Most Secure Email Providers 2025:
https://signalvaultprivacy.com/secure-email/best-secure-email-providers-2025/"ProtonMail ($4.99/mo) wins privacy, Fastmail ($3/mo) wins features.""... if you use a regular email provider (Gmail, Yahoo, etc.), your emails could be scanned for ad targeting or handed over if requested. Privacy-focused email providers put security and encryption first, ensuring that even the provider can't read your mails."
"
Transport-level encryption is powered by TLS – SSL's successor- to encrypt emails during transit. Yes, this is the same TLS you frequently encounter while browsing websites.
In the case of emails, TLS applies on top of TCP (Transmission Control Protocol) to protect SMTP (sending email to server) and IMAP (retrieving email from the server) protocols. That's how it protects messages from the sender to the receiving end, given that the server at both ends supports encrypted communication.
Transport-level encryption basically secures your plaintext emails from hackers and snoopers.
...
In the case of
transport-level encryption, the email provider's servers control the transmission of secure messages. The servers can store and even read your emails; hence, anyone intercepting or hacking the server can access your messages."
"
End-to-end encryption - in the case of high-level encryption, th
e encryption begins right at the user's device – the endpoint. It remains encrypted during the entire transmission to the receiving end (the recipient's device), with no chance for the server to intercept or read the email. Also, the servers (and the service provider) cannot decrypt your message since the decryption keys only remain private to the sources.
Some common end-to-end encryption protocols include the following.
S/MIME: The
Secure/Multipurpose Internet Mail Extensions (S/MIME) is an asymmetric end-to-end encryption protocol that
works by verifying senders' identity via signed certificates from a Certificate Authority.
PGP:
Pretty Good Privacy (PGP) is a safer decentralized encryption system that utilizes symmetric and asymmetric protocols.
It's easy to use the services as it doesn't require the parties to exchange private keys. However, users must rely on third-party services (such as privacy-friendly email clients) for encryption."

Hushmail Review 2026: Secure But not a Privacy-friendly Option:
https://privacysavvy.com/reviews/email/hushmail/"Pricing: $11.99/month (Starter plan) - $49.98/year and $119 for 3 years with a 60-day money-back guarantee."
"Hushmail is a Canadian-based email service that has been in the industry for more than twenty years. It uses standard encryption algorithms such as TLA/SSL and OpenPGP to secure email messages."
"The company guarantees the protection of your email messages. However, the privacy policy complies with warrants requesting user data from the US and Canadian governments."
"Hushmail uses a secure SSL/TSL tunnel to encrypt your mail in transit, and OpenPGP encrypts it at rest. In addition to encryption, the service employs other advanced security features like certificate pinning and forward secrecy. Also, it uses HTTP Strict Transport Security (HSTS) to protect you against Man-in-the-middle attacks."
"... when sending an email to a third-party email service, the email is not sent directly. First, it is sent to the Hushmail servers, and then Hushmail takes charge of the authentication process.
The recipients will then receive an email bearing a link. The link leads to Hushmail servers; they must set a password. Upon clicking the link and setting the password, users can decrypt the message sent. This means the message never leaves the Hushmail servers and is always protected by OpenPGP encryption, whether sent to Hushmail servers or an external email account."
