Weekly Zoho to Google Email Sync

I need a reliable way to copy new Zoho Mail inbox messages into my Google Workspace inbox once a week. Only incoming email has to move—sent items or attachments aren’t required—so the solution can stay lean.

Ideally, you’ll automate the transfer through native APIs, Zoho Flow, Zapier, or a lightweight script running on a schedule. Whichever method you choose, it must:

• Pick up every new inbox message in Zoho
• Create the same message in the matching Gmail account (headers, body, and basic metadata intact)
• Run automatically on the weekly interval without manual triggers
• Provide a simple log so I can confirm each sync completed successfully

Please outline the approach, tools, and any access prerequisites in your proposal. A quick test proving the weekly sync works will be the final acceptance step.
