Customer.io allows small to mid-size B2B and B2C companies to send triggered or segmented, contextual marketing or transactional (e.g. payment receipts) emails. Customer.io supports A/B Testing, timed messages, multi-touch automated email campaigns based on a trigger event or segment membership (or both), and the requisite conversion tracking to capture what worked. Segmentation assimilates information from events, profile data, message activity, and page views to locate the best customers who are profiled in detail.
Customer.io offers a free, 30-day trial, and pricing starts at $150 for 12,000 profiles. Beyond this, Customer.io has tiered pricing through 50K profiles - and offers annual contracts starting at $1,000 a month
