Like I said, most ESP (email service providers) have the capability of creating automated email workflows. So, instead of getting an email subscriber and initially sending them one or two emails, before getting distracted and forgetting all about them, you can be sure that you have emails sent to them over the course of a few days, weeks, months etc. with email automation.
Email marketing has the highest conversion rates of any marketing channel. In fact, sixty-six percent of online consumers made a purchase after receiving an email marketing message — which is more than social and direct mail, according to the Data & Marketing Association. And transactions from email are three times more profitable than those made on social media, reports the global management consulting firm McKinsey & Company.
