Signing up for your product is easy.

But so is never coming back.

Make the most of all the work you're doing to acquire new users, instead of letting them slip away before they even get to know you.

Marketing for web and mobile apps, SaaS, and subscription services is an ongoing process of building relationships.


Your job isn’t over after people sign up for an account.

Engagement-driven products don’t run on batch-and-blast coupon codes. Say hello to the fine-tuned control you need to engage people at a one-to-one level, but at scale.

Map customer communication directly to your funnels with Customer.io. Leverage real-time user data and events to segment and personalize with precision.

Send relevant messages that boost trust, conversions, and retention—all without having to bother developers or juggle lists.


Keep people coming back with nurturing messages, converting users to happy customers.

Message Happier

Customer.io powers:

Convert users to customers

Nurture people through successes to persuade them to subscribe and stick around.

Spur conversions when the opportunity strikes, based on behavior or trial periods.

Maximize retention

Customer retention efforts are less expensive than acquisition. Keep more customers and reduce churn.

Prevent inactivity, win back and re-engage users, and react before you lose them.

Target your promotions

Send messages that matter to precise segments of people and boost the effectiveness of your promotions.

From upsells, offers, and engaging updates, you're in control of reaching the right people.
