Usage & Billing
As many as you want! In fact, we encourage all team members to use Customer.io for consistent messaging across all of your product and marketing sends.
Our customers can choose where they would like to store their data, in a US or EU data center, during sign-up.
Not a chance. We happily store all of your data, so whenever you are looking to run advanced analysis in your BI tools, you’ll have immediate access to anything that’s ever happened in your Customer.io account. Our competitors don’t do this, or they charge a premium.
We charge you based on the maximum number of uniquely identified users (profiles) in your account. On the anniversary of your subscription, we will charge the method of payment on file in USD. We include a million messages per month on the essentials plan, any messages above that will be charged at a nominal rate.
You can start integrating and adding data to Customer.io immediately after sign-up. To help combat spam and fraud, we manually review each account before any outbound messages can be sent. This helps maintain our reputation and protects all of our customers.
All plans include 1,000,000 emails and unlimited in-app messages, push notifications, SMS, and webhook messages. A fair use policy of 60 non-email messages per profile per month ensures that all users have a fair and equal opportunity to reach their target audiences. If you exceed this limit, your messages may be blocked or delayed. You may also receive a warning or be suspended from the platform. If you have any questions about the fair use policy, please contact us at firstname.lastname@example.org.
For monthly subscriptions, we only accept payment by credit card. Annual subscribers have the option of receiving an invoice, which can be paid via ACH or Wire.
