Anthropic receives content only when you use the AI Editor, or content you choose to share with the in-app AI Support Agent. Normal sending through the Emails API is not sent to Anthropic. RunPod processes a small sample of emails for trust and safety, on dedicated infrastructure that Resend operates. Neither Resend nor these subprocessors use customer content to train or fine-tune models. See the GDPR overview for details.
A list of subprocessors can be viewed at resend.com/legal/subprocessors. We give at least 14 days' notice before adding or replacing a sub-processor. See the GDPR overview for notice and objection details.
