Hi @Qlipoth
I am not an expert on Next.js but today I tried to set up a small app via generator and this app has successfully sent an email.
Could you provide a code snippet where I will be able to see how you use SDK?
It would be awesome if you could make some test app that reproduces an issue but if not code snippet is also fine.

Hello. I refused using this package in favor of an older version of it: mailgun-js and it works properly. I created file: pages -> api -> mail.js My code snippet:

const { MAILGUN_API_KEY, MAILGUN_DOMAIN, MAILGUN_URL, FROM_EMAIL_ADDRESS, CONTACT_TO_EMAIL_ADDRESS } = process.env;
const mailgun = require('mailgun-js')({ apiKey: MAILGUN_API_KEY, domain: MAILGUN_DOMAIN, url: MAILGUN_URL });
export default async function testMail(req, res) {
try {
const { email, description, name } = req.body;
const mailgunData = {
from: FROM_EMAIL_ADDRESS,
to: CONTACT_TO_EMAIL_ADDRESS,
subject: 'new message from ${email}',
text: ${name}: ${description || "description"},
};
await mailgun.messages().send(mailgunData);
res.status(200).json({ status: 'Ok' });
} catch (err) {
console.error(err);
}
}

Of course, it is your choice, but I would not recommend you to use mailgun-js package.
It is deprecated and has security vulnerabilities.

I am closing this issue.
Feel free to create a new one if you decide to use mailgun.js and will have an issue.
