What is the name of all pro domain offer by addy.io (email alias)?

Probably gonna get some hate for this. But I’m sure a company or a nation state could afford to sign up and spend €4, then clear this as a business expense to get this information. This would be far cheaper than paying someone for their time and energy, as opposed to doing a clandestine infiltration of the forum, to ask for such information. Sadly OP I’m not a subscriber to them so I honestly can not answer your question. Have you tried reaching out to them at contact@help.addy.io see if they will advice you?
