I opened 2 accounts to 1 mail address
I can access both "Nstm" and "Nowkick" but i just use only "Nowkick". Both of them have the same e-mail address.
I think I deleted the "Nstm" user
I created "Nowkick" with the same e-mail address
I activated "Nstm" again.
Maybe I created Nstm to subscribe monthly for Prime. I guess you do not check whether this user was created with this e-mail address on other platforms.
If you still have any questions about these accounts I would recommend reaching out to our staff at help.twitch.tv so they can take a deeper look into this with you.
