MailChecker is a cross-language library for validating email format and detecting temporary/disposable email addresses, backed by a database of over 55,000 throwaway email domains. It is available for Node.js, Python, PHP, Ruby, Rust, Go, and more.
Use cases
- block disposable email signups
- detect throwaway email addresses
- validate email format on registration forms
- filter temporary mailboxes like yopmail
- prevent spam signups with fake emails
- check if an email domain is a temp mail provider
When to choose
- you need disposable email detection across multiple programming languages
- you want a large, actively maintained list of throwaway domains
- you need both email format validation and temp-mail blocking in one library
When to avoid
- you need full email deliverability verification (SMTP checks)
- you only need syntax validation without disposable detection
- you need real-time mailbox existence checks
