Question 1

How do I send an HTML email with embedded images using emailjs?

Use the Message class to create attachments with Content-ID headers, as shown in the example where images are embedded in HTML using cid references, and set alternative or inline options for proper rendering.

Question 2

emailjs vs nodemailer: which is better for Node.js?

Accepted Answer

emailjs is simpler with built-in TypeScript support and greylisting handling, while nodemailer has a larger ecosystem and more plugins. Choose emailjs for straightforward SMTP sending with TypeScript, or nodemailer for advanced features like streaming and broader community support.

Accepted Answer

Yes, it supports XOAUTH2 authentication, which can be used with Gmail by providing application-specific passwords or OAuth tokens, as mentioned in the authentication methods.

Question 4

How to handle errors when sending emails with emailjs?

Accepted Answer

Use the promise-based sendAsync method with try-catch blocks, as demonstrated in the examples, to catch and log errors, but note that error handling is basic and may require custom retry logic for robustness.

Can I use emailjs in a serverless function like AWS Lambda?

It supports common ports like 25 for unencrypted, 465 for SSL, and 587 for TLS, with defaults based on the ssl and tls options, as detailed in the API reference for SMTPClient.
