Through marketing via newsletters, you have the opportunity to reach potential, or current customers directly via their email inbox. The strength of this strategy lies in the ability to reach extremely specific demographics or interest groups, where each newsletter acts as a bridge between the brand and a well-defined target audience. Therefore, newsletters often also have higher engagement and click-through rates, which in turn leads to the easy predictability of the measurability and outcome of a campaign and therefore you can also calculate ROI (return on investment) even before starting a dispatch.
