💰$30–75/mo — Lemlist replaced with Resend. Estimated saving: $40–100/mo at scale vs flat Lemlist subscription.

⚡Resend sends via API at pennies per email rather than a flat rate. Clay enriches, Claude personalises, Make orchestrates, Resend delivers — the A.R.C. redesign the feedback described.

Step-by-step guide

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.

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.

Heat score:85Rising

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.

Heat score:59Rising

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.

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.
