The First 10
- Who

- Where to find them
- Your Shopify customer list, sorted by last order date, filtered to people who agreed to marketing email.
The first message
Hi {first name}, it has been a while since your last order of {product}, so I wanted to say thank you for being a customer. We have {new thing or restock} now, and if anything about your last order was not right, just reply and tell me. {your name}, {store}
- Then
- Let Churn Win-Back Loop draft the next round for the wider lapsed list, and Feedback Theme Tally group every reply by reason.
- Email only customers who agreed to marketing email, with an unsubscribe link.
- No discounts promised by the bot. You set any offer.
Costs and Break-Even
Setup
- VRun It With Us setup: $1,500 founding price for the first 3 setups (normally $2,500), one time for one bot setup, starting with a $300 deposit that counts toward it. Source, checked 30 Oct 2026.
Monthly tool bill
- VGrok Bot Premium: $30 a month (runs every Grok bot in this stack). Source, checked 27 Oct 2026.
- VShopify Basic: $39 a month paid monthly ($29 paid yearly), plus card fees from 2.9% + 30 cents. Source, checked 29 Oct 2026.
- Vn8n: Community Edition $0 licence if you self-host; Cloud Starter 20 euros a month billed annually. Source, checked 27 Oct 2026.
- VOpenAI API (gpt-4.1-mini): $0.40 per 1M input tokens and $1.60 per 1M output tokens. Source, checked 27 Oct 2026.
- EExample bill: Grok Bot Premium $30 + Mailchimp Free $0 (under 250 contacts) + Slack Free $0 = about $30 a month. The big-order alert adds n8n (from $0 self-hosted) and a few cents of OpenAI usage. Shopify is already paid; a larger list moves you to a paid Mailchimp plan priced by contacts. Basis: Sum of the listed prices; your plans and volumes will differ.
Your time
- EAbout 1 to 2 hours a week to approve emails and send VIP thank-yous. Basis: Our estimate for a small business in its first month; measure your own in week 1.
Work out your own break-even
- Extra jobs needed to cover the tools = monthly tool bill / your average profit per job.
- Months to recover the setup = setup price ($1,500 founding, normally $2,500) / (extra profit a month from jobs you would have lost - monthly tool bill).
- Write down your baseline in week 1 and compare in week 4. Use your own numbers, not ours.

When to Stop
Baseline first. Before you start, write down how many customers bought again in the last 90 days and your repeat order share.
Day 30
- No replies or returning orders from the first two win-back rounds: change the reason to return, not the volume.
Day 60
- Unsubscribes rise faster than returning buyers: send less often and segment by product.
Day 90
- Returning orders from this do not cover the monthly tool bill: stop the win-back emails and keep the VIP alert.
E These thresholds are our rules of thumb, not benchmarks.
Rules to Follow
- Marketing email consentSend win-back and marketing emails only to customers who agreed to hear from you or who bought recently where the law allows, with a working unsubscribe in every email. In the EU and UK this falls under GDPR and the ePrivacy rules. Source.
- Email rules (US, CAN-SPAM)Commercial email needs a working opt-out, and people cannot be asked to pay or do more than reply or visit one page to opt out. Keep subject lines honest and include your postal address. Source.
- Data protection (EU and UK customers)If you hold personal data about people in the EU or UK, GDPR or UK GDPR applies: collect only what the job needs, tell people how you use it, and keep access to the connected accounts to the people who need it. Source.
- No income claimsNothing on this page promises income, savings or any business result. The value lines are labelled estimates with their basis. Bots draft and you approve. Source.
What Is Typical
- Caveat. We have no verified, independent data on win-back email results for small Shopify stores. Track your own returning buyers per round.
FAQ
Does it send emails automatically?
No. It drafts them in your email tool. You approve and send each round.
Do I need a paid Mailchimp plan?
Not under 250 contacts. Automation flows and larger lists need a paid plan; check the price for your list size.
