Customer.io vs OneSignal FAQ
- Which one is cheaper?
- OneSignal is the cheaper option, starting at $19/mo vs $100/mo for Customer.io.
- Can I use either one for free?
- OneSignal has a free plan. Customer.io doesn't — you'll need to pay from day one.
- How do they charge?
- Both use a hybrid model, so the comparison is straightforward — it comes down to features and limits at each price point.
- Which one is a better deal?
- Depends on what you need. Customer.io: At $100/mo entry, Customer.io undercuts enterprise CDPs but prices well above lightweight email tools, positioning itself as the mid-market to upper-mid-market choice for teams that have outgrown basic ESPs. The 10x leap to Premium suggests they're not fighting for budget-conscious buyers at scale — they want teams willing to pay for sophistication. OneSignal: At $19/mo to start paid, OneSignal undercuts Braze and Iterable by a mile, positioning itself as the budget-friendly entry point for mobile-first teams who don't need a full CDP. They're clearly hunting startups and mid-market apps that got scared off by enterprise engagement platform price tags, while still leaving Enterprise on the table for bigger fish.
