Depending on the position, you might be running email marketing campaigns, so your interviewer will want to make sure you are familiar enough with the tools necessary to hit the ground running. Prior to your interview, be sure to scour the job description for any indication of email marketing and what platform they use. You'll often find these details in the qualifications section of the job description. Even if you don't have direct experience with the platform they use, you can research and draw connections to what you already know. If you don't see any specific details, then simply outline what platforms you have experience with and define what value means to you when selecting your favorite.
