Quick answer — which should you choose?

Customer.io's Essentials plan starts at $100 a month for 5,000 profiles, with each additional 5,000 profiles adding roughly $90 to $100, and Premium starts around $1,000 a month on an annual commitment. Bluey bills on emails sent: 10,000 contacts emailed weekly — 40,000 sends — is $30 a month on Grow. Customer.io is genuinely more powerful for complex, multi-channel, data-heavy lifecycle messaging, and if you need that power it is worth the money. Pick Customer.io when message logic is a core part of your product; pick Bluey when you need strong lifecycle email without a platform that expects an engineer to own it.

Why teams move

Three things that come up in every conversation.

01

Profile-based billing charges for data you are not messaging

Customer.io bills on profiles in the workspace. Every trial signup, every imported record, every user who churned two years ago is a billable profile. Send-based pricing charges when you actually send.

02

The power only pays off if someone wields it

Customer.io's depth — Liquid templating, data pipelines, complex journey logic — is real, and it assumes a technical owner. Teams without one routinely pay Premium prices for Essentials-level usage.

03

Acquisition lives somewhere else

There are no landing pages or forms, so you need another tool for the top of the funnel. Bluey covers capture, nurture and send in one place.

Being straight with you

When Customer.io is the better choice.

Customer.io is a genuinely excellent platform. If these describe you, it is worth every cent:

Messaging logic is part of your product — complex, data-driven journeys are a core capability, not a marketing task
You need real multi-channel orchestration across email, SMS, push and in-app in one journey
You want your data warehouse as the source of truth, synced both ways
You have a growth engineer or lifecycle specialist who will own the platform
Enterprise governance, permissions and scale are hard requirements

Bluey does not try to be Customer.io. If you need that depth, buy it. If you are paying for it and using a fraction, that is the case for switching.

Switching from Customer.io? Here is the short version.

Customer.io to Bluey means simplifying deliberately: profiles and attributes import, and complex journeys are rebuilt as the smaller number of flows that were actually earning.

1Export people with attributes and segment membership from Customer.io
2Import into Bluey; attributes map to custom fields, segments are rebuilt on the same data
3Identify the campaigns that actually drove revenue and rebuild those first — most workspaces have far fewer than they think
4Repoint your event tracking at Bluey, then re-authenticate the sending domain and ramp volume

FAQ

Bluey vs Customer.io, answered.

How much does Customer.io cost?

Essentials starts at $100 a month for 5,000 profiles, with roughly $90 to $100 added for each additional 5,000. Premium starts around $1,000 a month on an annual commitment. At 10,000 profiles you are looking at roughly $190 to $200 a month on Essentials.

Is Bluey as powerful as Customer.io?

For behavioural email, Bluey covers the ground most teams use: event triggers, branching automations, behavioural segmentation and revenue attribution. For multi-channel orchestration, Liquid-level templating control and warehouse data pipelines, Customer.io is meaningfully deeper and we are not going to pretend otherwise.

Does Customer.io do SMS and push?

Yes — email, SMS, push and in-app messages in a single journey. Bluey is email only today. If multi-channel orchestration is a requirement rather than a wish, that is a genuine reason to stay.

What is a profile and why does it matter for the bill?

A profile is any person record in your Customer.io workspace, whether or not you message them. That includes churned users, unconverted trials and imported records. Because billing is per profile, workspace hygiene becomes a cost-control exercise. Send-based billing removes that job entirely.

Do I need an engineer to run Customer.io?

Realistically, yes — or at least someone comfortable with Liquid, event schemas and API-driven data. That is a fair trade for the power on offer, but it is a cost that does not appear on the invoice, and it is the most common reason teams end up paying for capability they never use.
