Zapmail

Zapmail is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Zapmail rather than just read about it. In short: Zapmail was a service, launched in 1984 by Federal Express (FedEx) whereby fax transmission was offered to customers as a means to expedite delivery of documents. This was before the widespread availability and use of fax services in homes and businesses.

Key takeaways

  • Zapmail belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Zapmail to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Zapmail from memory before moving on to harder problems.

Reference excerpt

Zapmail was a service, launched in 1984 by Federal Express (FedEx) whereby fax transmission was offered to customers as a means to expedite delivery of documents. This was before the widespread availability and use of fax services in homes and businesses. Eventually judged a commercial failure, it was discontinued just over two years later.

History Zapmail was offered at two levels of service. When sending documents in low volumes for customers, FedEx would collect the document as normal, bring it to the local depot where it would be sent by fax to a depot near the recipient's address. There the document would be printed, packaged and delivered to its destination. For higher volume users, FedEx would install a “Zapmailer” fax machine in the client's premises, usually in the mail room. To provide the fax network, FedEx had to invest heavily in fax machines from NEC, which at the time were expensive. Additionally, rather than use the PSTN public phone network, the documents were carried over the company's own packet-switched network, requiring still more investment. The FedEx strategy was driven by an expectation that customers would pay a premium to have their documents delivered in hours instead of overnight. At the same time, by migrating document traffic from trucks and aircraft, significant savings could be made in the FedEx transportation network. These savings could later be used to offer discounted services to increase volumes and margins. The Zapmailer did not conform to the ITU-T (formerly CCITT) specifications which had been developed for fax transmission over public networks. This meant the Zapmailer could not communicate with the growing numbers of Group 3 fax machines entering service. Large clients in particular, and later most others, were able to buy their own fax machines and transmit documents themselves. Once this began to happen, customers could see that it was more cost effective to buy their own machine rather than pay for regular Zapmail services. This remained true despite price reductions from $35 to $10 per ten pages. Quality problems with both the equipment and the transmission lines led the company to stop taking orders in March 1986. At that time the company stated that losses had accumulated to $200m and that an equipment upgrade was required. It was also stated that the “last mile” transmission would be carried by satellite. This plan could not be realised due to the destruction of the Space Shuttle Challenger and the resulting grounding of the shuttle fleet. It was further announced in August that the upgraded equipment would be compatible with Group 3 fax standards. By this time, machine deliveries from NEC numbered in the thousands while customers were only in the hundreds. It was decided the service was a commercial failure and it was discontinued in October. $320m was written off and the employees of the Zapmail service were re-deployed within the company.

Drawbacks Color and high resolution images could not be transmitted Confidentiality – the uncovered documents had to be handled by FedEx employees at both ends of the fax transmission In some cases, there was customer confusion of how the service worked Fax machines, like many examples of electronic equipment, became affordable even for smaller companies Problems such as inability to transmit light toned originals and telephone line limitations persisted Because the service was still centered on the mailroom, often the speed advantage was lost in the internal mail system Machines were not compatible with public networks

Worked examples

Example 1 — a first encounter with Zapmail

Start with the simplest possible case. Write down what Zapmail claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zapmail before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zapmail ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zapmail

In research
Zapmail appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Zapmail in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Zapmail is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1984 introductions, Express mail, FedEx, so understanding it makes those chapters shorter.
In everyday life
Look for Zapmail outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Zapmail in simple terms?

Zapmail was a service, launched in 1984 by Federal Express (FedEx) whereby fax transmission was offered to customers as a means to expedite delivery of documents. This was before the widespread availability and use of fax services in homes and businesses.

Why does Zapmail matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Zapmail?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
