From 1st October 2020 we will no longer accept email addresses to check.

Even requests that had a leading @-symbol like /check/@example.com have not been accepted by our API. Since it is not a certain email address we now remove that @-symbol for you and only check the domain.


When we launched the API we wanted to make it as simple as possible for you guys to use it. That is why we have added support for email addresses. Even though we have always stripped them to the domain part and only checked this against our database. But all the requests which we receive to the API are being saved in our server logfile. We use it for debugging only.

To enhance privacy here a little bit more, we have decided to only allow domains in API calls starting from 1st October 2020. API calls with an email address will then be answered with an error message. Please update your application so it still works with our API.

Below you can find our examples how to use the API in PHP. We have added a check for email addresses there which makes only use of the domain part.
