Frequently Asked Questions
What is a disposable email address?
A disposable (or temporary) email address is created for short-term use, often to sign up for something without revealing a real address. Providers like Mailinator and 10MinuteMail auto-delete inboxes after a short time.
Why should I block disposable emails?
Disposable emails are commonly used for fraud, spam sign-ups, trial abuse, and fake reviews. Blocking them at signup improves data quality and reduces abuse.
How often is the disposable domain list updated?
RocketVerifier maintains a list of 60,000+ disposable domains that is automatically refreshed from community-maintained sources, so new disposable providers are caught quickly.
Can I block disposable emails automatically on my signup form?
Yes — RocketShield is an embeddable widget that blocks disposable, invalid, and role-based emails at your signup or checkout form in real time, before submission.
