SMTP

Send through SMTP when your app or tool cannot call the API. Each message goes through the same checks, limits and logs as POST /v1/emails.

Connection Settings

import nodemailer from 'nodemailer';

const transport = nodemailer.createTransport({
  host: 'smtp.inboxjot.com',
  port: 465,
  secure: true,
  auth: { user: 'inboxjot', pass: process.env.INBOXJOT_API_KEY },
});

await transport.sendMail({
  from: 'Acme <hello@send.acme.dev>',
  to: 'riti@example.com',
  subject: 'Your receipt from Acme',
  html: '<p>Thanks for your order.</p>',
});

Developers › SMTP in the dashboard shows the same values. Create the key in API Keys.

How Messages Map

• To and Cc keep the header addresses that are also envelope recipients. Every other envelope recipient becomes Bcc.
• The From header sets the sender. Without it, the MAIL FROM address is used.
• Reply-To, the subject, the HTML and text parts and attachments carry over.
• X- headers pass through, except a few that Inboxjot reserves for delivery. In-Reply-To, References and the List-Unsubscribe headers also pass through.
• Open and click tracking follow the settings of the sending domain.
• Logs show SMTP as the source of the email.

Limits and Replies

A queued message gets 250 2.0.0 Queued as and the email id. A rate limit gets a temporary 451 reply, so your client retries later. An auth or permission problem gets 550, and an invalid message gets 554.
