Assumptions

  • Google Workspace (workspace.google.com/pricing, EUR as shown in Greece, taxes extra, read 9 Nov 2026): Business Starter €8.10 per user per month on the Flexible plan, €6.80 with a 1-year commitment; Business Standard €16.20 / €13.60; Business Plus €25.30 / €21.10 (choose the plan in the selector above). The introductory offer for new customers (50% off for the first months, first 20 users) is not used. Business plans are limited to 300 users; Enterprise is quoted.
  • Proton Mail for Business (proton.me/business/mail/pricing, EUR, taxes may apply, read 9 Nov 2026): Mail Essentials €7.99 per user per month billed monthly, €6.99 billed yearly, with 15 GB per user and 3 custom domains. Proton's Workspace Standard (€14.99 monthly) and Premium (€24.99) bundles add Drive, Meet, VPN and the password manager; their yearly prices are shown only as a 40% launch offer to 30 Nov 2026 and are not modelled. With the currency set to USD the same page shows $7.99 / $6.99, and the tool uses those prices when amounts are shown in USD (Google Workspace is then converted from EUR). Against Business Starter the price gap is small, so the decision is about end-to-end encryption, Swiss jurisdiction and the apps your team uses, not price; storage per user also differs (30 GB vs 15 GB).

Sources

CSV header mapper

Rename exported Google Workspace column headers to suggested Proton Mail for Business column names, for reporting or manual data preparation. Not an official Proton Mail for Business import format. It runs in your browser. Headers are renamed and the values in kept columns stay unchanged; columns that look like passwords or other secrets are removed.

Renamed headers do not make a file import-ready. Check whether and how Proton Mail for Business accepts such data before importing, and create any custom fields there first.
