Email Validator

Straightforward email validation that checks syntax, DNS records, and filters out disposable addresses. Use it before sending campaigns or to clean up signup lists. Includes a batch processor for CSV files, which is the real value here since validating one-off emails is easy enough without a tool. Built on email-validator and dnspython, so you're getting proper RFC compliance checking and MX record verification. The disposable email detection will catch the obvious throwaway domains. Nothing fancy, but if you're running email campaigns and dealing with bounce rates, this handles the tedious validation work you'd otherwise script yourself.
