"content": "# Automated Email Follow-Up Workflow\n\nThis n8n template demonstrates how to automate personalized cold email follow-ups using AI personalization and database tracking. Perfect for sales teams, recruiters, and agencies managing high-volume outreach.\n\n**Use cases:** Follow up with cold leads, re-engage trial users, nurture conference contacts, recruit candidates, or follow up with proposal recipients.\n\n\n\n## How it works\n\n* NocoDB fetches all leads and filters those needing follow-up today based on the \"Next Follow up/Contact\" date\n* A switch node routes leads to the appropriate follow-up stage (1-4) based on which follow-ups have already been sent\n* AI personalizes each email template by inserting the recipient's name while keeping the rest of the content intact\n* Emails are sent via SMTP (or Gmail node), then the database updates to mark the follow-up as sent and schedule the next one\n* The workflow runs daily at 10 AM to automatically process follow-ups without manual intervention\n\n\n\n## Good to know\n\n* Each AI personalization costs ~$0.001 with Groq (free tier available). See Groq pricing for details.\n* Follow-up schedule: Day 3, 7, 12, 16 after initial contact (fully customizable)\n* Leads marked \"Not Interested\" are automatically excluded from future follow-ups\n* The workflow only processes leads with an \"Initial Contact Date\" set - this triggers the entire sequence (The initial Contact is done manually and updated manually)\n\n\n\n## How to use\n\n* The schedule trigger runs daily but can be replaced with manual trigger or webhook for immediate testing\n* Customize the 4 email templates in the AI nodes to match your brand voice and offering\n* Adjust follow-up intervals by modifying the \"Update a row\" nodes (currently +4 or +5 days between follow-ups)\n* Import your lead list to NocoDB with minimum required fields: first_name, last_name, email, Initial Contact Date\n\n\n\n## Requirements\n\n* **NocoDB account** - Free lead database (You can use any database-Google Sheets, Airtable etc. However ensure the essential details below are in the database)\n* **Groq API key** (or OpenAI/Ollama) - For AI personalization (Swap this for any LLM you like/have)\n* **SWITCH** the 'Send Email' nodes for the **Gmail** Node and set it up using OAuth\n\n## Database Structure\n\n**Critical columns** (workflow will fail without these):\n* `first_name` - Recipient's first name for personalization\n* `email` - Where to send follow-ups\n* `Initial Contact Date` - Triggers the sequence when set\n* `Next Follow up/Contact` - Determines when next follow-up sends\n* `Follow Up 1 (Day 3) Y/N` - Tracks completion (null/Y)\n* `Follow Up 2 (Day 7) Y/N` - Tracks completion (null/Y)\n* `Follow Up 3 (Day 12) Y/N` - Tracks completion (null/Y)\n* `Follow Up 4 (Day 16) Y/N` - Tracks completion (null/Y)\n* `Not Interested` - Excludes leads from sequence\n\n**Optional enrichment columns:**\norganization_name, title, industry, linkedin_url, city, organization_website_url, organization_annual_revenue_printed, organization_linkedin_url, organization_phone, organization_country\n\n"

Create NocoDB/datbase table with required columns: first_name, last_name, email, Initial Contact Date, Next Follow up/Contact, Follow Up 1-4 Y/N, Not Interested\n2. Import your lead list or add leads manually\n3. Set \"Initial Contact Date\" to when you first contacted them\n4. Calculate \"Next Follow up/Contact\" as Initial Contact Date + 3 days\n\n**Workflow Configuration (10 minutes):**\n1. Add NocoDB/dtabase credentials (get API token from NocoDB settings)\n2. Add Groq/LLM credentials (free at console.groq.com)\n3. Add email credentials (SMTP details or Gmail OAuth)\n4. Update email templates in the 4 AI personalization nodes\n\n**Testing (5 minutes):**\n1. Add test lead with your email and today's follow-up date\n2. Execute workflow manually\n3. Verify email received and database updated\n4. Test each follow-up stage by updating the test lead\n\n**Go Live:**\n1. Set schedule trigger to your preferred time (default: 10 AM daily)\n2. Activate workflow\n3. Monitor for first few days to ensure proper execution\n"
