Last week, a certain Ideopian had a minor fender bender, which left a golf-ball size crater in her bumper. Three days later, a pile of mail arrives, including 8 letters from personal injury attorneys and 3 chiropractors, all triggered by the filing of a police report. Triggers work because they allow you to present tailored communication at the exact time your prospect wants it. Smart marketers are always looking for them. For example, high pollen counts trigger radio ads for allergy remedies, and weddings trigger campaigns for housewares. Every product or service has a trigger.
