription service where users can enrol themselves to receive messages/content on a regular basis. It uses n8n forms for data capture, Airtable for database, AI for content generation and Gmail for email sending.

How it works

• An n8n form is setup up to allow users to subscribe with a desired topic and interval of which to recieve messages via n8n forms which is then added to the Airtable.
• A scheduled trigger is executed every morning and searches for subscribers to send messages for based on their desired intervals.
• Once found, Subscribers are sent to a subworkflow which performs the text content generation via an AI agent and also uses a vision model to generate an image.
• Both are attached to an email which is sent to the subscriber. This email also includes an unsubscribe link.
• The unsubscribe flow works similarly via n8n form interface which when submitted disables further scheduled emails to the user.

How to use

• Make a copy of sample Airtable here: https://airtable.com/appL3dptT6ZTSzY9v/shrLukHafy5bwDRfD
• Make sure the workflow is "activated" and the forms are available and reachable by your audience.

Requirements

• Airtable for Database
• OpenAI for LLM (but compatible with others)
• Gmail for Email (but can be replaced with others)

Customising this workflow

• This simple use can be extended to deliver any types of content such as your company newsletter, promotions, social media posts etc.
• Doesn't have to be limited to just email - try social messaging, Whatsapp, Telegram and others.
