Shopify Domain & Workspace Setup

I own a Shopify store and have just registered the primary domain on Namecheap. I now need that domain to resolve cleanly to my Shopify storefront, load securely over HTTPS, and power professional email through Google Workspace.

Here’s the exact scope I want covered:
• Connect my Namecheap domain to Shopify, including the appropriate A-records, CNAME, and any additional DNS entries Shopify requires.
• Provision and install the free SSL certificate so the storefront displays the padlock without mixed-content warnings.
• Configure Google Workspace: update MX, SPF, DKIM, and any other DNS records Google specifies, verify the domain, and create/activate the first user accounts.
• Confirm that sending and receiving email works from the new addresses and that the Shopify checkout, admin notifications, and any contact forms use the new domain email.

I’ll supply temporary access to Namecheap, Google Workspace admin, and my Shopify dashboard. Please send a brief proposal that outlines your step-by-step plan, approximate timeline, and anything you’ll need from me before you start. I’d like the whole setup completed smoothly in one session if possible, but let me know if you recommend staging it.
