Add Newsletter Marketing Checkbox inside the new Login Page

Topic summary

Goal: Add a newsletter opt-in checkbox to the customer account creation flow so new customers can subscribe during signup.

Context: Store uses the Crave theme (15.1.0) and Shopify’s new passwordless login (email verification code). The request is to place a marketing consent checkbox in that new login/sign-up form.

Input so far: One reply suggests using a marketing platform’s newsletter form, implying an external solution, but provides no steps or specifics.

Clarification needed: The original poster asks whether a third‑party app is required and requests elaboration on how to implement the checkbox.

Notes: The attached screenshot illustrates the new login UI but isn’t critical to understanding. “Newsletter checkbox” refers to capturing marketing email consent at signup.

Status: No implementation details, code, or concrete solution provided yet. Key open questions: Can this be done via theme customization alone, or is a marketing platform/app required, and what are the exact steps to integrate it?

Hello dear shopify community!

I would like to add a Newsletter Marketing Checkbox (new Login Form), so that if a customer creates a new account, they can sign up to the newsletter.

I’m using the Crave Theme 15.1.0 and the new Login Form (no password required, just email with verification code).

Any help is appreciated!
