What people say about us

"Using Customer.io has boosted our numbers in every imaginable way — from audience growth to engagement to conversion. They are literally helping us change lives around with world by making sure we have the best email tool available."
Grace Garey
Co-founder at Watsi
"It's crucial for our team to make onboarding as fast and painless as possible because teachers are super busy. Customer.io allows us to segment new signups based on their remaining action items and send our teachers finely tailored guidance based on their real-time status."
Brendan Appold
Director of Classroom Success at Motion Math
"We use Customer.io for sending all transactional and outreach emails. Their support team is WOW. They've completely raised the bar for my support expectations from other SaaS companies. They are instant, descriptive, knowledgeable and hustlers."
Pratik Agarwal
Product Manager at Remind
"Customer.io dramatically improved the way we communicate with our customers. The app is extremely simple to set up and use, allowing any of our staff to easily create and send meaningful email campaigns. We have seen a 20% increase in our conversion rate, have gained significant insight into our customers' habits, trends, and needs, and formed more personal relationships."
Ben Buckwold
CEO at Red River Press Inc. & ESLLibrary.com
"Customer.io allowed us to easily set up drip campaigns that increase the activation rate of new signups and, ultimately, our bottom line."
Steve Klein
CEO at StatusPage.io
"We like Customer.io because it lets us automate all sorts of emails throughout our application without having to mess with application code. Our marketers or product people can go right in and set up a triggered email based on any event that we're tracking. It basically replaces building our own in-app email system for us."
Mattan Griffel
CEO at One Month

Industries

We serve data-driven internet businesses who nurture ongoing customer relationships and need to send personalized messages at scale across industries like:

Software as a Service (SaaS) and Subscription Services

Creating the best experience for your customers is a priority when your business runs on cultivating recurring engagement. With our robust logic engine, move people along your funnel with lifecycle messages that convert.

Consumer

B2C companies need a grown-up messaging platform that can provide sophisticated targeting and personalization power while being able to handle scale. Serve millions of customers while giving them a one-to-one experience.

Education Technology

Get students and teachers active with relevant, timely messages. Nurture learning and contributor engagement as you build vibrant, educational resources, connections, and communities.

Mobile Apps

Get in touch with people after they've left your app. Reach out to inactive users to bring them back when they're not logged in, get the word out for app updates and promotions, and send transactional messages.

Marketplaces and Communities

Coordinate, onboard, and engage through automated guidance, processes, activity summaries, and notifications. Take advantage of low-touch but powerfully personalized messages to manage contributor communities and two-sided networks without costly manual coordination.


Your Support Team

Case Closed!

We take our customer's success (incredibly) seriously here, and with a 95% happiness score we think our support team is making amazing things happen. Every customer has access to email support, and will hear back within 24 hours.

Setting Records

In 2016, our support team resolved half of all cases on the first reply. Extraordinary? Almost as extraordinary as our average resolution time of 13 hours. That means customers could enjoy an answer with their morning coffee.
