Email marketing has evolved rapidly alongside the technological growth of the 21st century. Prior to this growth, when emails were novelties to the majority of customers, email marketing was not as effective. In 1978, Gary Thuerk of Digital Equipment Corporation (DEC) sent out the first mass email to approximately 400 potential clients via the Advanced Research Projects Agency Network (ARPANET). He claims that this resulted in $13 million worth of sales in DEC products, and highlighted the potential of marketing through mass emails.
Drip offers a very small forever free plan, along with a two-week free trial for the Basic and Pro membership levels. If you choose to continue service after those two weeks, then your card will be charged. There is a 30-day refund window from when you start your service, but it’s up to the discretion of Drip whether you will receive a full refund.
