Welcome Series & Drip Builder

The problem this kills

You know a good welcome series would warm up new subscribers, but you never built one. The automation builder in your email platform felt like flying a plane - branches, delays, triggers, conditions - so the new-subscriber drip stayed on the someday list. Meanwhile every fresh signup gets your generic newsletter and nothing tailored, and you have no clean record of who got what, when.

The other quiet fear: sending the wrong thing to a real human. Automations run while you sleep. One typo, one stale offer, one person who already replied or bought but still gets the "haven't heard from you?" nudge - and you look careless.

This kills both problems. You design the sequence in plain language, a person approves the copy and the timing for every step before anything is allowed to send, and the tool enrolls people safely, sends on schedule, and keeps a complete record.

What you'll build

A small private web app, just for your team, that:

• Lets you design a sequence as a list of steps, each with a delay ("2 days after the last one"), a condition, and its own email copy.
• Can draft step copy with AI when you're stuck - but that draft is a draft until a human says yes.
• Makes a marketer approve the whole sequence (copy plus timing plus conditions) before it can be activated, and approve each step's copy before that step is ever allowed to send.
• Enrolls subscribers from live signup events or from a CSV of new signups, with a duplicate guard so the same person can't be enrolled in the same sequence twice.
• Sends each step on schedule through Resend, respecting exit conditions (stop if they reply, stop if they purchase) and putting an unsubscribe link in every email.
• Shows per-step engagement (sent, opened, clicked) and exports a send-log CSV.

What's inside the Implementation Plan

The plan is a runbook you paste into an AI coding agent (Claude Code). It builds the whole thing with you, step by step, and each step ends with a ready-to-copy prompt.

It opens by interviewing you about your business - your current signup flow, the platform you use, how your subscriber data is shaped and named, your typical and peak signup volumes, your timing and exit rules, and your messy edge cases. Then it reflects a short tailored spec back to you and waits for your thumbs-up. You get a welcome series built around how you actually work, not a generic template.

From there it walks through login, the database, the sequence designer, the approval gates, the enrollment and dedupe logic, the scheduled sender, engagement tracking, and the CSV export.

The governance it includes (this is the point)

• Login so only your team can open the tool.
• Row-level security so each organization only ever sees its own sequences, subscribers, and logs.
• A full audit trail - who designed, who approved, who activated, and exactly when.
• A hard human approval gate - the sequence can't activate and no AI-drafted step can send until a person reviews and approves it. The AI drafts; you commit.
• Duplicate guards - a subscriber-plus-sequence key means no one is enrolled twice and no step fires twice.

Who it's for

Email marketers and ops folks who never built a proper welcome series because the platform's automation builder felt intimidating. If you can describe your sequence in a few sentences and you want it to run safely without a developer, this is for you.

You've got this - paste the first prompt and let the agent interview you.
