A.R.C. Freshness Analysis

Tool Stack

1. Build your prospect list in Clay

   Use Clay to pull leads from LinkedIn, Apollo, or a CSV. Enrich each row with company size, recent news, tech stack, and job title. The goal is one unique signal per prospect that you can reference in the email opener.
2. Write personalized openers with Claude

   Export your enriched list and use Claude with a structured prompt to generate a unique first sentence for each prospect based on their recent activity or company news. Aim for openers that could only be written for that specific person. Process the full list in one Claude session — batch prompting via the API means hundreds of personalized openers in minutes.
3. Deploy the sequence via Resend

   Pipe Claude-written sequences into Resend via API for reliable, scalable delivery at pennies per email rather than a flat $40–100/mo subscription. Build a 3-step sequence: personalized opener day 1, value-add follow-up day 4, soft breakup day 10. Use Resend webhooks to track opens and clicks, then trigger follow-up sequences automatically via Make. The same infrastructure handles 100 or 10,000 emails without a tier upgrade.
4. Automate reply routing with Make

   Connect Resend to Make. When a prospect replies, automatically log them to Notion as a hot lead, remove them from the active sequence, and send yourself a Slack notification to respond within the hour. This loop runs 24/7 without any manual monitoring.
5. Track pipeline in Notion

   Maintain a simple Notion CRM with columns: Contacted, Replied, Meeting Booked, Closed. Use Notion AI to summarize reply threads and suggest next steps. Review your pipeline every Monday morning.
