Customer.io localization with Crowdin

Translate your Customer.io content with ease. Setup integration once, define your localization workflow and spend less time managing translations.

Customer.io is a cloud marketing automation system that allows users to send newsletters to selected segments of their customers using data from their website.

Features at a glance

• Supports localization of campaigns, newsletters, broadcasts, and transactional messages. Supported message types include Twillio SMS, Slack messages, email, and push notifications.
• Manual content synchronization before and after translation.
• Auto-sync of source content and translations.
• WYSIWYG file preview for translators.
• Quick sync and translation of even minor content updates, like a new sentence or a changed word.

Integration capabilities and considerations

There are a few important limitations to keep in mind before using this integration:

• Translation Selection Limitations: Due to limitations of the Customer.io API, Crowdin may display more campaign actions in the integration panel than can actually be translated. This includes actions that are not eligible for translation.

• A/B Testing: Customer.io does not support multilingual messages in A/B testing.

• Email Editor Compatibility: Only emails created using the rich text editor or code editor are compatible for translation. Emails created with the drag and drop editor cannot be translated due to the limitation of the Customer.io API.

• Locale Configuration: Make sure locales are configured in your Customer.io actions before uploading translations from Crowdin. If a Customer.io action does not have a corresponding locale that matches the sync, Crowdin will not be able to create or match it.

• Newsletter Sync Issues: There is a known issue with Customer.io that can result in a mismatch between the number of actions displayed for translation and the actual number in Customer.io. Always review and select actions in your source language during synchronization.

• Non-Translatable Content: Currently, transactional SMS and in-app messages cannot be translated due to limitations in the Customer.io API.
