Overview
Zoho Campaigns and Customer.io are fundamentally different tools. Zoho is affordable, straightforward email marketing. Customer.io is enterprise-grade behavioral messaging that requires engineering to implement. Your team's technical resources and complexity needs determine the right choice.
The Complexity Gap
Zoho Campaigns is designed for marketers. You can be up and running in hours, sending campaigns and basic automations without touching code.
Customer.io is designed for product-led companies with engineering resources. Full value requires sending user events from your product, building complex workflows, and potentially implementing multiple messaging channels. Setup takes days to weeks.
Multi-Channel vs Email Only
Customer.io supports email, push notifications, in-app messages, and SMS from one platform. You can build workflows that reach users across channels based on behavior.
Zoho is email only. For push or SMS, you need additional tools and integrations.
Behavioral Automation
This is where Customer.io shines. Trigger messages based on any user event: feature usage, page views, in-app actions, API calls. Build complex conditional logic with multiple branches.
Zoho's automation is based on email engagement and contact properties. Good for marketing campaigns, limited for product-led user journeys.
Price Reality
At 10,000 contacts, Zoho costs $35/month. Customer.io's pricing is based on profiles and messages, but expect around $150/month or more at similar scale with meaningful usage.
That 4x price difference reflects the power difference. If you need Customer.io's capabilities, it's worth it. If you need basic email marketing, it's overkill.
For SaaS Companies
Customer.io is powerful but requires significant investment to implement well. Zoho isn't built for SaaS.
If you want SaaS-specific features without Customer.io's complexity, consider Sequenzy. Native Stripe integration enables automation based on subscriptions without custom engineering. At $49/month for 10k contacts, it's between Zoho's simplicity and Customer.io's power. AI sequences help create content, and both transactional and marketing emails work from one platform.
