The Sheet remains the source
Your organization keeps the roster, segmentation, and message fields in its existing Google Workspace workflow.
FOR DPOs, IT TEAMS, AND PUBLIC INSTITUTIONS
Keep the roster in the Sheet.
Keep analytics out of the identity layer.
Sheet2Mail separates spreadsheet sovereignty from email delivery. Contact rows stay in Google Sheets, while campaign tracking uses one-way cryptographic hashes instead of storing recipient addresses in analytics.
DATA PROTECTION BRIEFINGv1.0
◆
A smaller data footprint
The sheet remains the working record. Reporting receives a verification token, not a readable address.
Ready for IT and legal review
THE DATA FLOW
A dispatch path your DPO can draw on one page.
The managed relay receives what it needs to deliver the message. Campaign analytics then identifies a message through a one-way hash, so the reporting layer does not need a readable recipient address.

Campaign analytics
One-way hash, opens, clicks
A hash is not a substitute for a complete privacy review. Use the briefing to document your own lawful basis, retention, access, and processor requirements.
WHAT CHANGES
Privacy by reducing what needs to travel.
Analytics sees a token
Opens and clicks are matched to a one-way hash. Reporting can work without a second readable contact directory.
Your delivery boundary is explicit
Choose your own SMTP server when infrastructure must remain in-house, or document the managed relay as a processor in your review.
THE DPO CHECKLIST
Give the internal advocate language they can reuse.
The downloadable briefing is deliberately short. It gives IT, procurement, and legal a common starting point before they assess the organization-specific details.

A SMALLER IDENTITY FOOTPRINT
Make the data flow easy to explain.
Sheet2Mail provides infrastructure. Your organization remains responsible for consent, lawful basis, retention, and the final compliance decision.
