Customer.io or Braze — which should you use?
Customer.io is the right answer for almost any company under about 100 people: event-driven campaigns, published pricing, an interface a marketer can run. Braze is for consumer apps at scale with in-house lifecycle teams and an enterprise budget. Customer.io starts at Essentials from roughly $100/month (free tier: Free trial rather than a free tier.); Braze starts at Quote only, typically five to six figures annually (free tier: None.). Prices are list prices and change, so check the vendor pages before buying.

Both send messages triggered by what people do rather than what list they're on. Both cover email, push, in-app and SMS. The difference is scale, price and how much of the platform you'll actually use.
Braze doesn't publish pricing, which is itself the answer to whether it's aimed at you.

The differences
Where they actually diverge.
| Feature | Customer.io | Braze |
|---|---|---|
| Published pricing | Yes | No |
| Entry cost | ~$100/month | Enterprise contract |
| Channels | Email, push, SMS, in-app, webhooks | Same plus more, at higher scale |
| Who runs it | One marketer plus occasional dev help | A lifecycle team |
| Best fit | B2B SaaS and growing apps | Large consumer apps |
Pick one
Which one fits you.
Choose Customer.io if
- You have engineers who can send events but no lifecycle team
- You need pricing you can approve without procurement
- Email and in-app cover most of your messaging
Choose Braze if
- You send millions of push notifications a month
- Multiple regional teams need governed access
- You need the vendor to sign an enterprise agreement
When neither is the answer
Pre-product-market-fit, a transactional email API plus a spreadsheet of triggers is enough. Lifecycle platforms pay off once you know which behaviours predict retention.
Questions
Common questions.
Do I need a CDP as well?
Not initially. Both can ingest events directly from your app. A CDP earns its place when three or more tools need the same event stream.
What's the cheaper alternative?
For B2B SaaS specifically, Loops or Customer.io's entry tier. For very early products, transactional email triggered from your own code costs almost nothing and covers onboarding.
Prices are list prices published by each vendor and change often — check the linked pricing pages before you buy. We take no affiliate commission and nobody pays to appear here.
