What is a disposable email?

Originally created to protect users from spam, disposable emails have now become a source of sign-up abuse for software platforms, SaaS products, and email list-building campaigns. A disposable email is a temporary address meant for short-term use and then discarded. These emails are often used to avoid revealing the user’s real identity during one-time registrations. They’re frequently exploited by free riders who sign up multiple times using different disposable addresses to repeatedly access free trials, credits, or features—benefits intended for legitimate, first-time users.

Why should I detect disposable emails?

Detecting disposable emails protects your SaaS platform from abuse and helps maintain the integrity of your email list. By filtering out temporary and fake sign-ups, you prevent free riders from repeatedly exploiting your free trials, credits, or features intended for first-time testers. It also improves the quality of your user data, reduces bounce rates, and protects your sender reputation and improves your engagement rate from your email marketing efforts. Minelead's disposable email detection API is perfect to detect and block fake sign-ups in realtime with a high accuracy.

How accurate is Minelead's disposable email detection?

Minelead's disposable email detector maintains a 99.8% accuracy rate by combining a constantly updated database of over 10,000 known disposable domains with advanced pattern recognition and machine learning algorithms to detect new and emerging temporary email services.

How does Minelead disposable email detector work?

Minelead's disposable detection system works through multiple layers: 1) Domain matching against our comprehensive database of known disposable providers, 2) Pattern analysis to identify suspicious email formats, 3) Domain reputation scoring and age verification, and 4) Mail server fingerprint analysis which analyzes the characteristics of servers used by disposable email providers to detect new and emerging disposable domains and services in real time.

What are common disposable email providers?

Common disposable email providers include services like 10MinuteMail, Guerrilla Mail, Mailinator, TempMail, ThrowAwayMail, and hundreds of others. Our database is constantly updated to include new disposable email services as they emerge.

Can disposable emails affect my email deliverability?

Yes, disposable emails can significantly impact your email deliverability. Since these addresses are temporary and often discarded after use, they tend to increase bounce rates and lower engagement, two key factors that can damage your sender reputation with email service providers.
