A secure email provider offers extra layers of protection to keep your emails safe from prying eyes. Unlike standard email services, secure providers use end-to-end encryption to ensure that only the intended recipient can read your emails. This means your email stays encrypted from the moment it leaves your device until it reaches the recipient’s inbox, keeping it safe from any unauthorized access along the way. Now, while terms like “secure” are used frequently, there’s no one-size-fits-all definition of a secure email provider. Any company can claim to offer secure services. That’s why it’s essential to evaluate the kind of encryption they use and the overall security measures they implement.

What Happens When You Use a Regular Email Provider?  

Services like Gmail do offer some level of encryption. When you send an email, they use Transport Layer Security (TLS) to protect it while it travels between your device and the Gmail server. However, once your email arrives at the server, it can be accessed by the provider. While Google has stopped reading emails for ad targeting since 2017, it still scans email content to offer features like Smart Reply. This means that the company—and potentially third parties—can access your emails. Your email may be encrypted while in transit if the recipient’s provider also uses TLS. But here’s the catch: if their provider doesn’t, your email is exposed and can easily be intercepted. Moreover, even if it’s protected during transit, it might not stay secure once it lands on the recipient’s email server, as not all providers encrypt stored emails.

How Do Secure Email Providers Work?  

End-to-end encryption is the gold standard for protecting your emails. With this, even the email provider can’t access your messages—only the intended recipient, who has the right authentication, can decrypt and read them. Some providers also implement additional measures like Sender Policy Framework (SPF). SPF helps verify the authenticity of the emails sent from your address. So, if someone attempts to send an email from an unauthorized IP, the receiver will be alerted that the message is from an unverified sender.

Do You Need a New Email Address with a Secure Email Provider?  

In most cases, switching to a secure email provider means creating a new email address. You can forward emails from your old account, but bear in mind that these forwarded emails will still pass through your old provider’s servers, so they won’t be fully encrypted. Some secure providers offer features that make transitioning smoother, helping you migrate emails and contacts from your old provider. Choosing a secure email provider is essential in safeguarding your personal information, keeping your emails safe from prying eyes, and maintaining your privacy in an increasingly interconnected world. 

Best 5 Secure Email Providers

• ProtonMail
  ProtonMail is one of the most popular choices for secure email services. It’s an open-source platform headquartered in Switzerland, offering end-to-end asymmetric encryption to protect your communications. ProtonMail has a free tier, ideal if you’re sending fewer than 150 emails a day and don’t require a large amount of storage. One standout feature of ProtonMail is its ability to send self-destructing emails. You can set an expiration date for the email, ensuring it’s automatically deleted from the recipient’s inbox after a certain period.

ProtonMail uses zero-access encryption to store your data, which means that even the service itself cannot access or decrypt your emails, nor can it recover your password if lost. Additionally, ProtonMail offers apps for both Android and iOS, making secure communication easy on the go.

•  Mailbox.org
  Mailbox.org is a secure email service tailored for business users who want an alternative to Google or Microsoft. Along with email, it provides encrypted cloud storage, video conferencing, a calendar, an address book, and a task management tool.

It uses PGP encryption, a widely recognized standard for securing email communications. While there’s no free plan, Mailbox.org is quite affordable, and users can sign up and pay anonymously. Another key feature is its commitment to eco-friendly energy, ensuring that the platform is powered sustainably.
