This seems to just generate a random string to go with whatever domain I have set. Personally I prefer my email aliases to be of the form `<business_name>@<my_domain>` or `<website_domain>@<my_domain>`. That way if you do start getting unsolicited email it is crystal clear who is spamming you (or has sold/leaked your data).
In fact, given it seems to just put a random string in front of a domain name you give it I'm a little curious as to why they need your API key at all - is it just to ensure that you are not creating duplicate email aliases?
