The biggest challenge we faced while working on the email marketing campaign of Dr. CBD was the initial research. Since CBD was operating in a distinctive market with minimal industry players, we had to conduct the primary research ourselves. Throughout the study, we had to face several challenges as across social media, the word CBD or cannabis is prohibited, so we had to connect with the audience in code words. Moreover, the previous email marketing campaign Dr.CBD had, was managed poorly, and everything was jumbled. So, to start the process, we had to sort out the essential data and move forward with our campaign later.
