Possible disadvantages of FastMail

  • Cost
    FastMail is a paid service, which might deter some users who are accustomed to free email services like Gmail or Yahoo.
  • Limited Free Tier
    Unlike some competitors, FastMail does not offer a free tier, meaning users have to commit financially from the get-go.
  • No E2E Encryption
    FastMail does not provide end-to-end encryption by default, which may be a drawback for users seeking maximum security for their communications.
  • Complex Interface for Beginners
    While feature-rich, the interface may be overwhelming for users who are not technically inclined or are new to email management.
  • Limited Integration
    FastMail may not integrate as smoothly with some third-party services and applications when compared to giants like Google Workspace or Microsoft Office 365.

JsonAPI features and specs

  • Standardization
    JSON:API provides a standardized format for building APIs, which promotes consistency and interoperability between different APIs.
  • Efficiency
    It supports features like sparse fieldsets, compound documents, and included relationships which help in reducing the amount of data transferred and improving response times.
  • Decoupling
    JSON:API encourages a clear separation between client and server, allowing them to evolve independently as long as they adhere to the specification.
  • Error Handling
    It has a well-defined error format that makes it easier for clients to understand what went wrong and how to fix it.
  • Community and Tooling
    A growing community and increasing tooling support make it easier to implement JSON:API in various server-side and client-side technologies.

Possible disadvantages of JsonAPI

  • Complexity
    The specification can be complex and may introduce a learning curve for developers who are new to it or used to simpler REST approaches.
  • Overhead
    Strict adherence to the JSON:API specification can sometimes introduce additional overhead in terms of implementation effort, especially for small projects.
  • Flexibility
    While the standardization is beneficial, it can reduce flexibility in scenarios where a more customized or optimized solution is needed.
  • Adoption
    Although growing, JSON:API is not as widely adopted as other conventions like simple REST, and thus some developers and projects might resist switching to it.
  • Resource Intensive
    Some features of JSON:API, like relationship links and included resources, can become resource-intensive for the server if not implemented carefully.

Moving away from GMail
Fastmail was my top choice, from a usability perspective and I read many good reviews of it. It ticks all the boxes, at a cost of 50$ per year. I evaluated it a year ago, but because the construction of my house started, I put the email migration project on hold.

    I too use a catchall address... And I'm always disappointed when Fastmail doesn't take all of the addresses that I get email sent to, and turn them into masked emails automatically!

  • GraphQL vs REST: 18 Claims Fact-Checked with Primary Sources (2026)
    REST does not define a standard batching mechanism at the protocol level. When batching is needed, it is handled through API design (such as bulk endpoints), infrastructure, or framework-specific solutions. Some specifications attempt to address this, such as ODataโ€™s batch format or JSON:APIโ€™s compound documents, but adoption is inconsistent. - Source: dev.to / 4 months ago
