I need an AI Pro to craft a 3-email onboarding sequence for TaskFlow, a SaaS platform. The sequence should help new users get started smoothly.Email 1: Welcome and quick-start guide — greet the user, set expectations, and give 1–2 simple first actions.Email 2: Top 3 features walkthrough — highlight 3 key benefits/features and show how each helps the user achieve a quick win. (If specific features aren't provided, use sensible placeholders like 'Task Templates', 'Collaboration', 'Reporting'.)Email 3: Live demo invite — encourage the user to book a 1-on-1 demo or join a live session to see advanced capabilities, with a clear call to action.Each email must be 200 words max (including subject line). Subject lines should be catchy and benefit-driven. Tone should be warm, professional, and SaaS-appropriate. Please deliver the sequence as a single document with clear labeling. Budget is $100.
