Our verdict
Tuta is the pick for readers who want a private mailbox rather than a full office suite, and it leads this comparison on whole-mailbox encryption. It runs apps on Android, iOS and Windows, sits under DE jurisdiction, and holds ISO 27001. A free plan is included, with limits worth reading before you sign up.

Pros and cons
Pros
- End-to-end encryption covers the whole mailbox, including subject lines, headers, calendar, contacts and drive data, with external recipients handled through a shared password
- A free plan is included, and its limits are spelled out plainly as 1 GB storage, 1 calendar, 3 labels, no custom domains
- The provider cannot read your mail, calendar or drive data, since encryption is built so no readable copy sits on their side
- Open source, and the apps cover Android, iOS and Windows
Cons
- The free plan is tight, with limits of 1 GB storage, 1 calendar, 3 labels, no custom domains
- Support runs on email, help centre and community only
- Mail server logs are kept for a short window and IP addresses are stored only in anonymized form, so tracing is limited rather than absent
Who it suits
- Readers who want one encrypted home for mail, calendar, contacts and drive rather than separate tools
- People already inside an Apple setup who want an account that does not depend on a big platform ecosystem
- Anyone happy to start on a free plan and read the limits in 1 GB storage, 1 calendar, 3 labels, no custom domains before paying
Who should look elsewhere
- Teams that need shared mailboxes and admin controls, since this is a personal account rather than a managed work suite
- People who want phone support, because support runs on email, help centre and community
- Readers who need a large free allowance, because the free plan is capped at 1 GB storage, 1 calendar, 3 labels, no custom domains

Frequently asked questions
Does Tuta have a free plan?+
Yes, a free plan is included. Its limits are 1 GB storage, 1 calendar, 3 labels, no custom domains, and the storage allowance on it is 1. That makes it usable as a trial rather than a long-term home, and the same limits sit next to the price on the pricing page.
What does end-to-end encryption cover on Tuta?+
It covers the whole mailbox, not just message bodies. That includes email, subject lines, headers, calendar, contacts and drive data. External recipients are reached through a shared password rather than a weakened key exchange.
Where is Tuta based and which law applies?+
The company is registered as Tutao GmbH, and its headquarters country is DE. The jurisdiction is DE, so German and EU data protection rules frame how the service is run. The company was founded in 2011.
Which platforms can I use Tuta on?+
There are apps for Android, iOS and Windows, so the same account works across desktop, mobile and browser. Custom domains are supported, which matters if you want to keep an address on a domain you own rather than the default one.
What does Tuta keep in its logs?+
Mail server logs are kept for a short window, and IP addresses are stored only in anonymized form. There are no cookies, and anonymized usage statistics are opt-in. Combined with whole-mailbox encryption, that keeps readable content off the provider's side.
Is Tuta open source and certified?+
Open source is stated for the service, and the listed compliance certification is ISO 27001. The legal entity behind it is Tutao GmbH, operating under DE jurisdiction, which is worth weighing against services that publish no such detail.
How can I get help from Tuta?+
Support runs on email, help centre and community, so answers come over email, a help centre and a community. If quick spoken help matters to you, that channel is the gap to check before you commit to a paid plan.
