15 Best And Most Secure Email Providers

With the rise in technology, various features and other advances have made communication easier. Moreover, email is seen as the best and most professional way of communicating for business. 

However, along with its pros, there are several other cons. The majority of them are privacy-related issues. If you wonder whether your emails are secure and encrypted, there is a high possibility that they are not. 

Hence, there are a few secure email providers and ways that you can make sure that all your emails are secure and encrypted. One of the ultimate ways is by changing your email provider.

Even though there are various email providers on the internet, you must know which one of them provides the best features and, at the same, guarantees the security of the communication.

Government Privacy Policies

Several government policies pose a threat to society as they have an easy way to access citizens’ data and other information. This can easily be done through several internet activities and emails. 

This is one of the main reasons why having a secure email provider is integral. Using mainstream and popular email services might lead you to more danger. You must have noticed several ads that you get based on one search history. 

This is mainly because all your internet activity is being tracked, and the conversations and emails are exposed to the server and others as well. It is integral for you to keep your email and other chats secure; this is why end-to-end encryption is significant. 

Along the same lines, several activists have also protested against the privacy policies present under numerous governments. There are quite a handful of email servers based in Switzerland and other countries with strict privacy policies. 

Hence, using email services based in those countries is considered very safe. 

Factors To Consider Before Using An Email Service

As mentioned earlier, there are several email providers on the internet, and it might be difficult to choose the right one. Hence, if you are planning on creating a new email account or switching to a different email provider, here are a few factors that you have to consider before you choose one. 

Along with encryption, there are also security, privacy, and jurisdiction that you will have to keep in mind while creating an account with a certain email service. Once you can protect the email communication, all your data and other activities will also automatically be kept safe by the provider.

There are several reasons why you should create a new account with a secure email provider. A majority of them are for security reasons and added features as well. 

1. Encryption

First off, you will have to check whether the email service provides encryption or not. The entire chain of communication should be end-to-end encryption. Moreover, this helps in keeping not only the communication but also all other attachments secure. 

At certain times, the sender, their email headers, and other email content are also not safe. Email providers that support IMAP and other end-to-end encryption are very integral. 

2. Better Privacy

Using secure email service providers based in privacy-friendly countries is the simplest way to ensure data privacy. Since there are no mandatory data retention laws in such countries, providers guarantee maximum data security, often with zero access, which they can easily follow. 

As a result, you can be confident that neither your government nor any other surveillance authorities will ever have access to your emails. 

3. Location of the service

Additionally, it would help if you saw where the email service is located. This will provide you with an idea of where the data is collected. Once you are aware of the service’s location, how your data gets affected by it is something that will help you if there is any problem.

4. Policies and standards of the email provider 

Along with the jurisdiction, you will also have to understand the email service’s policies and standards. This will also allow you to know where and how the data is saved. If you have understood the service policies, it will be easier to know whether your data is getting saved or not and for how long they store it. 

5. Features

Most email services provide several features to the users about files, contacts, calendars, and such. Due to this reason, checking the collaboration tools and other features that the email service provides is very integral. 

Importing all your existing contacts and emails to the one you are currently using is also essential. PGP is generally used to increase the security of the emails and provide encryption. Hence, if the email provider can provide all these features along with good privacy and security, you can go ahead and start using the same. 

6. Two-factor Authentication

This is yet another integral part of a secure email provider. With the help of two-factor authentication, hackers, or anyone, will not be able to log in to your email account just by entering the password. 

It is important to enter additional information, which could either be through a recovery email address or a phone number. The code sent to either of these should be entered first to log in to the account. 

Only if this is done will the user gain access to the account. Hence, if the email providers have the option of two-factor authentication, it becomes much safer for the users to access their accounts and secure their data. 

7. Metadata Tracking

While regular email services such as Yahoo and Gmail allow you to encrypt your emails, you are vulnerable due to insecure metadata. However, your metadata may not contain your entire message. 

It does, however, include other important details such as the sender’s information, timestamps, and the overall gist of your message. Despite encryption, anyone accessing this data with malicious intent can still get a sense of your email. 

As a result, using secure email services is preferable because it conceals your metadata completely. 

How To Keep Your Emails Safe And Private

If you use a secure messaging service with end-to-end encryption, you’ve taken an important step toward making your communications truly secure and private. You can take a few extra precautions even after choosing a particular secure email provider. 

You should be aware that certain software captures what you type directly from your keyboard.  A majority of the time, hackers will only require your password so that they can access your account. 

During those times, if they use software like the keyloggers, encryption will no longer play an important role, as hackers will easily be able to get access. 

Another integral point that you have to keep in mind is that you should leave either your phone or computer unattended in no situation. You have to ensure that all your devices have either strong passwords or other biometric data that will be difficult to get through. 

Not allowing unprotected or guest accounts will block access, and there are fewer chances of your phone being hacked or data getting stolen. It would help if you also kept an eye on social engineering. 

Certain phishing attempts can be made frequently through instant messaging, social media, or emails. Most of the time, hackers can carefully curate such attempts so that they will go unnoticed for a long time until the damage has been done. 

You should also not share any password or even write it down, for that matter. Writing down the passwords of emails that can easily be decrypted will make it easier for others to access your account.

Hushmail is also one of the most secure mail providers with proper encryption services. They generally use an OpenPGP protocol so that all the emails are confidential. It is a very easy application to use and one of the simplest. It can also be used on a mobile device and is considered one of the best secure email providers. 

They also have the feature of sending and securely receiving emails even if the other recipient is not using Hushmail. Moreover, another great feature of this email provider is that before you send it to a different email recipient, you will be asked additional security questions so that the entire chain is encrypted. 


Since it is regarded as one of the simplest email providers, creating an account and logging in is also very simple. After logging in to your account, you can easily access your account, either from the desktop itself or the phone application. 

Additionally, there are different plans available. There is a free version and five other paid versions that serve different purposes. They include personal, small businesses, healthcare, law, nonprofits, and enterprise. A majority of these paid versions have storage up to 10 or 15GB. 

Personal- This version provides 10GB storage, two secure web forms, and several layers of security. It also provides ad-free accounts with unlimited email aliases.

These are some of the available versions, and along with that, users can opt for a free account if it is for personal use. 

3. StartMail

StartMail is slightly different from the rest of the email providers. One of the main reasons is that it only uses Pretty Good Privacy instead of end-to-end encryption. However, this email provider consists of two-factor authentication, and overall the data is protected by the Dutch privacy laws. 

However, you will have to keep in mind that there is no free service, and before committing to this provider, you can take the seven-day trial. This provider also allows its users to access disposable anonymous email aliases, which are completely unlimited. 


The email storage that a user gets is about 10GB, and the paid version starts from $2.50 a month. Moreover, you cannot access the email from a mobile application, and you will have to use the desktop version itself or create a shortcut browser to your email on the phone. 

One more noteworthy feature of this email provider is that none of the ads is forced, which would mean your email activities are not tracked either. The only downside of this particular email provider is that they do not provide free versions; however, they do provide a free trial for seven days. 

4. Countermail

CounterMail provides safe and proper support to the users, and there is no need to pay for the provider at all. Additionally, this email provides users with both OpenPGP along with end-to-end encryption. 

One of these email providers’ most popular yet unique features is that they do not store the data on the hard drives since the server is diskless. Additionally, this service is headquartered in Sweden, a country under the jurisdiction of the 14 Eyes. 


Since Swedish authorities could potentially legally compel CounterMail to provide full access to its servers, it’s a good thing that users can delete their private keys from CounterMail’s servers and store them locally on their computers. CounterMail would not be on this list of the most secure email providers if this option were not available.

5. Tutanota

Tutanota is a secure email provider that is open-source and cloud-based. It is very easy to use and compatible with most devices. There are no ads as such and have end-to-end encryption as well.

The staff or the provider also does not have access to the messages, which is also termed the zero-knowledge platform. There are some limitations in the free version, which would generally be in terms of searching only one month’s worth of stored emails. 

The paid plans are slightly more affordable than most email providers. If you have opted for a personal plan, it comes up to $1 a month, whereas for business accounts, it’s $5. 

6. Runbox

Runbox is also considered a very secure email provider that protects the email and the user with the help of two-factor authentication and PGP encryption. They also provide a feature of both failed, and successful times someone has tried to log in to the account. 

To use this feature, you must allow Runbox to access your IP address. Another interesting thing about Runbox is that the servers are powered up with the help of hydroelectric power plants. 

Additionally, Runbox focuses on powering the servers only with renewable energy and is environmentally friendly. All their servers are based in Norway. It also has IMAP, SMTP, WAP, and POP support. 


Runbox, however, does not provide free plans to its users. They have various plans starting from $19 per year to $79 per year. The plans include Micro, mini, medium, and max. The email storage also depends on the plan; micro has email storage of 2GB along with file storage of 2GB.

Moreover, this email provider supports anonymous payments, and all the emails, including the subject, content, and recipients, are protected. They also had daily backups and secure storage with no logs and frequent deleting of logs. 

Some of the drawbacks of this email provider are that the custom domains are unauthorized, and there is no spam folder. All the spam emails are either directly sent to the regular inbox or are rejected straightaway.

Whether you are using the free version or the paid one, the data will be equally protected by the provider. Mailfence also allows you to certain custom features or the interface to meet the user’s needs. This is especially helpful when the user is in the business or paid plan. 

Apart from that, the paid version also provides more space for its users depending on the purpose of their usage. If they have to send out bulk emails or if the email is their usual mode of communication, certain settings can be changed, and it can also have more flexibility. 

One of the significant features of Mailfence is that it does not allow anyone to decrypt the messages, which is why it is considered to be one of the best private email providers. 

Some of the cons of this email provider are that they only offer 500MB storage for the free version, which is not as ideal for business purposes. Additionally, you must have a different email address to receive the activation key. 

Along with that, a source code is generally unavailable for any inspection, and the Mailfence servers also keep the private encryption keys. 

10. Librem Mail

Librem Mail is one of the best American email providers, which is very secure and provides encryption for all modes of communication. These would include video calling, voice calls, and chats aside from emails.

Since it does not track the users, it is also decentralized. This would also mean no ads and a proper VPN system that provides security. However, the drawbacks of this email provider are that the entire platform is only based on free software projects. 

This is also one of the main reasons users often face the problem of coming across several bugs and glitches, leading to the application crashing. 

11. KolabNow

Several secure email providers are Swiss-based companies. KolabNow is one of them, providing several features and additional security to its users. It provides 5GB storage to all its users, and all the data is protected under Swiss jurisdiction law.

This Swiss-based company also supports Perfect Forward Secrecy, which has a text search and powerful tagging feature. Some of the rules under which your data is protected are PCI-compliant, HIPPA, and GDPR. 

Additionally, the collaboration tools are very helpful while sending emails and customizing the control panel. The only downside to this email provider is that the debug report records are saved only when needed. 

12. Crip Text

Criptext is a free encrypted email service with open-source apps for Windows, Linux, macOS, Android, and iOS. However, the service is still in beta testing. Initially, this email service was built to be an extension of Gmail for encryption purposes.

crip text

Criptext is also considered one of the pioneers of the most secure email providers. The best feature is that there is no need for the recipient to have a Criptext account. Moreover, there are no paid versions, so that anyone can use this service for free.

The only downside to Criptext is that the server saves certain information. That information mainly includes the user’s details like recovery and primary email addresses, name, last active date, and the number of approved devices. Additionally, Criptext does not allow you to use the same on Outlook or Mail. 

Even though this email service does not offer additional storage for its users, the data is not shared with anyone. Even the staff cannot access the data, and the remaining stored information is secure. 

13. Disroot

Disroot is a secure email provider which is based in Amsterdam, Netherlands. The data is encrypted with SSL, which stays between the user and the email server. No other party can access it. 

Through the TLS protocol, the email provider’s server keeps all the data safe. However, one more thing that should be noted is that the recipient’s email server should also be able to support the encryption. 

Disroot also offers 2GB of free storage in the mailbox. In addition to that, they also support up to 10MB of documents through attachment. The user interface is also multi-lingual, making it easier for users to go about this email server. 

This email provider is available on different platforms and can be accessed by web page, IMAP, and POP3. Along with the email service, this provider also has other features, including chat, forums, social networks, and cloud storage. 

The only drawback of this email provider is that the storage space is limited. Even though it can be upgraded, it might be slightly more tedious for some users to pay for the extra storage. 

Disroot provides a comprehensive set of productivity and communication tools in the form of an Office-style web service. Unlike many of its competitors, Disroot is decentralized, open-source along with multiple federated services. 

Disroot’s email service is steadfastly private. The service has been in operation since 2015, though usage is difficult to track because the company does not keep track of the active users. 

14. FastMail

FastMail is an Australian private mail service, ad it has offices in the US as well. The provider encrypts every operation. This includes email sending and storage, account access, and more. 

FastMail is an email service that provides email accounts for businesses and individuals. Customers can use it in over 36 different languages. The company does not participate in any monitoring program hosted by the government.

Additionally, you can also select your Virtual Path Identifier. Along with that, the email address can also be customized. You can also easily search for the required email information without any delays. 

Since FastMail is a part of the jurisdiction of Australia, it comes under the Five Eyes surveillance agreement. This is an integral feature of FastMail as it not only has IMPA access but does not have any complicated or hidden policies. 

The user interface is also very simple and easy. The only drawback of this particular email provider is that there are no free plans available. 

15. Ctemplar

Ctemplar is yet another excellent private and secure email service. Its servers are physically located in Iceland. Iceland is also known for its strict privacy laws, which safeguard citizens’ privacy and freedom. 

The email service provides a free subscription for limited use. The free plan includes 200 emails a day, 10MB attachments, 10GB storage space, full encryption, and unlimited folders. 


Subscribe to their paid plans to increase or boost your limits. Ctemplar is currently only available by invitation. To obtain an invite code, you must either know a paying user and ask him for one or contact support and request one.  


Many free email providers either do not protect your privacy or actively work to undermine it. Switching to an encrypted email account is a worthwhile change. However, it is critical first to assess the provider’s encryption methods, means of financing the service, and server location. 

Each of the secure email services listed above is far superior to Outlook, Yahoo, Gmail, and others to keep your communications private. However, ProtonMail is the best service that deserves to be recommended. 

Of course, no online service is completely secure, regardless of the provider’s ethics. There will always be hackers and spy agencies looking to expand their ever-expanding databases. Some other email providers are based in Germany and Belgium, and Yahoo mail was also considered a very safe provider. However, other more secure email providers emerged as well.
