Gmail and Yahoo Mail have around 1.5 billion and 225 million active users, respectively. However, these platforms are not secure and don’t prioritize user privacy, driving businesses toward secure email providers like ProtonMail and Zoho Mail.
Free and unsecured email providers often mine data and may even sell it to marketing people to send you personalized advertising. So, if you are also planning to switch to better email providers, don’t forget to compare your options based on privacy features, storage space, PGP support, DMARC policy, encryption types used, and data center location.
To help you make an easy decision, we have picked 7 of the most secure email providers that cater to businesses and offer premium plans for all budgets.

- Tutanota
Tutanota is a secure email provider with end-to-end encryption and two-factor authentication. It prevents email-based menaces by using AES and RSA encryption instead of PGP, which adds an extra layer of security by combining symmetric and asymmetric keys. This open-source platform takes privacy seriously and deletes IP addresses and emails from the heading metadata.
In addition to having dedicated apps for Windows, macOS, iOS, and Android, it’s also available on the web. Its three downsides are- it’s a Germany-based app and the country is associated with the Fourteen Eyes alliance, which means it cooperates in intelligence sharing. The second downside is that it lacks support for PGP and IMAP. Thirdly, its extra extra storage is expensive.

End Note
We recommend you visit the official websites of these platforms to evaluate if their features, prices, and security capacity match your expectations. You should also check if they support the deployment of SPF, DKIM, and DMARC for email authentication.
You can also begin with the free versions of 2 or 3 of them to decide which aligns best with your needs and then proceed to buy their premium versions.
