Email bot

How it Works

In this post I’m just going to show you something cool I made using cloudflare workers.

import { EmailMessage } from 'cloudflare:email';
import { createMimeMessage } from 'mimetext';

export default {
	async email(message, env, ctx) {
		const content = await new Response(message.raw).text();
		const messages = [
			{ role: 'system', content: 'you are an email responder, reply to the given message' },
			{ role: 'user', content }
		];
		// @ts-expect-error broken bindings
		const { response } = await env.AI.run('@cf/meta/llama-3.2-11b-vision-instruct', { messages });
		const msg = createMimeMessage();
		msg.setHeader('In-Reply-To', message.headers.get('Message-ID') as string);
		msg.setSender({ name: 'Sean Behan', addr: '[email protected]' });
		msg.setRecipient(message.from);
		msg.setSubject('RE');
		msg.addMessage({
			contentType: 'text/plain',
			data: `${response}\n\nThis was an automated message. If this is urgent, message Sean on Telegram https://t.me/codebam`
		});

		const replyMessage = new EmailMessage('[email protected]', message.from, msg.asRaw());

		await message.reply(replyMessage);
		await message.forward('[email protected]');
	}
} satisfies ExportedHandler<Env>;

This small amount of code is all it takes to automatically reply to all my emails with llama3.2!

Feel free to copy it and use it yourself. The source code is on GitHub.
