Email marketing is a tool that allows you to build a long-term relationship with your customers and subscribers through constant communication and personalized content. A way to grow even closer with your customers is to use a special date or event as a reason to send gifts, discounts or prizes. This kind of gesture shows how much you care about your subscribers and also makes you stand out from your competition. To strengthen the bond between you and your customers, be sure to highlight their needs and interests. In order to do this successfully, you’ll need to know your audience very well.
