7 worst email providers for online privacy

The email providers listed below are on this list due to their lackluster approach toward data security and user privacy.

An email provider is expected to act as a vault for user data, ensuring that personal and professional communications remain confidential. However, these providers have shown, either through data breaches or privacy policy loopholes, that they are less than trustworthy when safeguarding user privacy.

Be it inadequate filters for spam emails, lack of end-to-end encryption, or questionable data handling policies, the following email providers have been found wanting in various aspects of data protection.

1. Gmail

Gmail, despite its widespread popularity, has been a topic of discussion among privacy advocates. Google's business model, heavily reliant on data mining for advertising purposes, poses a significant concern.

Prior to 2017, every email that landed in your inbox or was sent from your account was scanned for keywords to tailor advertisements to your profile. Although Google ceased scanning emails for ad personalization in 2017, the company’s overarching collection of data remains a concern.

One such concern is that using any tool from Google may result in the tech giant utilizing your data to train its algorithms and AI.

Moreover, Gmail's lack of end-to-end encryption (at least for non-Workspace users) leaves the content of emails susceptible to interception during transit. While Google has made strides in implementing strong security measures against external threats, the inherent design related to data collection and the absence of robust encryption cast a long shadow on the privacy of your Gmail account.

2. Microsoft Outlook

Microsoft Outlook, another heavyweight in the email service realm, has also been scrutinized for its privacy policies. The service has suffered from several notable data breaches, exposing sensitive personal data. One such breach in 2019 allowed hackers to access email metadata and folder names, although Microsoft claimed that the email content remained inaccessible.

Furthermore, up until recently, Outlook lacked end-to-end encryption, leaving emails vulnerable during transit. While Microsoft has a relatively better stance on data privacy compared to Google, the recurring security breaches and lack of robust encryption make Outlook a less-than-ideal choice for privacy-conscious users.

3. iCloud Mail

iCloud Mail, while sporting a clean and user-friendly interface, has its share of privacy and security concerns. Apple has been known to scan emails for prohibited content, which raises eyebrows regarding user privacy. Additionally, while iCloud Mail employs encryption, it's not end-to-end, implying that Apple holds the keys and can decrypt emails if required.

Moreover, there have been instances where Apple has shared data with law enforcement agencies, further questioning the level of privacy offered. While Apple portrays a strong commitment to user privacy in its marketing rhetoric, the actual practice surrounding iCloud Mail suggests room for improvement.

4. Yahoo! Mail

Yahoo! Mail has a blemished history regarding data security and privacy. The massive data breach of 2013, where every Yahoo account was affected, is a testament to the lax security measures in place. That's approximately three billion accounts compromised, making it one of the largest breaches in history.

Furthermore, Yahoo’s parent company, Verizon, has a history of using supercookies to track user behavior online for advertising purposes. Yahoo's turbulent past and Verizon's tracking practices make Yahoo! Mail a dubious choice for those prioritizing online privacy.

5. AOL Mail

AOL Mail, like Yahoo, is also under Verizon’s umbrella, and shares similar privacy concerns due to its parent company's data tracking practices for advertising purposes. Moreover, AOL has faced several significant data breaches over the years, which have exposed user emails and contact lists to hackers.

The lack of end-to-end encryption and a history of security lapses make AOL Mail a less trustworthy candidate for those seeking a secure and private email service. Despite its longevity in the email service space, AOL Mail has not kept pace with the privacy-centric features that have become paramount in today’s digital landscape.

6. Hotmail (Now Outlook)

Hotmail, now rebranded as Outlook, carries the same privacy concerns as Microsoft Outlook such as data breaches and a potential lack of strong encryption. Its transformation into the Outlook brand hasn't significantly altered the core privacy and security framework, leaving the same vulnerabilities intact.

7. Mozilla Thunderbird

Mozilla Thunderbird, unlike others on this list, is an email client rather than a standalone email service. However, its inclusion is warranted due to the privacy concerns surrounding its default settings. While Thunderbird supports encryption and privacy-centric add-ons, these features require a manual setup, which may be a hurdle for less tech-savvy individuals.

Moreover, Thunderbird's privacy is also contingent on the email service it is paired with, making it a bit of a wild card in the privacy discussion. Users must pair it with a secure email service and tweak the settings appropriately to ensure their online communication remains private and secure.

How can email providers invade your privacy?

Email is essential for both personal and professional communication. However, the convenience of free email services like Gmail or Yahoo! Mail often compromises user privacy.

The primary revenue model for these free email services is data collection and advertising. They analyze email content to tailor ads to individual users, thus intruding on users' privacy.

The absence of end-to-end encryption (E2EE) in many mainstream email services poses significant privacy concerns. Without E2EE, email providers can access and analyze email content, compromising user privacy and escalating the risk of data breaches, which can have severe consequences.

Data breaches, a harsh reality in the digital realm, expose personal information, affecting individual users and trust in digital communication channels. The intersection of data monetization, inadequate encryption, and potential data breaches underscores the importance of choosing a secure email provider to safeguard online privacy.

What to look for in a secure email provider

Choosing a secure email provider is a pivotal step in safeguarding your online privacy. It can help to ensure a spam-free and secure communication experience.

While the mainstream, free email providers often fall short in these aspects, there are several other providers specifically designed with privacy and security at their core. When contemplating switching to a more secure email provider, certain features act as hallmarks of a robust, privacy-centric service. Here's a brief rundown of essential features:

  • End-to-end encryption (E2EE): Ensure that the email provider offers end-to-end encryption to keep your emails private and secure from any prying eyes. This includes the email service provider.
  • Open-source: Search for open-source platforms, which are often more secure and transparent, thus, allowing for community code vetting for any security vulnerabilities.
  • No ads: Opt for a provider that doesn’t rely on advertising for revenue, which often involves scanning your emails to tailor ads to your profile.
  • Zero-knowledge architecture: Seek a provider that employs a zero-knowledge architecture, meaning they have no knowledge of your encryption keys and cannot access your data.
  • Strict privacy policy: Look for a strong privacy policy that clearly states the provider’s stance on data logging, sharing, and protection.
  • Two-factor authentication (2FA): Look for a provider offering two-factor authentication, which adds an extra layer of security to your email account.
  • Anonymous sign-up: You’ll want the ability to sign up anonymously, without providing personal information, which enhances privacy.
  • Custom domain support: While not a privacy feature, custom domain support can be valuable for professionals looking to maintain a branded email address.
  • Automatic spam filters: Look for robust spam filters to automatically move unwanted emails and potential phishing scams to your spam folder instead of your inbox.
  • Data servers located in privacy-friendly jurisdictions: Ensure that the email provider’s servers are located in countries with strong privacy laws.
  • Excellent customer support: Look for an email provider that offers multiple ways to get help, including self-help resources and methods of contact like email and phone.
  • Compatibility: Make sure your potential new email service offers apps for iOS and Android mobile devices as well as your browser of choice, such as Chrome.

These features collectively create a secure and private email environment, minimizing the risks associated with data breaches and unauthorized access.

3 more tips to secure your privacy online

Your email provider is just one facet of your online privacy. If you’re looking for more ways to keep companies from logging and selling your data, these tips are a great place to start.

    2. Update your privacy settings

    Most apps and browsers have security settings that you can adjust to your liking. Even if you’ve updated your settings in the past, it’s a good idea to regularly revisit them in case they’ve been reset or additional options have been added.

    3. Use a VPN

    A VPN (virtual private network) encrypts your data while you surf the web. This makes it more difficult for hackers to intercept your data and use it to infiltrate your device or steal your information.

    Additionally, VPNs hide your IP address so other entities, like your internet service provider (ISP), can’t track your online activity. The best VPNs balance security features with price, and these three offer the best value based on our testing:

    • NordVPN: A combo of a VPN, malware blocker, and ad blocker, NordVPN also offers additional security features that set it a notch above several other VPN apps.
