Customer.io shows three plans: Essentials from $100 per month billed monthly, Premium from $1,000 per month billed yearly, and Enterprise through sales. Seats are unlimited, so profiles set the bill, as of Nov 2026.
| Plan | Price as shown | Billing basis | Main limit | Who it suits |
|---|---|---|---|---|
| Essentials | starts at $100 per month | Billed monthly (plan term: Monthly) | 5k profiles (people + objects); 1 million emails per month; unlimited user seats | For teams getting started with data-driven messaging |
| Premium | starts at $1,000 per month | Billed yearly (plan term: Annual) | Custom profile and email volume; 10 object types; unlimited workspaces | For teams scaling across channels with custom workflows |
| Enterprise | Let's talk (Talk to sales) | Annual | Custom limits | For organizations that need dedicated infrastructure and support |
Customer.io is a messaging platform for data-driven email, push, SMS and in-app campaigns, built around a visual workflow builder. The table shows its plans as listed, as of Nov 2026. Note the billing basis: Essentials is billed monthly, while Premium and Enterprise aren't: they're on annual terms.
Profiles, not seats: the surprise in the bill
Seats are unlimited on every plan, so adding teammates won't move the figure. The price lever is profiles, which the page defines as people plus objects. The $100 Essentials entry covers 5k profiles, and additional profiles are $0.009 each on Essentials.
That's a small number per profile, but it'll apply to every one above 5k, and objects count as well as people. If you sync accounts, companies or other objects into Customer.io, they'll sit in the same total.
The bigger step is the jump to Premium. It starts at $1,000 per month on an annual term, and profile and email volume are custom, with no published per-profile rate. So once you're past Essentials, the bill is a conversation with sales rather than a figure you can work out from the page.
Upgrading across Customer.io plans
- Essentials: 5k profiles, 1 million emails per month, 2 object types, 2 workspaces and unlimited user seats, with an AI Agent with core execution skills, the visual workflow builder, email and community support, and basic data integrations.
- Premium: everything in Essentials, with custom profile and email volume, 10 object types and unlimited workspaces, plus elevated Agent limits and custom skills, Daily Routines for scheduled tasks, premium chat and email support, 90-day onboarding support, HIPAA compliance and premium data integrations.
- Enterprise: everything in Premium, with what the page calls its best pricing on profile and email volume, priority technical support, audit logging and data governance, migration support, a dedicated customer success manager, a dedicated technical implementation specialist and a shared Slack channel.
The triggers the page lists for moving up are profiles above 5k, needing more than 2 workspaces or 2 object types, and needing HIPAA compliance, custom agent skills or audit logging, which all sit above Essentials.
Add-on rates on the page
Three add-on rates are printed. Additional people and object profiles are $0.009 on Essentials, and custom on Premium and Enterprise. Additional 1,000 emails are $0.12 on all plans. Additional AI credits are $10 / 100K, negotiated on Enterprise.

Plain advice from Customer.io's page
The page shows unlimited seats on every plan, with tiers separated by profiles, workspaces, object types, support and compliance. Essentials starts at $100 per month billed monthly for 5k profiles, with extra profiles at $0.009 each; Premium starts at $1,000 per month billed yearly with custom volume; and Enterprise is a sales conversation.
So the number you'll want to bring to the page is your profile count, people and objects together. That's what decides whether Essentials' published rates apply, or whether you're into custom pricing on an annual term.
