 FAQ

What makes an email address RFC 5321 compliant?

RFC 5321 defines the format for email addresses used in SMTP. A compliant address has a local part (before the @) containing alphanumeric characters, dots, underscores, and hyphens, followed by the @ symbol and a valid domain name with at least one dot separating the domain labels.
Why do developers need fake email addresses for testing?

Using real email addresses in development and testing environments risks accidentally sending emails to real people, violating privacy regulations like GDPR, and exposing personal data in logs or databases. Fake addresses avoid these issues while still providing realistic data for form validation and database testing.
What is the difference between a fake email and a disposable email?

A fake email address is a randomly generated string that looks like a real address but does not correspond to any actual mailbox. A disposable email is a temporary but real address that can receive mail for a short time. Fake emails are for testing and development, while disposable emails are for one-time signups and spam prevention.
