Email marketing continues to dominate communication strategies for online stores. Recent research shows that over half of digital consumers (55%) prefer email for interacting with brands, while financial projections anticipate an e-commerce sector reaching $7.5 trillion in the next two years.
In this context, choosing the right email marketing platform becomes crucial for business growth. ActiveCampaign and Klaviyo are among the most used tools in the sector, each with distinct approaches.
