Answered Old accounts/e-mail deleted

[Redfe]

Is there a way to Discover old usernames from a deleted e-mail account?

I forgot my old account and my e-mail was deleted 😔

If you no longer have access to the email address then no, unfortunately there is no way to get a list of the Pokémon Vortex accounts associated with said email account as there is no proof they belong to you, we do not give that information out.

This self-use tool is how you get a list of accounts associated with an email address but as stated, you need access to the email address to retrieve the email it sends.
