After looking into the docs for Nodemailer, I couldn't find anything about unsubscribing to an email.
I am trying to create a Newsletter for my web-app, and I don't want to use emailing services such as Mailchimp or any other due to the fact they are not free forever.
Do you have any ideas on what I should do?
Help will be very appreciated!
My other js file which initialises transporter. Sharing this for sake of completeness.
