The Evolution of Mailinator
At the most basic level, Mailinator was built to provide infinite (for conversation’s sake) mailboxes at a given domain.
The original use case was to create a “throw-away” email address so that users could avoid having inboxes that were used just for signing up for various web services.
But over time, this utility became useful for programmers who needed to validate that their workflows delivered the emails as intended.
Gradually, feature requests shaped other functionality that this core user group wanted to make automating processes easier.
Today, Mailinator is the predominant resource for world-class QA testing teams looking to automate their email and sms workflow testing.
