Has Anyone Successfully Used Shopify Residential IP for Better Store Performance?

I was in the same boat as you—super unsure about shopify residential ip.
But after trying it out, I can say it’s worth it if you’re doing anything that requires multiple IPs.

I use Proxy-Seller, and it’s been reliable for my needs.
Just make sure you’re clear on what you’re using it for. It’s not a one-size-fits-all solution.
