How to Win Your First Client

  1. Pick one niche such as recruiting agencies or SaaS founders.
  2. Create a sample sheet with 20 personalized first lines.
  3. Send a short pitch offering a free sample batch.
  4. Use results and reply-rate improvements to upsell retainers.
Focus on a Clear Metric

Founders care about replies and meetings booked. Frame your service as a performance upgrade, not a writing service.

Why This Business Works

Outbound teams have recurring needs and clear ROI. Once your personalization improves campaign performance, clients have a strong reason to keep paying monthly.
