Disposable email database
Is emailondeck.com a disposable email?
Quick answer
emailondeck.com is operated by EmailOnDeck, 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 EmailOnDeck
EmailOnDeck issues disposable email addresses through a two-step CAPTCHA process. The two-step gate makes it slightly harder to script than fully no-signup disposables, but the addresses are still throwaway.
What it’s typically used for
Signups where the user wants a small but real barrier between themselves and follow-up email — often used for crypto-related or anonymous account creation.
Should you block emailondeck.com in your signup form?
EmailOnDeck addresses are designed to be temporary by definition. Block at signup.
How to detect emailondeck.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:
curl -X POST https://api.vouchley.getrevlio.com/v1/verify \
-H "Authorization: Bearer vch_live_..." \
-H "Content-Type: application/json" \
-d '{
"email": "anyone@emailondeck.com",
"ip_address": "203.0.113.10"
}'
# Response:

# "score": 12,
# "recommendation": "block",
# "email": { "disposable": true, "valid": true },

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