Frequently Asked Questions
Is Ethereal Email good for automated testing?
For local manual testing during development, yes. For CI/CD automation, no — Ethereal lacks a REST API for creating inboxes programmatically and retrieving emails in test code.
What's better for test automation, MailCatch or Ethereal?
MailCatch. It provides a REST API for creating inboxes, receiving emails, and extracting OTP codes — all designed for CI/CD pipelines. Ethereal is better for manual email inspection during development.
Is Ethereal Email really free?
Yes, completely free with no limits. MailCatch also has a free tier (50 inboxes/month), but adds a full REST API, OTP extraction, and CI/CD integration that Ethereal doesn't offer.
Can I use Ethereal Email in CI/CD pipelines?
It's technically possible but cumbersome. You'd need to create accounts via Nodemailer and parse emails manually. MailCatch is purpose-built for CI/CD with long polling and auto OTP extraction.
