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
