Secondary domain redirects to a page within primary domain

Topic summary

Goal: Point a secondary Shopify domain (redrootknives.com) to a specific page on the primary store (redrootblades.com/pages/newsletter) while keeping the secondary domain visible in the browser (URL masking), ideally as redrootknives.com or redrootknives.com/pages/newsletter.

Current setup: redrootblades.com is the primary domain and storefront. redrootknives.com currently redirects to the primary root domain.

Desired behavior: Users entering redrootknives.com should land directly on /pages/newsletter on the primary site, without the URL switching to redrootblades.com.

Constraint/question: The author can’t find a native Shopify setting to achieve a path-based redirect with domain masking and suspects it may require third‑party domain management (as they had previously). They ask if this is possible within Shopify or not.

Status: Unresolved; seeking confirmation or a method to implement path-level redirect and URL masking using Shopify-managed domains.

I have two domains registered with Shopify: redrootblades.com and redrootknives.com.

redrootblades.com is my primary domain and shop. Currently redrootknives.com just redirects to redrootblades.com.

What I want to do:

I want to redirect “redrootknives.com” to the page www.redrootblades.com/pages/newsletter and also just show “redrootknives.com” or “Newsletter – Redroot Blades” as the url.

So, users would type in “redrootknives.com” and they would be directed to Newsletter – Redroot Blades and ideally, the url would show redrootKNIVES not blades.

Haven’t found an answer on the community yet. It almost seems like I’d need to register redrootknives.com with a third party to do this redirect. When all my domains were with a third party, this type of redirection was easy. Is it really not possible within Shopify?

Thanks,

Dustin
