Review Customer.io?
User reviews are sharply negative, describing Customer.io as hard to use for small teams, with a confusing interface, inflexible journeys, and a messy email editor that makes routine work painful. One user also says delivery and draft views do not show everything clearly. Founder feedback is thinner but more positive: the makers of IFTTT praise its behavioral triggers, segmentation, and multi-channel lifecycle messaging, while others say they use it broadly for lifecycle emails and user communication.
