The 8 Best Secure Email Providers [2024] | Spike (2024)

The more connected our world becomes, the more critical it has become to protect your personal information and privacy. Unfortunately, because email isn’t tied to one particular company, it’s often difficult to understand how to implement a secure online email provider.

At Spike, we believe that email should be private. Spike is ad-free and does not rent, sell, distribute, or monetize your data. We store only the minimum data needed to provide the fastest communication and collaboration experience. When using Spike, all message data is encrypted using AES-256 encryption.

The problem for consumers and business customers is that even if your email client isn’t mining your data, do you know what your email provider is doing? For example, some providers mine your data to serve you more personalized advertising. Some might say that ads are part of using a free email service, but we disagree.

Tutanota is completely open-source and runs on renewable energy. One of its most unique features is how it encrypts your searches as well.

In Zoho’s free email plan, you get 25MB of attachment storage, 5GB of overall storage, and free web and mobile app access using Zoho’s apps.
