Hushmail, as the name suggests, is an email encryption service that secures messages and ensures email conversations remain confidential and safe. The primary function of Hushmail is to protect client communications by encrypting messages, web forms, and e-signatures.
Hushmail is easy to use as all that users have to do is sign up on the official website and provide an email. The user interface is clean enough but lacks some modern features such as a multi-panel message pane, and a drag/drog message function.
In terms of privacy, Hushmail is an average email encryption service as the service is located in Canada and is a subsidiary of a US firm. Hushmail also requires users to agree to some processing of data. Apart from that, Hushmail informs the user of potential collaboration with law enforcement agencies in certain situations and does not have a transparency report. Hushmail is reasonably reliable as it is designed for healthcare professionals and is HIPAA compliant. Hushmail is lacking in terms of privacy though as the service operates outside Canada and encrypts messages on company servers rather than the user’s machine.
To use Hushmail, users only have to go to the official website and provide an email address and/or phone number to sign up. Once completed, the main interface provides two prominent buttons labeled ‘Check Mail’ and ‘Compose’, both of which users can instantly start using to send/receive encrypted email.
The main advantages of Hushmail include features for private (encrypted) message exchange even with non-Hushmail recipients and HIPAA compliance. Disadvantages of Hushmail are the lack of dedicated apps for platforms like Android, collection of personal data, and the requirement to provide personal data to sign up.
Hushmail has numerous subscription packages for different types of users. The primary target audience is healthcare. Hushmail for Healthcare professionals comes with a Starter subscription package which costs $9.99 per month ($109 annually), a Recommended package that costs $19.99 per month ($219 annually), and a Custom package that costs $39.99 per month ($439 for those who pay annually).

Paid features of CounterMail include an XMPP chat server, auto-responder, message filter, email notification, secure forms, a USB key option, and a custom domain name. Other paid features include increased storage space and custom domain including USB credits. Apart from that, full disk encryption, PGP-encrypted unencrypted email, SSL-MiTM protection, and a password manager.
CounterMail is reasonably easy to use as users only have to go to the official website, sign up and use the webmail interface with a pre-generated PGP key. CounterMail also makes importing contacts easy with two or three clicks and does not require the user to have the key for recipients using Countermail or Hushmail users as the service can fetch those keys automatically. The user interface is considered unattractive by some users though.
As far as privacy is concerned, CounterMail is reasonably private. But the service is based in Sweden, which has many data retention laws. Sweden is also a member of the 14-Eyes agreement which states that law enforcement agencies can extract data from any service. Countermail does, however, use end-to-end encryption which is great for privacy and doesn’t store user encryption keys.
CounterMail is reliable as the company takes several steps to make sure user data remains out of the reach of even CounterMail staff. The official website does not use any cookies which is also a positive sign of reliability. To use CounterMail users have to go to the official website, sign up for a package, use the web interface, or a free mobile client to set up CounterMail.
Advantages of CounterMail include cryptocurrency payments, SSL AES-CBC and RSA encryption, and secure servers. Disadvantages of CounterMail include expensive packages, old UI, average website design, and lack of dedicated mobile apps.
CounterMail offers three different subscription packages. The 6-month package costs $29 (which comes down to $4.83 per month) while the 12-month package costs $49 (or $4 per month). The third package is called the 12×2 package which costs $79 (or $3.29 per month).
At the time of writing, CounterMail had no discount options and/or sale campaigns. CounterMail does offer more plans for users who want extra space. The price for each upgrade can be anywhere from $19 to $89. Users who want to take advantage of the Domain option have to pay $15 as a one-time setup fee.
Currently, CounterMail does not offer a free version. The service does have a free trial though which expires after 10 days of sign-up and grants access to everything on the premium account. Another requirement to use the free trial feature is that the user must know another user who is using Hushmail and get an invite code from the other Hushmail user.
CounterMail does not have a traditional money-back guarantee but the service does allow users to ask for a full refund within 14 days of paying for a given CounterMail product. However, users who have sent an email via a CounterMail account cannot claim a refund for that account.
Runbox is another email encryption service provider that claims to connect users via secure and encrypted email communication. The main functions of Runbox include encrypting email messages, implementing strong authentication procedures, and keeping operations environmentally friendly.
Runbox is average in terms of usability as the UI is not modern. However, Runbox is still very functional and follows the tried-and-tested interface of a two-column view.
In terms of privacy, Runbox is slightly below average since the service does not offer end-to-end encryption and doesn’t encrypt the entire inbox. Even using PGP requires the user to set things up manually. The service does comply with strong privacy laws in Norway though. Runbox is not as reliable as some of the other options mentioned here as the service does not have dedicated apps which decreases opportunities for access. There are no desktop apps either. Runbox is not open source and the system does not encrypt data within it while at rest.
To use Runbox users have to sign up for a package via the official website, provide an email address and sign in via the web interface. From the interface, clicking the Compose button should allow users to send messages with TLS/SSL encryption.
Advantages of Runbox include multiple payment methods, custom domains, email aliases, GDPR compliance, synchronization abilities, IMAP/POP/SMTP support, environmentally-friendly policies, and hidden IP addresses. Disadvantages of Runbox are a lack of mobile apps, lack of desktop apps, lack of strong encryption, lack of bonus features, and the fact that the service is closed source.
Runbox offers several different subscription plans based on the needs of the user and the upgrades required. But the four standard subscription packages are Micro (which costs $19.95 per year), Mini ($34.95), Medium ($49.95), and Max ($79.95). Each account offers access to the same features. The real difference is the amount of email storage space and file storage space along with email hosting domains that a user has access to.
Apart from the above primary accounts, Runbox also offers sub-accounts of the major accounts mentioned above. The sub-accounts also have four subscription packages labeled Micro (which costs $7.95 annually), Mini ($14.95), Medium ($24.95), and Max ($39.95).
Runbox also offers email and web hosting upgrades which can further increase the price the user has to pay on a yearly basis. Runbox does not offer monthly packages.
Runbox does not offer a free version of the company’s main email encryption service. However, Runbox does offer a 30-day free trial with every subscription package. Users are free to not use the free trial option and pay for a subscription upfront in which case Runbox will add the 1 month in the annual subscription period.
As far as a money-back guarantee is concerned, Runbox offers a whopping 60-day refund policy which allows users to experience the service and then make a final decision.
12. Barracuda Email Encryption Service
Barracuda Email Security is an email encryption platform/gateway that promotes a secure and private email messaging experience via strong encryption implementation and compliance with tough privacy requirements. The main function of Barracuda Email Security is to encrypt user data both at rest and in motion and comply with various data privacy laws to ensure not only security but also privacy.
Barracuda Email service is not easy to use as users have to fill out a form to get a free evaluation unit which takes an unspecified amount of time. The service also does not have dedicated apps and very few integrations. The main web interface is cumbersome and not streamlined.
In terms of privacy, the Barracuda email service is top-notch since the service complies with PII, GDPR, HIPAA, and PCI among other privacy laws. Barracuda makes use of strong encryption to protect email and related attachments. Barracuda email encryption service is also very reliable since the company behind the service is trustworthy and has decades’ worth of experience in providing business-class email security solutions. There are no dedicated apps though which may lower the reliability score.
To use Barracuda, go to the official website, fill up the request form, purchase a license, log in via the Barracuda Email Security Gateway and then configure encryption policies. To activate encrypted mail archiving users will have to go to the Administration page and go through the entire process either alone or via customer support.
Advantages of Barracuda include a trustworthy brand, corporate-level encryption services, lots of customization options, and expert customer support. Disadvantages of the Barracuda email service include a cumbersome sign-up and configuration process, excessive configuration options, and a lack of standard subscription plans.
To obtain pricing information, users can go to the official website of Barracuda and schedule a demo or use the live chat feature to obtain a quote. As previously mentioned, Barracuda email encryption service offers some very advanced features and more often than not, the type of client coming to Barracuda will have very specific needs.
Generally speaking though, clients should expect to pay a minimum of $2.63 per month per user and based on the additional security features required, the price will definitely go up.
At the time of writing Barracuda email encryption service did not offer any discounts or had any sale on available packages (part of the reason may be that Barracuda doesn’t mention subscription package prices up front and instead asks the interested party to get a quote).
Barracuda email encryption service does have a free version and may even have a free trial depending on the type of client and how the negotiations go with Barracuda staff. Currently, Barracuda does not have an officially set money-back guarantee policy.
What are the Types of Email Encryption?
The types of email encryption include PGP/MIME and S/MIME, among many others. PGP email encryption is short for Pretty Good Privacy email encryption and was developed by Phil Zimmerman in 1991. Now PGP is used in the vast majority of good email encryption services. PGP involves encrypting data with a random key and then the same random key getting encrypted with the receiver’s public key. Upon receiving the encrypted message, the receiver may use the private key to unlock the encrypted message and the random key. PGP works on a decentralized model. The main difference between PGP and S/MIME is that S/MIME works on a centralized model in which the user must obtain the encryption key from a specific certification authority (CA).
Another type of encryption is the GNU Privacy Guard which makes use of a symmetric key and public key. In this type of encryption, asymmetric key pairs are generated first and the sender and receiver of the message receive the pair for encryption and decryption. Another type of email encryption is Bitmessage, which is more suited to individual users and relies on peer-to-peer authentication. STARTTLS is another encryption type that provides encryption for messages while in transit. While safe, STARTTLS opens doors to MiTM attacks. Another email encryption type is MTA-STS or DANE which is pretty similar to PGP/S-MIME and STARTTLS. In fact, DANE (and MTA-STS) overcomes some of the shortcomings of STARTTLS. DANE forces the recipient and the sender to use TLS and blocks attempts at stripping away TLS. MTA-STS makes use of CA and TOFU, while DANE uses DNSSEC.
How do Email Services Encrypt your Mails?
Encryption is the name of the process that services use to convert legible data into gibberish using a secret format. According to the encryption definition, only the receiver having access to the secret format may turn the gibberish data back into its original state. More specifically, plain text is first converted into ciphertext and then sent as scrambled data. The receiver must use a password or a key to convert the ciphertext into plain text and read the message. Encryption is very important in modern communications to protect sensitive data and conversations from hackers and other snoopers.
Note:Most email services use TLS for email encryption. The user’s web browser contact’s the email service provider’s servers in order to secure and establish a connection. Then the email service encrypts the user’s message, passes the message through the servers, and then to the final destination.
On a more granular level, most email services use PKI to encrypt and decrypt messages. In the PKI arrangement, the sender and receiver get a public and private key. A key server stores the public key with the related user information. Once uploaded to a given email service’s servers, the email service uses the public key to encrypt the email. The sender has to provide the receiver’s public key to encrypt a given message. Then a given email service uses the private key of the receiver to decrypt the message.
Isn’t My Email Already Encrypted?
Yes, but only for mainstream email service providers like Gmail. Even Gmail only uses TLS for email security which only provides encryption in transit. Gmail also provides paying customers S/MIME. The gap remains the same though. Even though email is encrypted when in transit, once the email message reaches the inbox of the receiver, there is no encryption to protect the message.
To check if a given outgoing email message is encrypted when composing a message via an email service like Gmail, take a look at the recipient’s field. On the right-hand side of the recipient’s field, there should be a lock icon. The lock icon indicates the level of encryption. If the recipient of the message supports enhanced encryption, the message will be encrypted.
To check if the message received has encryption, the user should open a message (assuming the email service provider is Gmail), and then (on iOS or Android) click on the option that says ‘View Details’. After that, click on ‘View Security Details’. From there, the user should look for a colored lock icon. A green lock icon will indicate S/MIME encryption and a gray icon will indicate TLS encryption. A red lock icon will mean the message is unencrypted.
Which Email Services can be Encrypted?
Almost all major email services can be encrypted based on the subscription package of the user. The email services that can be encrypted are given below:
- Gmail (only for users with access to G Suite email encryption): Gmail users automatically get access to TLS encryption. That is why, generally speaking, Gmail is fairly secure. G Suite Enterprise users get access to S/MIME encryption as well. To enable S/MIME in Gmail, users first have to go to the Google Admin console and then click on Apps. After that users should click on G Suite and then on Gmail and then go to User Settings. From there, choose the organization or the domain for configuration and click the option that says Enable S/MIME for both receiving and sending emails. Then click the button that is labeled Save.
- Outlook (via Office 365 Enterprise E3 license): Similar to Gmail, Outlook does make use of TLS encryption to protect all messages. As mentioned before, TLS is only good when the messages are in transit. To counter this problem, Microsoft implements a separate email encryption system for Office 265 Personal and Office 365 Home subscribers. This makes Outlook a secure email service.
To start sending email messages that are encrypted via Outlook, users first need to go to the official website of Outlook and then sign in. After that, users should click the New Message button (based on the theme used, this button could be blue) which is located in the top-left section of the screen. There should be an encrypted option shown via the ribbon. Users need to click the Encrypt option (sometimes this option may be labeled as ‘Encrypt & Prevent Forwarding’). After that users should input the recipient’s address, the subject line, and any content that should go into the body of the email message and then click on the button labeled Send.
- Yahoo Mail: After Gmail and Microsoft, Yahoo is probably the third-most used email service provider. And similar to both Microsoft and Gmail, all users get to use TLS encryption on all email messages. To enhance encryption and take advantage of all the benefits that come with end-to-end encryption, users need a third-party plug-in to use with Yahoo Mail. The plug-in needed is Mailvelope. Once installed on Chrome or Firefox, Yahoo mail users need to configure Mailvelope correctly. After that, users need to go to compose a new message in Yahoo Mail. If Mailvelope is installed correctly, the plug-in will show a Mailvelope symbol in the top-right area of the screen. Users need to click the option that says Encrypt after filling out the details of the message (recipient’s address, content of the body, and subject line) and then click ‘Send’.
Do I Have to Pay for Email Encryption?
No, online users do not have to pay for email encryption. Of course, users can pay for email encryption if more advanced security features are needed and there is a desire to support email service providers offering complete encryption for email communications. Some of the most well-known free email encryption services include Virtru and PreVeil, both of which offer top-of-the-line encryption for free. Similarly, SecureMyEmail becomes free if users restrict usage to a single Microsoft/Yahoo/Gmail account. There is even a 30-day free trial period.
Perhaps the two best and most user-friendly free email encryption services are Tutanota and ProtonMail in the sense that users can get set up in a matter of minutes. Both are excellent services but come with a few limitations. While Tutanota does not have an official limit on the number of messages the user can send, the company does block users from sending messages if the user activity matches certain patterns. Tutanota Premium increases the number of messages the user can send before the service steps in and stops the user for a limited time from sending more.
There is also ProtonMail which is completely free and very secure. ProtonMail has similar restrictions to Tutanota but does offer a cleaner and more convenient user interface.
Lots of other email encryption services mentioned in the list mentioned above do not have any kind of limitations but users do have to pay for the privilege.
What could Happen if a Hacker Took over My Email?
Lots of different forms of harm can take place if hackers take over email accounts. If a hacker took control of an email account, according to the hacking definition, the user would be at risk of information loss or malware installation. For example, if a hacker takes over a given user’s email account, the hacker is free to send as many emails to contacts and non-contacts as desired for as long as desired from the user’s hacked account. This is a big enough problem in itself but hackers can go one step further and try to scam the user’s contacts for money and information. Not just that, hackers can infect email messages with malware and then send such messages to hundreds of other users.
Hackers can compromise the online identities of people whose accounts have been compromised. Hackers can also hack the compromised account’s employer, potentially landing the user in further trouble. Potentially, a single hacked account can run the professional life of the victim within days.
Apart from that, cybercriminals can use compromised email accounts to blast out phishing emails to even more users and steal the personal information of every user that falls for the phishing email scam and inputs sensitive information into a legitimate-looking fake website.
Many online users use email addresses not just for receiving emails, but also to sign up for hundreds of other services and, in some cases, for identification services. So a compromised account can lead the hacker involved to access not just the user’s email messages and contacts but also social media profiles, Google Drive content, and any other account that the user has linked the email address to.
If the email account that gets compromised is a primary one, hackers can use the account to send ‘forgot password’ requests to many other accounts and change the password of those accounts as well. So one primary email address account can lead to lots of other accounts being hacked as well.
Perhaps the most obvious danger of a hacker taking over an email account is access to personal information. Hackers can use any piece of information to, for example, compromise the victim’s Facebook account and get information about the victim’s family, friends, co-workers, and colleagues. Every small detail of the victim’s life is at risk when hackers take over an email account.
There is nothing stopping hackers from also stealing financial information. Stolen financial information can lead to monetary losses for the victim in question. Hackers often use the compromised email address to find the victim’s debit card information and then use that to contact the concerned bank to either withdraw money or change financial details. Hackers may also know all the transactions the victim has made in a given year. With enough financial information in hand, hackers can open new bank accounts in the victim’s name and apply for loans wherever possible, which in the long term can hurt the victim’s credit score.
Finally, hackers can use the information found within the hacked email address to blackmail the victim and spy on the victim by never disclosing to anyone that the email account has been hijacked and hence spying on any new incoming email messages. Such information can also be used for extortion.
With the information contained in the email account itself and the secondary information available with all the connected services, hackers can get all the personally identifiable information that is needed to impersonate the victim and carry out even more harmful activities.
How do I Know that Someone Read my Private Emails?
There are services available that let the user know if someone has read the email sent to the recipient. Knowing if the recipient has read the sent message has to be understood in the context that the sender may want to know if there is a need for a follow-up email message. Or the sender may like to know if the message reached the inbox of the receiver. Sometimes, knowing if someone has read a sent private email can help the sender improve future email messages by working on the subject line and the actual contents of the email message. Of course, there are privacy issues to deal with as well (some recipients may not want to give up the information regarding whether or not the received email message was opened or not).
Note:The two main methods of knowing that someone has read a given private email message is to first enable the feature ‘read receipts’ which is available in most email services today. And the second method is to use a third-party email tracking plug-in.
Requesting a read receipt is by far the easiest way to know if a sent message has been received in the inbox and has been opened by the recipient. Some email service providers use the term return receipt instead of read receipt. Fortunately, both Gmail and Outlook offer the read receipt feature. In Gmail, free users cannot request a read receipt. A subscription to Google Workspace (or G Suite) is required. To enable the feature users have to go to the admin console and then to Apps and then to Google Workspace and from there enable Email Read Receipts in User Settings. Outlook offers a much simpler experience though and the feature is available to everyone.
There are many email tracking tools to see if someone has read a private email but MailTracker is considered a very good option.
Apart from requesting read receipts, delivery receipts, and email tracking tools, there are other methods as well. One such method involves the user inserting an image into an HTML email message to show if the email message was opened. The method of inserting images into email messages is considered more reliable than the previous methods just mentioned. The image inserted in the email address can be invisible. Moreover, the recipient does not need to know if the message contains an image to indicate whether or not the message has been opened and read.
Can Text Messages be Encrypted like Emails?
Yes, text messages can be encrypted like emails. There are many methods to encrypt text messages just like emails. The most convenient way to send encrypted text messages is to simply switch to a messaging service that uses end-to-end encryption by default. There are many messaging apps out there that encrypt text messages by default. One of the best encrypted messaging apps is WhatsApp. Signal and Telegram are also good options if other contacts are willing to switch as well.
If switching to a different messaging service is too cumbersome, users can also sign up for a third-party tool that can encrypt messages. Such services can be used to encrypt messages and then send the messages to the intended recipients. One of the apps that will encrypt text messages for the user is ‘Encrypt Messages and Text’. This app is for users who want to send messages via text or SMS rather than a messaging app via WiFi. Generally speaking, both the receiver and sender of the message need to have the app mentioned above. Then, the two parties also need to agree on a password to decrypt the encrypted SMS message. Using the app, users can encrypt the message to be sent. Upon receiving the ciphertext via SMS, the receiver can copy-paste the text message into the app and use the password to decrypt the ciphertext.
For iOS users, the process is even simpler since iOS offers the iMessage app which offers end-to-end encryption. The iMessage app can read the Apple ID and use that with iCloud to provide end-to-end encryption to users of the iMessage app. In fact, the iMessage app is unique in that the app encrypts both sent and received messages and attachments.
Android users have to make use of third-party applications (as mentioned before), the most recommended app for such a situation is Signal. Signal is available for all platforms including iOS, Windows, Linux, macOS, and Android. Users can install the relevant app from the official website (in turn either via Google Play Store, the App Store, or the Windows Store) and send messages to other users making use of the same app. The Signal app can also encrypt files, videos, audio messages, and voice notes. Signal is one of the few apps on the Android platform that offers end-to-end encryption. Best of all, Signal is open source.
A lesser-known but equally competent encrypted messaging service is Threema. Threema is different from other messaging services because the app puts privacy and security over everything else. Threema is not free though. Users have to pay a one-time fee to use the app. The official Threema app does not collect any user data and is completely open-source. Not only that, the Threema app is GDPR compliant, does not show any ads, offers end-to-end encryption, and does not require a phone number to register and use.
