Based on pricing data only. Review the full comparison below for your specific needs.
Try Customer.io freeFrom $100/moWhich Should You Choose?
Choose Amazon SES if:
- •You need the cheapest possible transactional email at scale - SES costs $0.10 per 1,000 emails
- •Your engineering team is comfortable building custom email logic on top of raw infrastructure
- •You're already on AWS and want native integration
Choose Customer.io if:
- •You need a behavioral messaging platform that tracks real-time events and triggers emails accordingly
- •Customer.io handles complex branching logic across email, SMS, push, and in-app messages
- •Your product team needs to send personalized lifecycle emails without building infrastructure from scratch
Customer.io sits between raw infrastructure and full marketing platforms - it's built for product teams who need behavioral event-driven messaging. SES is raw infrastructure. Customer.io provides the event tracking, segmentation, and workflow logic that SES lacks, while staying developer-friendly. For product teams that want behavioral lifecycle emails without managing raw infrastructure, Customer.io is the right level of abstraction. SES is only better if you're building all that logic yourself.
