Customer.io pricing
What Customer.io costs
Customer.io starts at $100 a month on its cheapest paid plan, rising to $1,000 on the highest plan it publishes.
That is above the Email Marketing median of $33 — it is priced at the expensive end of its category.
The plans are called Essentials, Enterprise and Premium.
No free tier and no trial length is published, and the top tier is quote-only, so enterprise pricing is not public.
No price on this page has changed since 05 Aug 2026, when Customer.io was first read. A price that has held is worth knowing before you commit to a year of it.
