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; Transcend value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Proton Mail

  • Encrypted email communicationnot Transcend
  • Privacy-focused email servicenot Transcend
  • Family email protectionnot Transcend

Transcend

  • A consumer app processing millions of user records that has to delete a user across a warehouse, a CRM, a support desk and three internal services within a statutory deadlinenot Proton Mail
  • A privacy team that currently fulfils requests by emailing system owners and wants machine evidence that deletion actually occurrednot Proton Mail
  • A company wiring consent signals through to advertising and analytics platforms so refused consent is honoured downstream rather than only at the bannernot Proton Mail
  • An organisation putting policy controls on which customer data models and internal agents may read, ahead of an AI governance auditnot Proton Mail

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

Transcend

  • Value is proportional to integration coverage, so every bespoke internal service needs a connector that your engineers build and then maintain, and the automation promise degrades quietly each time an internal API changes and nobody updates the connector.
  • Pricing is quoted and scales with data volume and integration count, so the cost grows precisely as the company grows, and there is no public anchor to negotiate against at renewal.
  • It is deep on fulfilment and consent but thinner than OneTrust on wider governance, third party risk and ethics programme management, so a large enterprise privacy office may end up running two vendors.
  • Deployment requires engineering time to install and authorise integrations into production data stores, which means the privacy team cannot buy and implement it alone and the project competes with engineering roadmap.
  • Automated deletion against production systems is a destructive operation, so organisations without good staging environments and confident data ownership move slowly and often run the tool in advisory mode for months before letting it execute.

Answered from the vendors’ own pages

Proton Mail: Is there a free version of Proton Mail?

Yes, Proton Mail offers a free plan with 1 GB storage, 1 encrypted email address, and basic features like folders, labels, and filters.

Source
Transcend: How is Transcend different from a subject request ticketing tool?

It executes the request against your systems through integrations rather than routing a task to a person. That is the whole product, and it is why the deployment requires engineering involvement.

Proton Mail: What does the Mail Plus plan include?

Mail Plus includes 15 GB storage, 10 encrypted email addresses, support for 1 custom domain, 10 hide-my-email aliases, priority support, and access to Proton Calendar.

Source
Transcend: What does it cost?

Nothing is published. Reported deals begin around 10,000 US dollars a year and rise with data volume, integration count and modules such as AI governance.

Proton Mail: What is included in Proton Unlimited?

Proton Unlimited provides 500 GB storage, 15 email addresses, 3 custom domains, unlimited hide-my-email aliases, access to Mail, Calendar, VPN, Drive, and Pass, plus dedicated support.

Source
Transcend: Can it replace OneTrust?

For subject rights, consent and data mapping, often yes. For third party risk, ethics reporting and wider GRC programme management it is narrower.

Proton Mail: Does Proton Mail offer a money-back guarantee?

Yes, Proton Mail provides a 30-day money-back guarantee for paid plans.

Source
Transcend: Does it handle unregistered systems?

It scans for personal data silos rather than relying solely on a declared inventory, which routinely surfaces systems the privacy register did not contain.
