Built for clean integrations

A small API that does one thing well.

Pro users can create inboxes, fetch messages, and inspect usage through authenticated endpoints. Every request is rate limited and recorded.

curl -X POST https://your-domain.com/api/v1/email/create \
  -H "Authorization: Bearer YOUR_NULLMAIL_API_KEY"

{
  "data": {
    "email": "test@web-library.net"
  }
}
Questions, answered

Temporary email, made clear.

What is NullMail for?+

Privacy-conscious testing, prototype validation, and receiving low-risk temporary messages. It is not intended for spam, ban evasion, bulk account creation, or abuse.

Does Pro include sending email?+

No. NullMail is intentionally receive-only. Pro provides API access to the same temporary inbox flow.

Can the email domain change?+

Yes. Administrators can add, enable, disable, and select domains. New inboxes use the active domain immediately; existing inboxes keep their original domain.

Is payment live?+

The subscription data model and checkout boundary are ready, but a real payment provider and verified webhook must be connected before production purchases are enabled.
