Disposable email database
Is simplelogin.io a disposable email?
Quick answer
simplelogin.io is operated by SimpleLogin, 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 SimpleLogin
SimpleLogin (acquired by Proton in 2022) is an email-aliasing service that lets users create unlimited per-service aliases forwarding to a real inbox. Acquired and maintained as part of the Proton privacy suite.
What it’s typically used for
Privacy-aware users who want a separate alias per signup. Common among Proton Mail users and the broader privacy-first audience.
Other domains operated by SimpleLogin
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.

Should you block simplelogin.io in your signup form?
Like AnonAddy, SimpleLogin users are real people with real intent. Risk-tier rather than hard-block — these accounts often convert well in B2B SaaS.
How to detect simplelogin.io 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@simplelogin.io",
"ip_address": "203.0.113.10"
}'
# Response:
# {
# "score": 12,
# "recommendation": "block",
# "email": { "disposable": true, "valid": true },
# ...
# }Block disposable signups in one API call.
Vouchley keeps the disposable list current — including alias domains and new providers — so you never have to maintain it yourself.
