Daily AI Email Campaigns with Groq + Gmail in n8n

Run a Daily AI-Generated Email Campaign from Groq to Gmail (in n8n)

This n8n workflow automatically generates and sends a daily marketing email using a Groq-hosted chat model—selecting the best campaign segment each day, formatting the result as strict JSON, and delivering the final campaign through Gmail.

What this workflow does

Built for reliable daily automation, the workflow follows this process:

• Daily schedule trigger: Runs at your chosen time and timezone.
• Loads your campaign configuration: Brand details, audience, products, segments, links, and recipient email addresses.
• Groq-powered n8n AI agent: Selects the best campaign segment for the day and generates one email as strict JSON containing: campaignType, subject, and body.
• Parses and validates output: Converts the AI response into clean fields; if parsing fails, it falls back to a generic subject/body.
• Sends via Gmail: Delivers the generated email to all configured recipients.

Use cases

• SaaS growth teams running daily lifecycle-style promotions without manually writing emails.
• n8n automation engineers needing a repeatable Groq + Gmail email pipeline with structured AI output.
• E-commerce or subscription brands rotating segments and discount codes daily while keeping content generation centralized.

Technical details

• Groq Chat (via n8n AI agent): Generates the campaign email as strict JSON.
• Schedule Trigger: Daily execution.
• Gmail node: Sends the final email using Gmail OAuth2 (send permissions required).
