The welcome discount — "10% off your first order" — is a staple for a reason: it gives a hesitating first-time visitor the small push they need to buy. But to work, it has to be limited to genuinely new customers and to one use each, or it turns into a permanent store-wide discount that existing customers exploit too.
Why the limits matter
Set up carelessly, a "first order" code gets used by repeat customers on every purchase, or shared until it's just a general discount. Configuring it to apply only to customers with no prior orders, one use each, takes a few specific settings in Shopify that are easy to miss.
Set it up correctly in one instruction

Claude scopes the code to first-time customers and caps it at one use each, so it does its job — converting new visitors — without leaking into discounts for people who'd have bought anyway.
Ways to get more from a welcome offer
Why it's worth running
A first-order discount lowers the barrier at the exact moment a new visitor is deciding whether to trust you. Because setting it up — and testing different versions — is now a single instruction, you can dial in the welcome offer that converts best for your store.
