Email marketing costs are on the rise due to several factors. Firstly, the need for more sophisticated tools and platforms to manage and optimize campaigns is increasing. Advanced analytics, segmentation, and personalization features come at a higher price. Secondly, escalating competition requires businesses to invest more in creative and effective strategies to stand out in crowded inboxes. Lastly, regulatory compliance such as GDPR and CAN-SPAM Act has added additional layers of complexity and cost to campaigns.
