Customer.io has the best ways to segment customers. We use Segment to send email analytics to Amplitude and Customer.io. Customer.io takes all that information, and then we can build different lists for customers who are on different plans, or who have used particular features. They have very good tools to do that, and then we send people very personalized marketing newsletters.

We tried to use Customer.io but we felt that it lacked on the user interface.

Customer.io is a great tool. It’s awesome for managing emails, and for creating personalized emails, thanks to its Liquid language support.

Customer.io - Best Email Marketing Tools for Startups

Customer.io is an email marketing service that focuses on transactional emails (communications that automate customer service, like receipts or UPS tracking updates) and trigger emails (those that are a direct response to a user request or site visit, like signing up for a newsletter, being inactive for a specified period of time or updating their profile). It’s a technical and highly customizable tool that can really add value to complex email marketing workflows, though it’s not known for its speed and ease of use. It’s often the first choice among startups with hyper-specific segmentation needs.

Which startups use Customer.io?

Customer.io is most popular among small to midsized B2C startups, with a well-defined marketing funnel and enough technical support on hand to manage the implementation and customization of this complex and powerful tool.

How much does Customer.io cost?

Customer.io’s basic (and free!) package includes 200 profiles and 400 monthly emails, and offers four upgrade possibilities with much greater capacity: $50 per month for 5,000 profiles and 10,000 emails; $250 per month for 50,000 profiles and 100,000 emails; $750 per month for 250,000 profiles and 500,000 emails; and finally $1,250 per month for 500,000 profiles and 1 million emails.
