In addition to (or instead of) an email provider recommended here, you may wish to consider a dedicated email aliasing service to protect your privacy. Among other things, these services can help protect your real inbox from spam, prevent marketers from correlating your accounts, and encrypt all incoming messages with PGP.
سرویسهای سازگار با OpenPGP
These providers natively support OpenPGP encryption/decryption and the Web Key Directory (WKD) standard, allowing for provider-agnostic end-to-end encrypted emails. به عنوان مثال، یک کاربر Proton Mail می تواند یک پیام E2EE را به یک کاربر Mailbox.org ارسال کند، یا می توانید اعلان های رمزگذاری شده با OpenPGP را از سرویس های اینترنتی که از آن پشتیبانی می کنند دریافت کنید.
{ .twemoji } Proton Mail
{ .twemoji } Mailbox.org
Warning
When using E2EE technology like OpenPGP your email will still have some metadata that is not encrypted in the header of the email, generally including the subject line! Read more about email metadata.
OpenPGP also does not support forward secrecy, which means if the private key of either you or the message recipient is ever stolen, all previous messages encrypted with it will be exposed.
Proton Mail
Proton Mail یک سرویس ایمیل با تمرکز بر حریم خصوصی، رمزگذاری، امنیت و سهولت استفاده است. They have been in operation since 2013. Proton AG is based in Geneva, Switzerland.
The Proton Free plan comes with 500 MB of Mail storage, which you can increase up to 1 GB for free.
:octicons-home-16: Homepage{ .md-button .md-button--primary } :simple-torbrowser:{ .card-link title="Onion Service" } :octicons-eye-16:{ .card-link title="Privacy Policy" } :octicons-info-16:{ .card-link title="Documentation" } :octicons-code-16:{ .card-link title="Source Code" }
Free accounts have some limitations, such as not being able to search body text and not having access to Proton Mail Bridge, which is required to use a recommended desktop email client (e.g., Thunderbird). حسابهای پولی شامل ویژگیهایی مانند Proton Mail Bridge، فضای ذخیرهسازی اضافی و پشتیبانی از دامنه سفارشی است. If you have the Proton Unlimited plan or any multi-user Proton plan, you also get SimpleLogin Premium for free.
A letter of attestation was provided for Proton Mail's apps on 9th November 2021 by Securitum.
Proton Mail has internal crash reports that are not shared with third parties. This can be disabled in the web app: ⚙️ → All Settings → Account → Security and privacy → Privacy and data collection.
:material-check:{ .pg-green } Custom Domains and Aliases
مشترکین Proton Mail پولی می توانند از دامنه خود با این سرویس یا آدرس catch-all استفاده کنند. Proton Mail also supports sub-addressing, which is useful for people who don't want to purchase a domain.
:material-check:{ .pg-green } روش های پرداخت خصوصی
Proton Mail accepts cash by mail in addition to standard credit/debit card, Bitcoin, and PayPal payments.
:material-check:{ .pg-green } امنیت حساب
Proton Mail supports TOTP two-factor authentication and hardware security keys using FIDO2 or U2F standards. The use of a hardware security key requires setting up TOTP two-factor authentication first.
:material-check:{ .pg-green } امنیت داده
Proton Mail دارای رمزگذاری بدون دسترسی برای سرویس ایمیل و تقویم است. داده های ایمن شده با رمزگذاری دسترسی صفر فقط توسط شما قابل دسترسی است.
برخی از اطلاعات ذخیره شده در Proton Contacts، مانند نامهای نمایشی و آدرسهای ایمیل، با رمزگذاری دسترسی صفر ایمن نمیشوند. فیلدهای مخاطبین که از رمزگذاری دسترسی صفر پشتیبانی می کنند، مانند شماره تلفن، با نماد قفل نشان مشخص می شوند.
:material-check:{ .pg-green } رمزگذاری ایمیل
Proton Mail دارای رمزگذاری OpenPGP یکپارچه در ایمیل خود است. ایمیلهای سایر حسابهای Proton Mail بهطور خودکار رمزگذاری میشوند و رمزگذاری آدرسهای ایمیل غیر پروتون با کلید OpenPGP به راحتی در تنظیمات حساب شما فعال میشود. Proton also supports automatic external key discovery with WKD. This means that emails sent to other providers which use WKD will be automatically encrypted with OpenPGP as well, without the need to manually exchange public PGP keys with your contacts. They also allow you to encrypt messages to non-Proton Mail addresses without OpenPGP, without the need for them to sign up for a Proton Mail account.
Proton Mail also publishes the public keys of Proton accounts via HTTP from their WKD. This allows people who don't use Proton Mail to find the OpenPGP keys of Proton Mail accounts easily for cross-provider E2EE. This only applies to email addresses ending in one of Proton's own domains, like @proton.me
. If you use a custom domain, you must configure WKD separately.
:material-information-outline:{ .pg-blue } بستن حساب
اگر یک حساب پولی دارید و صورتحساب شما پس از 14 روز پرداخت نشده است، نمیتوانید به دادههای خود دسترسی داشته باشید. پس از 30 روز، حساب شما معلق میشود و نامه های دریافتی را دریافت نمیکند. در این مدت صورتحساب شما ادامه خواهد داشت. Proton will delete inactive free accounts after one year. You cannot reuse the email address of a deactivated account.
:material-information-outline:{ .pg-blue } عملکردهای دیگر
Proton Mail's Unlimited plan also enables access to other Proton services in addition to providing multiple custom domains, unlimited hide-my-email aliases, and 500 GB of storage.
Mailbox.org

:material-check:{ .pg-green } دامنه ها و نام های مستعار (Aliases) سفارشی
Mailbox.org lets you use your own domain, and they support catch-all addresses. Mailbox.org also supports sub-addressing, which is useful if you don't want to purchase a domain.
:material-check:{ .pg-green } روش های پرداخت خصوصی
به دلیل تعلیق پرداختیار BitPay در آلمان، Mailbox.org هیچ ارز دیجیتالی را نمیپذیرد. However, they do accept cash by mail, cash payment to bank account, bank transfer, credit card, PayPal, and a couple of German-specific processors: Paydirekt and Sofortüberweisung.
:material-check:{ .pg-green } امنیت حساب
Mailbox.org supports two-factor authentication for their webmail only. You can use either TOTP or a YubiKey via the YubiCloud. Web standards such as WebAuthn are not yet supported.
:material-information-outline:{ .pg-blue } امنیت داده
Mailbox.org allows for encryption of incoming mail using their encrypted mailbox. پیام های جدیدی که دریافت میکنید بلافاصله با کلید عمومی شما رمزگذاری میشوند.
However, Open-Xchange, the software platform used by Mailbox.org, does not support the encryption of your address book and calendar. A standalone option may be more appropriate for that data.
:material-check:{ .pg-green } رمزگذاری ایمیل
Mailbox.org has integrated encryption in their webmail, which simplifies sending messages to people with public OpenPGP keys. They also allow remote recipients to decrypt an email on Mailbox.org's servers. این ویژگی زمانی مفید است که گیرنده امکان استفاده از OpenPGP را ندارد و نمی تواند یک کپی از ایمیل را در صندوق پستی خود رمزگشایی کند.
Mailbox.org also supports the discovery of public keys via HTTP from their WKD. This allows people outside of Mailbox.org to find the OpenPGP keys of Mailbox.org accounts easily for cross-provider E2EE. This only applies to email addresses ending in one of Mailbox.org's own domains, like @mailbox.org
. If you use a custom domain, you must configure WKD separately.
:material-information-outline:{ .pg-blue } بستن حساب
Your account will be set to a restricted user account when your contract ends. It will be irrevocably deleted after 30 days.
:material-information-outline:{ .pg-blue } عملکردهای دیگر
You can access your Mailbox.org account via IMAP/SMTP using their .onion service. However, their webmail interface cannot be accessed via their .onion service, and you may experience TLS certificate errors.
All accounts come with limited cloud storage that can be encrypted. Mailbox.org also offers the alias @secure.mailbox.org, which enforces the TLS encryption on the connection between mail servers, otherwise the message will not be sent at all. Mailbox.org همچنین از Exchange ActiveSync علاوه بر پروتکلهای دسترسی استاندارد مانند IMAP و POP3 پشتیبانی میکند.
Mailbox.org امکان به ارث بردن اطلاعات برای همه طرحهایش را دارد. You can choose whether you want any of your data to be passed to heirs, providing that they apply and provide your testament. همچنین میتوانید فردی را با نام و آدرس معرفی کنید.
سرویس دهندگان بیشتر
این ارائه دهندگان ایمیل های شما را با رمزگذاری دانش صفر (zero-knowledge encryption) ذخیره می کنند که آنها را گزینههای خوبی برای ایمن نگه داشتن ایمیل های شما میکند. با این حال، آنها از استانداردهای رمزگذاری E2EE بین ارائه دهندگان مختلف ایمیل پشتیبانی نمیکنند.

معیار
Please note we are not affiliated with any of the providers we recommend. In addition to our standard criteria, we have developed a clear set of requirements for any email provider wishing to be recommended, including implementing industry best practices, modern technology and more. We suggest you familiarize yourself with this list before choosing an email provider, and conduct your own research to ensure the email provider you choose is the right choice for you.
فناوری
We regard these features as important in order to provide a safe and optimal service. You should consider whether the provider has the features you require.
حداقل شرایط صلاحیت:
- Must encrypt email account data at rest with zero-access encryption.
- Must be capable of exporting emails as Mbox or individual .EML with RFC5322 standard.
- Allow users to use their own domain name. Custom domain names are important to users because it allows them to maintain their agency from the service, should it turn bad or be acquired by another company which doesn't prioritize privacy.
- Must operate on owned infrastructure, i.e. not built upon third-party email service providers.
بهترین حالت:
- Should encrypt all account data (contacts, calendars, etc.) at rest with zero-access encryption.
- Should provide integrated webmail E2EE/PGP encryption as a convenience.
- Should support WKD to allow improved discovery of public OpenPGP keys via HTTP. GnuPG users can get a key with this command:
gpg --locate-key example_user@example.com
. - Support for a temporary mailbox for external users. This is useful when you want to send an encrypted email without sending an actual copy to your recipient. These emails usually have a limited lifespan and then are automatically deleted. They also don't require the recipient to configure any cryptography like OpenPGP.
- Should support sub-addressing.
- Should allow users to use their own domain name. Custom domain names are important to users because it allows them to maintain their agency from the service, should it turn bad or be acquired by another company which doesn't prioritize privacy.
- Catch-all or alias functionality for those who use their own domains.
- Should use standard email access protocols such as IMAP, SMTP, or JMAP. Standard access protocols ensure customers can easily download all of their email, should they want to switch to another provider.
- Email provider's services should be available via an onion service.
حریم خصوصی
ما ترجیح میدهیم ارائهدهندگان پیشنهادی ما تا حد امکان دادههای کمی جمعآوری کنند.
حداقل شرایط لازم:
- Must protect sender's IP address, which can involve filtering it from showing in the
Received
header field. - Must not require personally identifiable information (PII) besides a username and a password.
- Privacy policy must meet the requirements defined by the GDPR.
بهترین حالت:
- Should accept anonymous payment options (cryptocurrency, cash, gift cards, etc.)
- Should be hosted in a jurisdiction with strong email privacy protection laws.
امنیت
Email servers deal with a lot of very sensitive data. We expect that providers will adopt industry best practices in order to protect their customers.
حداقل شرایط لازم:
- Protection of webmail with 2FA, such as TOTP.
- Zero-access encryption, which builds on encryption at rest. The provider does not have the decryption keys to the data they hold. This prevents a rogue employee leaking data they have access to or remote adversary from releasing data they have stolen by gaining unauthorized access to the server.
- DNSSEC support.
- No TLS errors or vulnerabilities when being profiled by tools such as Hardenize, testssl.sh, or Qualys SSL Labs; this includes certificate related errors and weak DH parameters, such as those that led to Logjam.
- A server suite preference (optional on TLS 1.3) for strong cipher suites which support forward secrecy and authenticated encryption.
- A valid MTA-STS and TLS-RPT policy.
- Valid DANE records.
- Valid SPF and DKIM records.
- Must have a proper DMARC record and policy or use ARC for authentication. If DMARC authentication is being used, the policy must be set to
reject
orquarantine
. - A server suite preference of TLS 1.2 or later and a plan for RFC8996.
- SMTPS submission, assuming SMTP is used.
- Website security standards such as:
- HTTP Strict Transport Security
- Subresource Integrity if loading things from external domains.
- Must support viewing of message headers, as it is a crucial forensic feature to determine if an email is a phishing attempt.
بهترین حالت:
- Should support hardware authentication, i.e. U2F and WebAuthn.
- DNS Certification Authority Authorization (CAA) Resource Record in addition to DANE support.
- Should implement Authenticated Received Chain (ARC), which is useful for people who post to mailing lists RFC8617.
- Published security audits from a reputable, third-party firm.
- برنامههای باگبانتی و/یا فرایند هماهنگ افشای آسیبپذیری.
- Website security standards such as:
اعتماد
You wouldn't trust your finances to someone with a fake identity, so why trust them with your email? ما از ارائهدهندگان پیشنهادی خود میخواهیم که مالکیت یا رهبری خود را بهصورت عمومی اعلام کنند. ما همچنین مایلیم گزارشهای شفافیت مکرر، بهویژه در مورد نحوه رسیدگی به درخواستهای دولت، مشاهده کنیم.
حداقل شرایط لازم:
- رهبری یا مالکیت قابل رویت توسط عموم.
بهترین حالت:
- گزارشهای شفافیت متناوب.
تبلیغات و بازاریابی
With the email providers we recommend, we like to see responsible marketing.
حداقل شرایط لازم:
- Must self-host analytics (no Google Analytics, Adobe Analytics, etc.).
- Must not have any irresponsible marketing, which can include the following:
- Claims of "unbreakable encryption." Encryption should be used with the intention that it may not be secret in the future when the technology exists to crack it.
- Guarantees of protecting anonymity 100%. When someone makes a claim that something is 100%, it means there is no certainty for failure. We know people can quite easily de-anonymize themselves in a number of ways, e.g.:
- Reusing personal information e.g. (email accounts, unique pseudonyms, etc.) that they accessed without anonymity software such as Tor
- اثر انگشت مرورگر
بهترین حالت:
- Clear and easy-to-read documentation for tasks like setting up 2FA, email clients, OpenPGP, etc.
قابلیتهای اضافی
While not strictly requirements, there are some other convenience or privacy factors we looked into when determining which providers to recommend.
