The instructions your model reads when the skill loads.
Add <Api.Mailer.Smtp ... /> to your webiny.config.tsx to configure SMTP email delivery at build time. The component serializes the settings into the build artifact — always pass the password via an environment variable, never hard-code it. Deploy the API after making changes.
import { Api } from "webiny/extensions";
<Api.Mailer.Smtp
host={"smtp.example.com"}
port={587}
user={"smtp-user"}
password={process.env.SMTP_PASSWORD!}
from={"[email protected]"}
replyTo={"[email protected]"} {/* optional */}
/>
Place this inside the JSX returned by your config component in webiny.config.tsx, alongside other <Api.*> extensions.
| Prop | Type | Required | Description |
|---|---|---|---|

user | string | Yes | SMTP authentication username |
password | string | Yes | SMTP authentication password — use env var |
from | string | Yes | Default sender address |
