Nodemailer is the most popular email sending library for Node.js, supporting SMTP, Sendmail, Amazon SES, and custom transports. It handles MIME construction, attachments, HTML/plain-text multipart messages, TLS/STARTTLS, DKIM signing, and OAuth2 authentication with zero runtime dependencies.
Use cases
- send emails from node.js
- send transactional email via smtp
- send html email with attachments in node
- sign outgoing email with dkim
- send email through amazon ses from node
- send email with oauth2 gmail authentication
- test email sending locally
When to choose
- you need to send email from a Node.js application or server
- you want a dependency-free, well-maintained email library with SMTP, SES, and Sendmail support
- you need DKIM signing, OAuth2, or proxy support for enterprise email delivery
When to avoid
- you need to receive or read incoming email rather than send it
- you are not using Node.js
- you want a full hosted email API service rather than a library
