Ethereal Email VS Smtp4dev

EtherealMail - Ethereal is a fake SMTP service, mainly aimed at Nodemailer and EmailEngine users (but not limited to). It's an entirely free anti-transactional email service where messages never get delivered. - Source: dev.to / 3 months ago

Since this is node subreddit, I would suggest you use nodemailer. You can create a free account on https://ethereal.email to test with, then when you are ready to go, sign up with whichever transactional mail service you choose (there will likely be a nodemailer extension for it, or it will just print vide SMTP creds to add to nodemailer) and update the config in your app. Source: 10 months ago

Almost positive the path to the file is correct. I tried with the code you see in the link and also tried specifying the absolute path and neither worked. I tried in mailtrap and I also tried with ethereal.email. Source: about 2 years ago

If you want to see the messages being caught, then instead of creating a test account in the function, go to Ethereal and click Create Ethereal Account. Then plug the username and password in. You can then visit the inbox for that account and see everything that was caught. - Source: dev.to / almost 3 years ago

Be sure to grab the config from your test email account, or use: https://ethereal.email. - Source: dev.to / almost 3 years ago

Depends on the infrastructre setup, but if you're able to specify smtp server the backend will use you can you something like https://github.com/mailhog/MailHog or https://github.com/rnwood/smtp4dev to catch any sent email, regardless of email address and read it via the respective api. Both mailhog and smtp4dev have decent api documentation. Source: about 1 year ago

If so you could check out smtp4dev, it gives you a locally hosted client that you can use to intercept any mail send out by your app and displays them in a nice web based gui interface so can see what they look like. Source: almost 2 years ago
