Verizon Media's engagement feeds offer valuable insights into user engagement and deliverability issues, providing metrics on complaints, spam traps, and authentication. Their usefulness to ESPs and clients varies. Some find the aggregated data beneficial for identifying campaigns needing review, while others, particularly smaller senders or those lacking analytical resources, may find them less valuable. A key limitation is the lack of direct integration with common email marketing platforms, necessitating manual processing. The actionability of the data depends on the recipient's ability to turn it into practical improvements, and they are more granular than traditional feedback loops.
