send()

We do not warm domains. We do not rotate IPs. We hand the approved email to whatever you already use.

Inputs and outputs

In. Approved email plus your SMTP/IMAP credentials or your provider integration.

Out. Send confirmation, message-id, and the timestamp the message was accepted by your relay.

Current version

v1.9.0 Forkable through the prompt library.

Model defaults

None. You can override per stage in your routing config.

How it fails

Send failures break down into three buckets. Authentication, content rejection at your relay, and remote-bounce. Each is logged with the raw SMTP response code so you can debug at the right layer. Deliverability checklist.

Evals

Not applicable. We measure acceptance and bounce as observability, not as a model metric. The full eval set ships with the prompt and is editable. Eval format.
