Study on Consumer Attitudes Toward Email and Postal Direct Mail
Posted by Hendry Lee on 02/2/07 in Survey and Trends
Journal of Interactive Advertising has published an academic paper studying email and postal direct marketing. If you enjoy reading scientific studies, this paper is a good read.
Here are the hypotheses drawn from this study:
- Consumers are likely to find spam more intrusive than direct mail.
- Ad intrusiveness caused by a) spam; b) postal direct mail negatively correlates with attitudes toward the advertising technique.
- The level of perceived loss of control by consumers will be greater for spam than direct mail.
- Perceived loss of control mediates the relationship between ad intrusiveness caused by spam and ad irritation.
- Consumers are likely to experience a higher level of advertising irritation from spam than direct mail communications.
- The degree of advertising irritation caused by a) spam; b) postal direct mail is negatively correlated with attitudes toward the advertising technique.
For methods of measurements, refer to the paper for details.

It seems odd that postal advertising is perceived as less irritating than spam. I personally feel the other way. With spam I can ignore it, delete it, block the sender or unsubscribe with little required effort.
Postal mail however is much harder to unsubscribe from. I also hate the fact that energy and resources have been used to make print and deliver something to me that I then throw away without reading only to require more energy and resources for it to be taken away and disposed of or recycled.
