method SmtpTransport.prototype.sendMany
SmtpTransport.prototype.sendMany(
messages: Iterable<Message> | AsyncIterable<Message>,
options?: TransportOptions,
): AsyncIterable<Receipt>

This method is optimized for bulk email sending by reusing a single SMTP connection for all messages, which significantly improves performance compared to sending each message individually.

const messages = [
  { subject: 'Message 1', recipients: [{ address: 'user1@example.com' }], ... },
  { subject: 'Message 2', recipients: [{ address: 'user2@example.com' }], ... }
];

for await (const receipt of transport.sendMany(messages)) {
  if (receipt.successful) {
    console.log('Sent:', receipt.messageId);
  } else {
    console.error('Failed:', receipt.errorMessages);
  }
}

Parameters

messages: Iterable<Message> | AsyncIterable<Message>

An iterable or async iterable of messages to send.

optional
options: TransportOptions

Optional transport options including AbortSignal for cancellation.

Return Type

AsyncIterable<Receipt>

An async iterable of receipts, one for each message.
