Most Secure Email Providers for 2025

With the world going digital and seemingly ‘net-neutral’, privacy and security are becoming more important concerns than usability. From secure browsers to efficient antivirus programs, privacy-conscious tech enthusiasts now want email providers that promise to provide end-to-end email encryption. If you are ready to prioritize safety and privacy and switch from Gmail, here’s the much-needed list of the most secure email providers you should try in 2025.

List of The Most Secure Email Providers

Tutanota

Tutanota tops our list of secure email providers because it offers end-to-end encryption of emails and subject lines. It is based in Germany, a land that has strict data handling laws. It is created on open-source technology, thus security experts can scrutinize the code whenever they wish to. Plus, it claims to provide zero-knowledge emails, notifications, and calendar events, which means that only you, the meeting attendee, and the recipient can access the information in the email. Nobody else, be it the staff members, quality assurance engineers, or auditors, can decrypt the data exchanged via email or stored locally on the server. But what distinguishes Tutanota from ProtonMail (our second recommendation in the list)?

• Tutanota offe2-factortor Authentication, ProtonMail does not.
• Tutanota encrypts subject lines, ProtonMail does not.
• ProtonMail offers self-destructing emails, Tuanota does not.

The company delivers security in the email process and promises to ‘add’ usability features regularly. According to the official website, the developers have already started working on Post-Quantum Secure Encryption, and want to implement it ahead of government agencies that are planning to use the same technology to decrypt emails. The company offers apps for all major platforms: Android, iOS, Desktop, and web versions. Tutanota has two different price bands, known as private and business. The basic plan in ‘private’ is a free offering of 1 GB storage. An upgrade is only €1.20/month. Business accounts with Tutanota are not free.

Protonmail

Protonmail seconds in our secure email providers list thanks to its end-to-end email encryption and self-destructing emails. Its server is based in Switzerland. The email lookup tool claims to utilize the most advanced encryption standards with which not even the in-house staff can decrypt. The company does not log IP, which means ProtonMail does not have any part of your digital identity or footprints.

The platform is based on open-source technology, created by scientists and developers who have a mission to protect public liberty. Users can further set expiration dates for outgoing emails. The feature destroys the email and deletes it from the recipient’s mailbox right on the date set by the sender. Users don’t have to provide sensitive information while signing up, but they are required to follow an SMS verification process. When handling an email list, be aware of these privacy limitations to ensure your communication strategies remain secure and effective.

Protonmail’s basic email account is free, which, of course, has a limit on storage space (500 MB) and only 150 emails per day with no custom domain. The premium plans of ProtonMail start from as low as €4/month, but there are different tier bands: plus, professional, and visionary.

Mailbox.org

Mailbox.org, based in Germany, is a private email service provider that does not ask for your data during the sign-up process. You will only be asked to provide a phone number or recovery email address in case you have forgotten the password. It offers great security features: you can set filters that will notify you before sending an email to a recipient who does not use a secure email platform. You can also choose to send normal or encrypted emails, which can be considered a blessing or an email nightmare, depending on the content of your email. The email provider keeps updating the platform for security, and the developers are planning to deliver more benefits.

When you sign up, you also get access to cloud storage space and a text editor, while the quality and quantity of these services do depend on your package. Mailbox.org, more suitable for professionals and business users, does not have a free plan, and the basic plan starts from €1 1/month, offering 100 MB cloud storage and 2GB email storage.

Zoho Mail

Zoho has data centers all around the world, and the website does show a map with top locations being Ireland, the  Netherlands, the USA, China, and Australia. It also offers end-to-end encryption for all the data in email, whether they are resting in the cloud storage space or is in transit to other recipients. Zoho has a method to notify about the security and encryption levels of incoming emails; in case the email is coming from a not-so-secure platform, Zoho will mark it as Plain. It also promises to protect user privacy and has strict codes of data handling, whereby only the sender and the intended receiver can decrypt and read the email; nobody else on the server or in the loop can do so. Their privacy and security vision can be trusted, considering the compliance certificates available on their official website.

The starting plan, called Mail Lite, is worth $1/month, offering 5GB storage space. Users can enjoy multiple domains with a single account and use other email clients of their choice, with the emails still secure with IMAP/POP protocols. All plans have calendars and bookmark options. Zoho Mail also has apps for Android and iOS devices.

Canary Mail

Canary Mail is an email client app that is designed to enhance email security and protect user privacy. The foundation of Canary Mail’s security lies in its support for PGP encryption and secure send. This ensures that users can communicate confidently, knowing that their emails are encrypted, granting access only to the intended recipients. Acknowledging the vulnerabilities associated with passwords, Canary Mail introduces an additional layer of security through Two-Factor Authentication (2FA). Even if passwords are compromised, unauthorized access remains a significant challenge. In a bid to fortify user privacy, Canary Mail goes a step further by blocking read receipts. This deliberate measure not only shields users from intrusive tracking but also serves as an effective privacy-enhancing feature.

Putting users in control, Canary Mail allows for the customisation of encryption key management. This feature empowers users to dictate and manage access to their encrypted communications, adding a nuanced layer of security. Recognising the importance of device-level security, Canary Mail provides options for biometric authentication (Touch ID/Face ID) and passcode protection. These measures act as robust gatekeepers, ensuring that only authorised users can access the email app. Canary Mail proactively safeguards user privacy by defaulting to block remote images, thwarting potential IP address tracking by email senders, and bolstering overall online privacy. Attachments and data stored within the Canary Mail app benefit from secure cloud storage protocols. This added layer of protection reinforces the security of user files against potential threats.

Canary offers a free version with the option to upgrade to the premium version for an affordable yearly fee of $20. By upgrading, users can access additional functionalities and features that enhance their experience with the app.

Privatemail

Privatemail offers end-to-end 256-bit email encryption and secure cloud storage space with all of its plans. It is a mid-level secure email provider more suitable for professionals who are ready to trade off some level of safety against an efficient email calendar and highly secure file sharing. Privatemail also offers a self-destructing email option and strong synchronization between the email platform and device. The email provider has developed a dedicated desktop version along with apps for Android and iOS devices. It’s basic, also the bestseller plan is worth $8.95/month, offering 100GB each for cloud and email storage.

Its main server is located in the USA, which means you can expect the top-notch quality of services and high-speed email deliveries. Being located in the USA does make its privacy promise somewhat questionable, if not entirely objectionable. ISPs and certain tech companies are legally bound to log user activity. Privatemail, however, has never been part of any such scandals and has never been caught processing or selling users’ data. Therefore, keeping in view its high encryption standards, performance history, and usability features, it is still a good choice (in fact, better than other privately funded email services) for those who prefer security over privacy and pricing.

Atomic Mail

Atomic Mail earns its place among the most secure email providers with true zero-access encryption and a privacy-first approach. Based in Estonia, it encrypts all emails client-side, ensuring that not even Atomic Mail can read your messages. Unlike traditional services, users can sign up anonymously without providing a phone number or personal details, making it easy to send anonymous emails and strengthen privacy from the start.
The platform also supports the creation of multiple free email aliases, making it easier to separate communication channels and protect your main identity. For account recovery, Atomic Mail uses a cryptographic seed phrase instead of phone numbers or insecure backup emails, adding an extra layer of protection. Importantly, there is no tracking, advertising, or data mining across the platform.
Key features include:

• End-to-end encryption and zero access to user emails.
• Anonymous sign-up and free alias creation for enhanced privacy.
• Ability to send anonymous emails without linking personal information.
• Secure account recovery with seed phrases (BIP39 standard).
• No data tracking, no targeted ads, and no profiling.
• Encrypted communication security across devices.

Atomic Mail offers a clean and intuitive web experience and is currently expanding to mobile, making encrypted communication accessible wherever you are.

How to choose secure email providers?

Consider these security and privacy factors before choosing an email client:

1. End-to-end encryption: not all email service providers offer 256-bit encryption. Make a decision based on their security certificates, level of security, and parts of your emails they are willing to encrypt.
2. Location of the datacenter: Check where the email provider’s server is located. Give a plus point to clients that are based in jurisdictions outside Five Eyes. Such countries have strict regulations about data handling.
3. Advertisements: an email service provider that allows advertisements on the platform can’t offer 100% security. It is processing your private information and selling it to third parties who then send personalized marketing campaigns your way!
4. Secure file sharing: users share attachments in emails. If an email service claims to provide safe file-sharing, you can surely give it a try.
5. Information collection and handling: Read the privacy policy to understand what information the email service collects during the signup process. Also, check how the provider handles your data.
6. Open-source technology: the email platform should be created with open-source code, allowing security auditors and privacy advocates to examine the level of security.
7. Self-destructing emails: It is a rare feature that removes an email after its predetermined expiry date. Only 2-3 email providers tend to offer this feature, so it is not advisable to base your buying decision completely on this feature.

Is email security enough?

Email Security should be prioritized when choosing an email service provider. However, we recommend our audience consider these factors too to make an informed decision:

• Compatibility with major platforms: desktop, Android, iOS, web browsers
• Email and cloud storage space
• Minimum and maximum attachment sizes
• Calendars, encrypted ones are better.
• Email organization: spam and search filters

Our recommendations and reviews are based on all the aforementioned factors, security features being fundamental.

Based on critical analysis, detailed examination, and continual testing, we nominate Tutanota as the best and most secure email provider for 2025. Our recommendation is based on all the security factors mentioned previous sections of the article, including the pricing plans, adherence to the privacy mission, and their plans to strengthen user privacy and security. Tutanota is the best alternative to Gmail as it does not contain ads and promises not to collect, log, or use private data. It guarantees never to participate in ad programs to channel third-party marketing.

Is a secure email provider enough for a safe internet experience?

While email service providers and browsers are paramount to digital security, users need tools for added privacy and online freedom. Your emails can be anonymous, but what about your overall online presence and your digital fingerprint? To ensure an overall safe internet experience in 2025, digital experts recommend users create a customized suite for themselves comprising a secure email service, a trusted VPN, a proactive antivirus program, an efficient device finder, and a secure browser.

How can iProVPN and Secure Email Provider Tutanota help you achieve maximum online security?

While Tutanota can encrypt your email communication and protect your confidential data with 2-factor Authentication, iProVPN can mask your IP address to ensure network-level security. Similar to Tutanota, it is based in a safe jurisdiction, the British Virgin Islands, and companies don’t need to log activities.

iProVPN provides an ideally secure environment, does not log user activity, and hides online behavior. It prevents third parties and cyber attackers from creating users’ digital fingerprints. It offers 256-bit AES encryption, the highest industry standard for security. Read our privacy policy to gain a better understanding of the transparency of services.

Are you ready to take the plunge and regain your online freedom and anonymity? Remember that these are your basic digital rights. The Internet is super functional because of you: only you should have the right to access your sensitive information. Take your first step to internet security and play your part in making the internet safer for everyone.
