As part of our ongoing branding unification efforts, we're updating the sender domain for Signal Sciences email communications.

Effective July 28, 2025, emails previously sent from `support@signalsciences.com` will be sent from `no-reply@fastly.com`. All official communications will come from `@fastly` domains.

This change aligns with our unified brand identity and does not impact your Signal Sciences services. Your service experience, data, and access remain unchanged.

To ensure you continue receiving all important notifications and updates, we recommend updating your email filters and allowlists to reflect this change. If you have questions, our [support team](https://support.fastly.com) is here to help.
