Responding here in case anyone else encounters this! The __dirname
above was really helpful, but this is my code to actually see the image embedded in the email
My img tag:
<img src="https://stackoverflow.com/questions/48449379/cid:logo">
My attachments snippet:
attachments: [{
filename: 'Logo.png',
path: __dirname +'/folder/Logo.png',
cid: 'logo' //my mistake was putting "cid:logo@cid" here!
}]
