Disify
Email Services · Data Validation
Disify is a free disposable and temporary email detection API that identifies throwaway email addresses used to bypass registration systems. The Disify API checks whether a submitted email address belongs to a known disposable email provider (such as Mailinator, Guerrilla Mail, or 10minutemail) and returns a simple verdict.
User registration forms, free trial signup pages, and email list hygiene tools that need to block disposable or temporary email addresses
Disposable email detection via blacklist lookup — checks domain against known disposable email provider list. No API key or registration required. Completely free. Blacklist updated regularly but lags new disposable domains by days/weeks. Known limitation: Cannot detect custom disposable domains or single-use email services. Best used as first-pass filter; combine with SMTP validation (EVA) for comprehensive coverage. Recommendation: Use both Disify + EVA for reliable email validation.
