In-App Messages

Automate your
in-app messages

Create on-brand experiences that embed seamlessly into your website and mobile app. Combine in-app messages with email, push, and SMS to build high-performing cross-channel campaigns.

A single platform for all your product and marketing messages.

When you design workflows that combine in-app messages with emails, push, SMS, and webhooks, the possibilities are endless. You can quickly spin up a test to learn which channel yields the highest conversion for your audience. Try for yourself with the interactive workflow builder below.

A nudge is all it takes.

When customers are in your app, you have their attention. Guide them to take actions that drive results. Avoid new user confusion with a personalized onboarding flow. Have a new feature your customers have been requesting? Trigger an alert on login.

Get immediate reactions when you deliver data-driven in-app messages.
Customer.io is the most intuitive and robust omnichannel messaging platform I’ve ever used. They beat the competition out of the water.

The capabilities and metrics you need.

Reduce reliance on developer resources with the no-code builder and smart, data-driven segmentation. Monitor metrics within workflows and adjust your strategy in real time. Build A/B and multivariate tests to determine what message and timing perform best.

Consistent branding

When you’re not the only one building messages, consistent branding goes out the window. The fix? Save standardized colors, fonts, and layouts for all your teams to use.

Build messages that feel on-brand with your overall user experience. Add multiple buttons, deep links, actions, lists, and more with a builder you’ll actually want to use.
