This is simple library (no dependencies) to generate HTML-only email messages (without attachments) from given parameters. Supports Unicode for names and subject, but encodes only when it's actually required:
const { simpleHtmlEmail } = require('mailbuilder');
const testMsg = {
from: { name: 'John "Cool" Doe', address: 'john@doe.com' },
to: [{ name: 'Вася Пупкин', address: 'vasya@pupkin.com' }],
bcc: [
{ name: 'One Spy', address: 'spy@kremlin.ru' },
{ name: 'Big Eye', address: 'fbi@whitehouse.org' },
],
subject: 'Some 💄 subject',
html: `This is our <b>html</b> message content
It's also <i>multiline</i> just in case`,
};
const res = simpleHtmlEmail(testMsg);
/**
