Opt-in shipping protection waits for the customer to tick a box. Auto-add puts protection in the cart by default and lets the customer remove it. Both are common on Shopify. The right choice depends on how much you value a higher attach rate against the risk of customers feeling surprised by a charge.

What is the difference?
| Opt-in | Auto-add | |
|---|---|---|
| Default state | Off; customer adds it | On; customer can remove it |
| Attach rate | Lower | Usually higher |
| Customer surprise | Low | Higher if disclosure is weak |
| Disclosure needed | Clear price and coverage | Clear price, coverage, “optional” label, easy removal |
| Best for | Stores focused on trust, first-time buyers | Stores with loyal customers and high loss rates |
Why does auto-add raise attach rate?
People tend to keep defaults. When protection is already in the cart, customers who would not have gone looking for it often leave it there. That raises protection revenue, and more protected orders means more customers with a clear path when a package goes missing.
What are the risks of auto-add?
- Surprise charges. A customer who notices an unexpected line item may lose trust or abandon checkout.
- Support load. Some customers ask for the fee to be refunded after the fact.
- Fee rules. Hidden-fee rules are tightening. Optional fees are generally treated differently from mandatory ones, but Massachusetts, for example, requires optional fees to be disclosed as optional with instructions to avoid them. See our guide to junk fee rules and shipping protection.
How do you auto-add transparently?
- Show the fee and what it covers next to the toggle, before payment.
- Label it clearly as optional.
- Let customers remove it with one click, at any point before paying.
- Link your protection policy.
- Show it as its own line item on the order and receipt.
Where should the toggle go?
Placement matters as much as the default. Put the protection toggle next to the cart subtotal and in the cart drawer, where customers check the total before paying. A second, post-purchase offer on the thank-you page catches customers who skipped it, without adding friction before payment. Whatever you choose, keep the wording and price identical everywhere it appears.
How should you test opt-in vs auto-add?
Run each version for the same length of time, ideally three to four weeks, and change nothing else. Then compare:
- Fee revenue minus claims, the number that actually matters.
- Checkout conversion rate, to catch any drop from surprised shoppers.
- Support tickets about the protection fee.
- Attach rate, as context rather than the goal.
If auto-add raises revenue without hurting conversion or creating complaints, keep it. If conversion dips or tickets rise, go back to opt-in and improve placement and wording instead. Our guide on how much to charge for shipping protection explains how price and attach rate interact, and the shipping protection calculator shows the revenue effect.
What does Sam support?
Sam Shipping Protection can show protection as an opt-in toggle or add it to eligible carts automatically. Either way, the price is visible, customers can remove it before paying, and it appears as a separate line on the order.
Frequently asked questions
Is auto-add shipping protection allowed?
Many stores use it, but it must be clearly optional. Show the fee before payment, label it optional and make it one click to remove. Some states set extra rules for optional fees, such as Massachusetts, which requires them to be disclosed as optional with instructions to avoid them.
Does auto-add increase revenue?
It usually increases the share of customers who keep protection, because many shoppers leave defaults as they are. Test it: compare total fee revenue and complaints over the same period, not just attach rate.
Can Sam auto-add shipping protection?
Yes. Sam can add protection to eligible carts automatically, and customers can remove it before paying.
