Email security

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.

What to Consider Before Signing Up for a Secure Email Provider


Get a Secure Email App You Can Trust
  1. Type of Encryption Used.

    When signing up for a secure email provider, you should investigate the type of encryption used and how the company implements it. In addition, you should compare the encryption types to the other vendors you’re considering signing up for as your secure email provider.

  2. Data Center Location

    While the location of the data center might sound weird to consider with a secure email provider comparison, the jurisdiction the company is located in matters when it comes to security. If the data center is located in an area without strong privacy laws, the company could be forced to unlock the servers and encryption to local law enforcement.


    How vital location is with your decision on paid secure email providers will depend on your level of concern for your communications and privacy requirements.

  3. Security

    As we mentioned at the beginning of this article, security is of the utmost importance to Spike. We list our privacy policy to be clear and upfront with our customers. When looking at the top private email providers, investigate the security and privacy policies of the vendors you’re considering.

  4. Features

    Just because you want a secure email provider doesn’t mean you should ignore the need for next-generation features. For example, does the provider add on any collaboration tools? What about power-user features like scheduled send, snooze, etc.?

  5. Storage

    Email storage is essential with paid secure email providers because users will want to believe they have enough space for decades of messages, attachments, etc. Free providers are offering 5-15GB for free, so paid secure email providers should at least match that amount of storage is not provide a considerable amount more.

  6. PGP Support

    Pretty Good Privacy (PGP) is an email encryption system used to send encrypted emails and encrypt sensitive attachments. Since the invention back of PGP in 1991, it has become the default standard for email security worldwide.


    When researching secure email providers, consider which platforms and providers include built-in PGP support.
