Disposable email database
Is mailinator.com a disposable email?
Quick answer
mailinator.com is operated by Mailinator, a disposable / temporary email service. Signups using this domain are almost always throwaway. Block at signup if your product depends on long-term email reachability.
About Mailinator
Mailinator is one of the oldest and most widely used disposable email services. Anyone can read mail sent to any Mailinator address by simply visiting the public inbox at mailinator.com — no signup, no password, no privacy.
Operating since 2003.
What it’s typically used for
Throwaway accounts on signup forms, one-time email confirmations the user never wants to access again, or testing email flows during development.
Other domains operated by Mailinator
The same service runs additional alias domains. Block these alongside the main domain — otherwise users will simply switch to an alias to bypass your filter.
- binkmail.com
- bobmail.info
- chammy.info
- mailtothis.com
Should you block mailinator.com in your signup form?
A user signing up with a Mailinator address has no intention of receiving ongoing communication. Block at the signup layer to protect deliverability and prevent free-tier abuse.
How to detect mailinator.com in code
You don’t need to maintain a hand-rolled list. Vouchley returns a disposable flag (and the rest of the signup score) on every check:

-H "Authorization: Bearer vch_live_..." \
-H "Content-Type: application/json" \
-d '{
"email": "anyone@mailinator.com",
"ip_address": "203.0.113.10"
}'
# Response:

Vouchley keeps the disposable list current — including alias domains and new providers — so you never have to maintain it yourself.
