Can we deliver bulk email using single connection?

Can we deliver bulk email using single connection? Like in nodemailer there's an option for pool

[zackschuster]

not with a simple toggle, but we do FIFO queueing on repeated calls to send/sendAsync & after the queue is empty we leave the connection open for one second in case a new message comes in.

this should be enough to allow you to trivially implement some brand of pooling using promises & for-of loops, but you can let me know if you encounter difficulties doing so 😄

Are there any docs for that? It'll be helpful for me.

it's more of a snippet kind of thing:

import { Message, SMTPClient } from 'emailjs';

const client = new SMTPClient({ /* your configuration */ });
const messages: Message[] = [ /* your messages */ ];

// to queue one at a time:
for (const message of messages) {
	const response = await client.sendAsync(message);
}
// --- OR ---
// to queue all at once:
const responses = await Promise.allSettled(messages.map(message => client.sendAsync(message)));

Are you sure by using this method all messages will be sent in one connection?

as long as less than one second passes between calls to send/sendAsync, it should re-use the same connection.

Ohhkay will check it out. Thanks alot!
