What's new:
Non-Unique Emails is now in Open Early Access and rolling out to all environments. With this feature, multiple user accounts can share the same email address within a database connection. This enables support for real-world scenarios like:

  • Parent/child accounts using a shared inbox

  • Small businesses with a single location email

  • Users managing multiple roles under one email address

Key details:

  • Rollout has just begun and will take 1--4 weeks to reach every environment.

  • Available only for new database connections.

  • Email cannot be used as a primary identifier, customers must configure username or phone number.

  • Email communications will still be delivered to the shared email.

  • Once enabled, the non-unique email setting is permanent.

Status:

  • This feature is production-ready.

  • No opt-in required, all customers will gain access once rollout reaches their environment.

  • GA planned for Q4 2025.

Getting started:
Customers can create a new database connection with Non-Unique Emails in the Dashboard or via the Management API. See full documentation here:
