Hi everyone, I am building a React website with Next.js, and I am trying to connect the contact form with the backend in order to receive the entered value into my emails, Do you have any advice on which email service or back-end service should I use, preferably open source or with free version usage?

Actual experimentation: I tried to connect my form with Nodemailer package, basically it's working locally but in production on Vercel's server isn't working, it doesn't allow me to receive the data to my email( Gmail) as I am receiving it in localHost, and also email.js as far as I tried isn't a good match for my contact form since it can’t send all the data, only the message value; I would really appreciate if I can get any advice or suggestions; Thanks and kind regards!
