A Shopify app that drafts your support replies for you.

The challenge

Small Shopify stores can't afford a support team — or another inbox.

Independent Shopify merchants spend an outsized chunk of their day answering the same five questions: where's my order, can I return this, do you wholesale, what's the size guide, can I change my address. Off-the-shelf support tools either cost more than the merchant's margin per order, or behave like a help-desk built for a 50-person team.

The brief: a tool a one-person store could turn on in a minute, that drafts replies in their voice, and never sends anything they didn't approve. Cheap enough to be a no-brainer. Honest enough to build trust through the first hundred replies.

The approach

A single workspace, shaped around a single nervous merchant.

MailMind connects to Gmail via a single OAuth click from inside Shopify Admin. It scans the store's products, policies, and past replies to build a voice profile in about 45 seconds — tone, length, sign-off, words to avoid. New support emails get a drafted reply within seconds. Promotional blasts, carrier notifications, and personal mail are skipped automatically so the draft queue stays clean.

Auto-send is opt-in per category. A merchant can flip it on for shipping questions while keeping returns and wholesale always-drafted. Every reply logs to the Shopify admin so the merchant can audit exactly what went out. Backend, app surface, and marketing site were all built in-house, on a stack we can stand behind.

"Draft mode by default. Nothing sends without your tap. You're the final editor, always."
MailMind product principle

The result

A pre-launch product with the marketing site live and the App Store review pending.

The marketing site is live at mailmind.space, collecting early-access signups while the app waits in the Shopify App Store review queue. Pricing is the simplest line in the deck: $19 per month, billed through Shopify, seven days free, cancel any month.

The product surface is intentionally small — connect Gmail, train voice, set per-category auto-send rules. Nothing else. The bet is that small merchants will pay for a tool that fits, not a platform that almost fits.
