We are trying to send e-mails from domain services333.000webhostapp.com
All of those e-mails go in junk.
From smtp provider said
‘Your domain is blacklisted, this is why emails arrive in junk’

QUESTION is
How to unblock it - because it is UNUSED and NEW domain and site and -
How can they list domain and site that was just created and NOT used?
