Marketing
Customer.io
Behavioural messaging across email and push.
What it is
Customer.io sends messages triggered by what people actually do in your product, across email, push and in-app. Messages fire on product events rather than list membership, which is the difference between lifecycle messaging and a newsletter. It expects you to send it clean event data, so the setup cost lands on engineering before marketing sees value.

Pick it or skip it
Pick Customer.io if
- Teams getting started with behaviour-triggered messaging: Essentials starts at $100 per month billed monthly, with a visual workflow builder and basic data integrations
- Companies scaling across channels — Premium is $1,000 per month billed yearly and adds custom profile and email volume, Daily Routines and premium chat support

Skip it if

- Your audience grows fast: pricing is quoted per profile volume, so the bill tracks your contact count rather than your send count
- You want dedicated hardware, audit logging or a named Customer Success Manager; that is Enterprise and Enterprise is contact-sales
Our verdict
Powerful once your event tracking is in place. Without good events it is an expensive newsletter tool.
