Disposable Email
A temporary email address created for one-time use, often to avoid giving out a real email address.
Disposable emails (also called throwaway or temporary emails) are created using services like Mailinator, Guerrilla Mail, 10MinuteMail, and Temp-Mail. They typically self-destruct after a set period (10 minutes to 24 hours).
Why they're a problem:
- They inflate your subscriber count with fake signups
- They never engage with your emails (hurting engagement metrics)
- They can be used for abuse (free trial exploitation, spam registration)
- They waste verification credits if not caught early
How to detect them: SendSure maintains a database of 10,000+ known disposable email domains that is updated regularly. Our verification engine flags disposable emails at stage 5 of the 27-stage process, before any SMTP checks are performed (saving credits).
Best practice: Block disposable emails at the point of entry (signup forms) using SendSure's form widget or real-time API.
