Email Newsletters – These are regular emails that are sent to a list of subscribers who have chosen to receive updates from a company. Newsletters usually don't have explicit sales messages, but try instead to build a relationship between a customer and a brand. They often have a conversational tone and contain news and information that will be of interest to the customer. The goal is to keep a customer connected to a company even when they are not buying anything.
It's Timely: Study after study shows that email response rates decline over the age of the lead. In his Science of Timing research Dan Zarrella, HubSpot’s Social Media Scientist, discovered that there is a positive correlation between subscriber recency and CTR, one of the key metrics of engagement. You need to use lead nurturing campaigns to take advantage of this dynamic.
Email has been shown to generate a better ROI compared to other marketing channels. A survey by the Direct Marketing Association and Demand Metric of marketers in the United States showed that email achieved a median ROI of 122%, which was more than 4 times higher than other marketing channels, including social media (28%), direct mail (27%), and paid search (25%). And in 2016, email marketing generated $44 ROI for every $1 spent, which was up from $38 in 2015.
