Flow

The simplified flow (9 active nodes):

Receive Brief → Set Config → Fetch SERP Data → Build Claude Prompt
→ Call Claude AI → Parse Claude Response → Save to Google Sheets
                                         → Send Delivery Email
                                         → Send Response

After importing, replace these 5 values in the Set Config node:

Field	Replace with
`YOUR_ANTHROPIC_API_KEY`	Your Anthropic key
`YOUR_SERPER_API_KEY`	Your Serper.dev key (free tier works)
`YOUR_SENDGRID_API_KEY`	Your SendGrid key
`YOUR_GOOGLE_SHEET_ID`	Your Sheet ID from the URL
`YOUR_GSHEETS_CREDENTIAL_ID`	Set up Google Sheets OAuth in n8n credentials

The workflow handles all 4 content types (blog_post, ad_copy, email_sequence, social_captions) through a single Claude call with type-specific prompts — no branching needed.
