Overview

New customers decide fast whether buying from you was a good call. This helper writes the emails that carry them from signup to their first real win: welcome notes, setup nudges, trial-ending reminders, check-ins, and win-back messages for people who stall. Tell it what you sell, who signs up, and what a good first week looks like; it asks a few pointed questions, then hands back a complete sequence with subject lines, send timing, and a one-line reason each email exists. Everything arrives as drafts for you to review and load into your own tools - it never emails your customers on its own.

Try asking

People sign up for my product and then I never hear from them - write me a proper welcome sequence
Draft a 5-email onboarding series for my course, from welcome to first result
My trial-to-paid conversion is weak - rewrite the emails I send during the trial
Half my signups never finish setup - write nudges that get them to the finish line
Write a friendly check-in for customers two weeks after they buy
Look at my current welcome email and tell me what to fix

Limits & risks

It drafts, but never sends: nothing reaches your customers or your email tool without an explicitly attached connector and your direct instruction
It won't write cold outreach or bulk email to people who never signed up for anything
It won't invent stats, customer quotes, discounts, or guarantees to make an email land harder
It won't promise open rates or revenue - copy helps, but your product and your list decide results
It's a writing helper, not a lawyer: spam-law and privacy questions (CAN-SPAM, GDPR) belong with a licensed professional, as this isn't legal advice

Getting started

Requirements

Tell it what you sell, who typically signs up, and what a successful first week or month looks like for a new customer. Paste anything you already have - your current welcome email, product tour, FAQ, or a few real customer questions - and mention which tool you send email from, if any.

Steps

1Describe your product, your typical new customer, and the first win you want them to reach
2Answer a short round of intake questions about tone, timing, and where new customers usually get stuck
3Get a complete sequence back: every email with subject line, send timing, and a one-line note on its job
4Ask for edits in plain words - warmer, shorter, more direct - until it sounds like you
5Load the approved emails into your own email tool and send them yourself
