ListShield - Prevent fast email list churn

Help small business owners send highly relevant content right after signup to reduce unsubscribes

Problem

A SaaS founder noticed that if emails after signup feel too promotional or generic, subscribers unsubscribe quickly. Many small business owners treat signups as a win but neglect post-signup retention, leading to rapid list churn.

Solution

A lightweight email sequence optimization tool. It connects to your email list (e.g., Mailchimp), monitors new subscribers' opens and clicks, and flags low-engagement users. You can set simple rules, like sending a content email related to the signup source within 3 days instead of a generic promo. It also provides unsubscribe reason survey templates.

Users

Small business owners, indie creators, and SaaS founders using email marketing—especially those with lists under 1,000 and limited ops experience.

MVP

Connect one email platform; monitor first 7 days of opens/clicks; provide 3 preset high-relevance email templates; auto-send survey to collect unsubscribe reasons; simple dashboard.

Revenue

Monthly subscription tiered by list size.

Why now

Indie creators and small businesses increasingly rely on email lists but lack retention tools; indie developers can build fast with simple email APIs and a rules engine.
