SMTP settings

Copy the exact values from your in-app Settings page. Most accounts use these defaults.

Email plugin

Use the Nodemailer provider with Parcel Wing's SMTP host and your API key.

// config/plugins.js
module.exports = ({ env }) => ({
  email: {
    config: {
      provider: "nodemailer",
      providerOptions: {
        host: "smtp.parcelwing.com",
        port: 587,
        secure: false,
        auth: {
          user: "parcelwing",
          pass: env("PARCELWING_API_KEY"),
        },
      },
      settings: {
        defaultFrom: "Acme <[email protected]>",
        defaultReplyTo: "[email protected]",
      },
    },
  },
});

Use a verified sender

Your from address should belong to a sending domain that is verified in Parcel Wing. This keeps SPF, DKIM, and DMARC aligned for better deliverability.

Troubleshooting

• Use port 587 with STARTTLS, not implicit TLS on port 465.
• Use parcelwing as the username and an active Parcel Wing API key as the password.
• Make sure the sender address uses a verified sending domain.
• If a vendor has a test email button, send a test before enabling production email.
