What is Maildrop?
Maildrop lets someone choose an inbox name and receive messages without registering a conventional account.
Its GraphQL API also supports automated email tests. The same service can appear in a legitimate QA flow or in a temporary production signup.
How should you handle Maildrop signups?
Use it in your own test environment. For production recovery and rewards, request a lasting inbox and apply account-level limits.
