Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 29 of the 122 other email apps we grade
CTemplar is a webmail service that encrypts messages in the browser with OpenPGP and says it cannot read what its users send. Accounts can be opened without a phone number or credit card. It sells five tiers, from an invitation-only free mailbox up to a 50 GB plan.
To get you started, here are 9 things to know about CTemplar, taken from its own pages and our grades.
You set up a mailbox and decide what to encrypt, and the Monero payment goes through support.
- 1
Best for encrypted email hosted in Iceland
The free plan has no aliases or custom domains, and the encryption runs in your browser through JavaScript.
- 2
Paid plans start at $8 a month
As its pricing page puts it: $8 per month.
- 3
There is a free plan
Free plan, by invitation: 1 GB storage, 200 sent emails a day, 10 MB attachments, no aliases and no custom domains.
- 4
It runs on 3 platforms
Web, iOS and Android.
- 5
Encrypted subject, body and attachments
Messages are encrypted with OpenPGP.js in the browser, and the vendor says it does not hold the password to the private keys.
- 6
Anonymous sign-up and IP stripping
No phone number or credit card is needed to register, and the vendor says it replaces the sender's IP with its own on outgoing mail.
- 7
Self-destructing and delayed messages
Self-destruct, dead-man timer, delayed delivery and remote encrypted links are on every paid tier but not the free one.
- 8
A 2.2 GPA, above 29 of 122
That is against the other email apps we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace CTemplar you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for encrypted email hosted in Iceland
CTemplar is encrypted email hosted in Iceland, with a free plan by invitation and paid plans from $8 a month. The free plan has no aliases or custom domains, and the encryption runs in your browser through JavaScript.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Prime is $8 a month, about the middle of what email services charge. Higher tiers run to $50. |
| Free plan and trial | C | A free plan with 1 GB, 200 sent a day and 10 MB attachments, but it's by invitation and has no aliases or custom domains. |
| Features | C | Encrypted subject, body and attachments, self-destructing mail and aliases. The free plan lacks aliases and self-destruct, and the free tier leaves out the headline extras. |
| Ease of use | C | No store rating on record. You set up a mailbox and decide what to encrypt, and the Monero payment goes through support. |
| Platforms and integrations | B | Web, iPhone and Android apps. No desktop app is released, with Linux, macOS and Windows builds only in testing. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who CTemplar is for
- Fits if you want an encrypted mailbox and will pay for a custom domain
- Works for people who want to sign up without handing over personal details
Who it is not for
- Skip it if you want open sign-up on the free plan, since it's invitation only
- Tight if you stay free: no aliases, no custom domains and no self-destructing mail
- Pricey if you need more than one domain, as Knight is $12 a month and Marshal $20
- Watch out: encryption runs in the browser with JavaScript, which the site says is required
- Watch out: desktop builds are only in testing
Good to know
Good for
- People who want a mailbox opened without a phone number or card
- Anyone who wants Monero, Bitcoin or card payment options for email
- Users who value an Iceland-based provider
Worth knowing
- The free plan is by invitation, so it is not open sign-up, and it has no aliases and no self-destructing email.
- Encryption runs in the browser with JavaScript, which the site says is required.
- Monero payments are handled through support rather than automatically; Bitcoin and card payments are automatic.
- The vendor lists Linux, macOS and Windows desktop builds as being tested, not released, so only web, App Store and Google Play access is confirmed.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace CTemplar you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 69 of the 122 other email apps grade higher. It costs $96 a year. CTemplar is open source, so there is a third way: take its code and run it yourself.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- A real app for iOS and Android. Something home-made would be a web page.
- End-to-end encryption done properly.
What this rests on. CTemplar’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
