The development of digital marketing is inseparable from technology development. One of the first key events happened in 1971, when Ray Tomlinson sent the first email, and his technology set the platform to allow people to send and receive files through different machines.[9] However, the more recognizable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computers was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker.[10] These kinds of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not as efficient.
