SaaS Case Study Email Examples
A customer story sent as marketing. The structure is near-universal — problem, product, number — so what varies is the quality of the number and how specific the named customer is. Read a few hundred and the pattern becomes obvious: the persuasive ones name a person and a metric, the forgettable ones name an industry and a percentage. The subject line usually gives away which kind it is before you open it.
