Free gift without purchase after Form Completion

Topic summary

Goal: Offer a free gift (no purchase required) as an incentive for opting in to marketing communications.

Desired flow: After a customer submits a Shopify “Contact Us”-style form, the submit action should redirect straight to checkout with the free gift preloaded, allowing the customer to enter their address and complete a normal order.

Additional requirement: Include an upsell (i.e., offer additional products) within this checkout flow.

Key question: Can this be implemented with native Shopify functionality, or is a third‑party app required?

Status: No solutions or confirmations provided; the inquiry remains open with no decisions or next steps recorded.

I’d like to offer customers a free gift (no purchase necessary) as an opt-in incentive, if they sign up to receive marketing communications from us. Once they have completed the Form (Contact Us style page), I’d like the submit button to then link through straight to the checkout page containing the free gift for them to enter their address information etc to process as a normal order?

Ideally I’d like to offer an upsell as part of this also.

Is this possible using Shopify or an app?
