Is Nodemailer a free api/library? If it is not free, where can I see the price. How is it different from the free version?
I am looking for (free) library or api to send email (company (not gmail) to customer)
Its an opensource library with MIT license.
There is no paid version for this library - but you can donate. May be you should use the library and donate for what it gives you.
The donate button is located at the bottom left corner -
