Nodemailer report card

Best for sending email from Node.js code
Nodemailer is a free module for sending email from Node.js, with no dependencies. It's a code library, not a service, so you bring the mail server and it adds no deliverability tools or analytics.
Who Nodemailer is for
- Fits if you write Node.js and want to send mail from your own code
- Works for apps that already have an SMTP server and need a way to talk to it
Who Nodemailer is not for
- Skip it if you don't write code, since it's a library with no screen
- Too light for deliverability, tracking or analytics, none of which it includes
- Not for you if you're on an older Node.js: version 10 needs Node.js 20 or later
- Watch out: you supply the SMTP server or other transport yourself
Why Nodemailer gets a 2.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree under the MIT-0 license, including for commercial use. Anyone can download it, so it earns the top mark.
- AFree plan and trialEverything is free with no limits, no account and no trial to run out.
- CFeaturesSends over SMTP, Sendmail, SES or streams, with attachments, DKIM, OAuth2 and test accounts. It does that job fully, but it's a small job: no analytics, no deliverability tools.
- DEase of useNo store rating on record. It's a code library, so you write the code and supply the transport.
- CPlatforms and integrationsA Node.js library only, with Amazon SES and Ethereal listed. No app, no dashboard.

Keep Nodemailer, or make your own?
Keep it
Nodemailer is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.6 is higher than 34 of the 50 other email sending services we grade.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, Amazon SES and Ethereal among them, and has an API.
What this rests on. Nodemailer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Nodemailer?
Nodemailer is a free module for sending email from Node.js applications, with no runtime dependencies. It sends over SMTP, Sendmail, Amazon SES or streams, and supports attachments, HTML and plain-text bodies, DKIM signing and OAuth2. It is a code library, not a hosted sending service.
Worth knowing
- It is a library only: you supply the SMTP server or other transport, and it adds no deliverability tooling or analytics.
- Nodemailer 10 requires Node.js 20 or later; older Node.js versions stay on the 9.x line.
- The site says development is sustained by EmailEngine licenses, and the library itself is MIT-0 licensed.
Key features
- Zero runtime dependencies
- Installs with npm install nodemailer and includes TypeScript definitions, with both ES module and CommonJS builds.
- Multiple transports
- Sends through SMTP, Sendmail, Amazon SES or streams, using a reusable transporter object.
- Messages and attachments
- Builds multipart messages from HTML and plain-text bodies, with attachments, embedded images and full Unicode support.
- Security options
- TLS and STARTTLS are handled automatically, and DKIM signing, OAuth2 authentication and proxy support are included.
- Test accounts
- Integrates with Ethereal, a fake SMTP service, to generate test accounts for local development.
