Onboarding Email Sequence Writer

How the agent runs it

Client provides product walkthrough + ICP description. Agent maps activation milestones and writes 8–12 triggered email sequences (welcome, feature discovery, re-engagement, upsell) with subject lines and A/B variants.

Who this is for

This business is ideal for freelance writers, marketing consultants, or former SaaS marketing managers who already understand product-led growth and customer psychology. You need strong writing skills and familiarity with email marketing funnels, but no coding experience required—the AI and APIs handle the heavy lifting. If you've written copy for B2B products or managed customer onboarding, you can start immediately and command premium rates.

Market opportunity

SaaS onboarding is a $2B+ market problem: 90% of new users churn within the first week due to poor activation sequences. Companies are increasingly willing to pay $500–$2.5K per project as conversion rates directly impact lifetime value. The shift toward behavior-triggered, personalized email (vs. batch-and-blast) has accelerated post-2023, making specialized sequence writing a high-demand skill that most agencies still outsource.

Tech stack

Monetization

$500–2.5K per sequence package. Retainer for ongoing A/B optimization.

Key risks

• → Requires access to product analytics for behavior triggers
• → Personalization depth limited without CRM integration

Getting started

1. 1
   Set up Claude API + Customer.io account

   Register for Claude API (Anthropic) and create a free Customer.io sandbox environment to understand how behavior-triggered emails work. This takes 30 minutes and gives you hands-on familiarity with the tools your clients will use to deploy your sequences.
2. 2
   Build a portfolio with 2–3 demo sequences

   Pick 2–3 real SaaS products (Slack, Notion, Calendly) and reverse-engineer their onboarding flows, then write a 6–8 email sequence for each. Post these on your website or LinkedIn as proof of concept; prospects want to see your writing style before hiring.
3. 3
   Create a simple intake questionnaire template

   Design a one-page form that captures product demo links, ICP details, activation metrics, and tone preferences from clients. This streamlines the discovery phase and ensures you extract the right information to write effective sequences on the first pass.
4. 4
   Develop your prompt framework for Claude

   Write a detailed system prompt that instructs Claude to map activation milestones, generate subject lines, and produce A/B variants. Test it with your portfolio projects to refine outputs and save time—this becomes your competitive edge and ensures consistent quality at scale.
5. 5
   Launch outreach to SaaS founders + marketers

   Identify 50 B2B SaaS companies in underserved niches (fintech, HR tech, analytics) via ProductHunt or Crunchbase and pitch your service directly to CMOs or Growth leads. Emphasize your ability to deliver 8–12 sequences in one week at a fraction of agency costs.
