Marketers should be concerned about the carbon emissions associated with email marketing for several reasons. Firstly, there is a growing awareness and concern among consumers about environmental issues. Companies that are seen as environmentally responsible can improve their brand image and customer loyalty. Secondly, reducing carbon emissions can lead to cost savings in the long run, as energy-efficient practices often reduce operational costs. Lastly, there is increasing regulatory pressure to adopt more sustainable practices, and businesses that fail to comply may face penalties.
