The short version

  • Only Proton Mail has a free tier, so it costs nothing to try first.
  • Each has a real cost: Proton Mail paid plan pricing not displayed on vendor site; Yoti age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Proton Mail

  • Paid plan pricing not displayed on vendor site
  • Free tier limited to 1 GB storage
  • Free tier limited to single email address

Yoti

  • Age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • Estimation accuracy varies by demographic and reported error margins widen at the age bands that matter most for eighteen-year thresholds, which pushes borderline users into a document fallback you still have to pay for.
  • Pricing is not published, so buyers cannot compare the cost of an estimation check against a document check without going through sales.
  • Regulatory acceptance of facial estimation differs by jurisdiction, so a method that satisfies Ofcom may not satisfy a regulator elsewhere and multi-market platforms need more than one approach.
  • The reusable digital identity app depends on consumer adoption, which is meaningful in the UK and thin elsewhere, limiting the reusability benefit outside its home market.
