Daily AI Email Campaigns in n8n: Groq + Gmail Send Workflow

Automatically generate and send a daily AI marketing email from n8n (Groq + Gmail)

This n8n workflow runs every day at 9am, uses Groq to generate a tailored marketing email in the right format, and then sends it via Gmail to your configured recipients—fully automated.

What this workflow does

• Scheduled delivery: A schedule trigger starts the workflow daily at 9am (cron and timezone configurable).
• Loads campaign inputs: It reads brand details, audience/segments, key dates, links, and recipient email addresses from your campaign parameters.
• Chooses the best segment + writes the email: Using a LangChain AI agent with the Groq chat model, it selects the most relevant campaign segment for today and generates a JSON email subject and body.
• Parses and validates AI output: The workflow parses the AI response into structured fields (campaign type, subject, body, and recipients). If parsing fails, it falls back to safe defaults.
• Sends via Gmail: It delivers the generated campaign as a plain-text email through the gmail node to the recipients you provide.

Use cases

• SaaS teams sending daily personalized marketing updates based on key dates and audience segments.
• Automation engineers building a reliable AI email campaign workflow in n8n with structured outputs and validation.
• Ops teams that want consistent, scheduled AI-driven messaging without manual copy-paste.

Technical details

• Nodes/stack: schedule trigger, set, code, gmail, sticky note, and n8nn8n-nodes-langchainagent.
• AI: Groq chat model via the LangChain agent to generate the email as structured JSON.
• Gmail: Uses Gmail OAuth2 credentials; ensure the connected account can send emails.

Set your Groq and Gmail credentials, update your campaign parameters, and let your daily AI email campaigns run automatically in n8n.
