We unify your data, messaging, and AI into a single platform, so every interaction with your customers is stronger and more relevant than the last.
Messaging for the whole lifecycle
Send messages through all major marketing channels—email, SMS, in-app, and push—within one platform at no extra cost. Customer.io’s intuitive visual workflow builder makes creating multi-channel campaigns simple, unlike Marketo's clunky builder, which often requires engineering support. Plus, Marketo charges additional fees for sending SMS and push notifications.
World-class customer support
Benefit from Customer.io’s top-notch technical support team, offering email and live chat assistance with a 99% CSAT score. Start strong with a 90-day onboarding process and a dedicated Customer Success Manager to help with setup and strategy. Conversely, Marketo reserves its technical experts for higher-tier customers, leaving others without essential support and guidance.
Unlimited messaging automation
All plans include unlimited user seats, segments, attribute storage, events, event segments, workflow triggers, non-email sends, data warehouse sync, and access to our full reporting and analytics suite to power data-driven marketing decisions. Marketo limits the usage of basic campaign-related features like users in a workspace, API calls, custom objects, and custom fields, which are often limited by quantity and gated by plan type.

Customers love us
Preferred by product-led companies
After evaluating Customer.io and Braze head to head, we decided to go with Customer.io for the ease of integration, transactional messages, our mobile capabilities especially push notifications, and for the support we know we would get.
Ivar Arulaid
Marketing Operations & Automation Manager
With the flexibility and interoperability of Customer.io we’ve been able to build some truly insane and elaborate onboarding flows. If a colleague asks me if Customer.io can do something cool, no matter what they ask my immediate answer is always, “Yes. Yes it can.” I love always having the answers!
Ammon Brown
VP of Growth
Messaging frequency is key for our strategy. We can’t email our customers daily, so increasing frequency with a multi-channel strategy is how we can scale message volume. The conversion rates prove that strategy is working.
Ugo Iwuchukwu
Head of Marketing
