What It Is

NOTsoFASTmail.com is an unconventional email relay service. Its goal is not to speed up delivery, but to “slow email down.” Users continue using their existing email client; they only need to rewrite the recipient address into a format such as [email protected]. The message is first stored by the service and then forwarded to the real recipient roughly three days later. Its design philosophy leans toward personal letters, slow communication, and anti-instant messaging, rather than enterprise communications infrastructure.

Core Capabilities and Integration

In terms of channels, it covers email only, with no SMS, voice, or IM support. Integration is extremely lightweight: there is no software to download, no need to reconfigure the mail client, and no requirement to register for an API or SMTP service. In essence, routing is handled through address rewriting. The recipient will see that the email was delivered via NOTsoFASTmail.com and how long the delivery took. The reply address is also processed so that replies continue to pass through the service, maintaining the slow communication chain.

Deliverability, Performance, and Compliance

The service’s “performance” is intentionally slow, with the website explicitly showing a delivery time of about three days. However, it does not disclose deliverability rates, queue reliability, availability, failure retry mechanisms, anti-spam policies, or any SLA. Its operational notes are also quite candid: the system was built by an individual in 2010, has zero employees, runs on a server in a living room, and warns users not to entrust important messages such as wedding invitations to it. On privacy, it only states that it will take care to protect data, while also admitting that it has limited ability to resist scenarios where servers and emails are forcibly obtained by external parties. There is no visible information on GDPR, encryption, data retention, or enterprise compliance.

Pricing, Pros, and Cons

The crawled text does not provide a pricing model, rates, or payment methods, so its commercial pricing cannot be assessed. Its advantages are a distinctive concept, a low barrier to use, no need to change existing email tools, and the ability to bypass the delay at any time by sending directly to the original address. The drawbacks are equally clear: it lacks enterprise-grade reliability, customer support, compliance, APIs, analytics, and security capabilities. It is not suitable for transactional email, marketing email, notification email, or any time-sensitive communication.

Who It’s For and Access from China

It is suitable for individual users who want to experiment with slow personal letters, creative projects, or non-instant communication with friends and family. It is not suitable as business email infrastructure. The text does not provide information on access from mainland China, and payment methods are also unknown. If stable service is required, consider scheduled sending features in conventional email services, or use a mature transactional email or email marketing platform instead.
