Support mail is full of half-typed identifiers: an order number missing a digit, a checkout email that differs from the sending address, a tracking reference pasted out of a carrier page. Codex is at its best on concrete, well-scoped work and on handling exactly that kind of structured data, which is most of what happens between the email arriving and the draft appearing. The writing itself is the short part of the run.
Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.
Order 10482 tracking has not updated in six days
Hi, I ordered the winter cycling jacket on 28 July and the tracking has said in transit at the Oslo sorting centre since 3 August. I paid for express delivery because I need it for a trip on 16 August. Could you check whether the parcel is actually moving, and send a replacement in the same size if it is lost? The order number is 10482.
Using this template drops you into a guided setup. It asks exactly this, nothing else:
Connect Gmail
One sign-in. The agent acts through your account, scoped to what this template uses.
Connect Shopify
One sign-in. The agent acts through your account, scoped to what this template uses.
Store name
The name your customers know your store by, used in greetings and sign-offs so every draft reads like it came from your team.
Support policies
Your shipping, returns, refunds, exchange and cancellation rules in your own words, with the timelines and the things you never do. The agent only ever quotes policy from this.
Runs on Codex
Preselected for this page — connect your Codex account during setup, or switch to NoClick's built-in models with one click.
Watch it handle a test run
A staged conversation against a simulated world — then it’s live.
Matching a quoted reference to a real Shopify order, then falling back to a customer lookup by email address when it does not resolve, is the concrete API work this harness is strong at.
The chain is short and defined: find the order, check fulfillment, write four short paragraphs. Nothing about it rewards deliberation as much as it rewards being ready before the customer writes again.
You bring the model credential, either a ChatGPT plan or an OpenAI API key, and Codex uses it on every run. Your Shopify and Gmail connections are held separately in NoClick. None of it is visible to the customer, since the reply still leaves from your own address when you press send.
Free to start. Guided setup, a test run against staged conversations, and it's live.
