Frequently looked up
- Q1How do I check if an email is temporary or disposable?
- Paste the address into Reloop's free temp email checker. It parses RFC syntax, matches the domain against a ~210,000-provider disposable catalogue including Mailinator, Yopmail, and Temp-Mail, flags role prefixes, and looks up MX records. A disposable verdict means the domain is a known throwaway provider without probing the mailbox.
- Q2Why should you block disposable email addresses?
- Disposable addresses stop existing and once the mailbox expires, messages sent to them hard-bounce. Mailbox providers read sustained bounce rates as a sign of sending to bad lists, causing reputation damage that applies to your whole domain, not just throwaway recipients.
- Q3What does a clear verdict mean?
- A clear verdict means the address parsed correctly, the domain is not on the disposable list, and it is not a shared role prefix. If MX records were found, mail can theoretically be routed to that domain, but this is not proof of delivery.
- Q4How accurate is the disposable email check?
- Disposable matching is a list lookup where the domain is either on the catalogue or it isn't. New temp-mail providers appear constantly, so a clear result means 'not currently known to be disposable' but is not a guarantee.
- Q5What is the difference between the free temp email checker and free email validator?
- The temp email checker is focused on disposable and throwaway detection at signup time with a single address, public API, and no key. The free email validator adds bulk CSV cleaning, fuller health scoring, and list export for campaign hygiene.
