When it comes to ecommerce, email continues to bring the heat.

A new Klaviyo study, entitled The Ecommerce Marketing Mix Report, has email marketing as the most used marketing channel, followed by organic social, paid social, and SEO. (Print, unfortunately, was the fifth-least used channel.)

Email marketing was, for 76.86% of the businesses surveyed, in the Top 3 for ROI-generating channels, followed by paid search, paid social, broadcast, and SEO.

“Marketers are leveraging a healthy mix of email marketing strategies,” according to Klaviyo, “including automation (27.55%), campaigns (26.65%), personalization (23.08%), and segmentation (22.72%) — almost an even split across the board.”
