What Email address is not blacklisted?

Hi, Trying to sign up as I’m looking to develop a program to gather data for some tokens.

When I try to sign up with my outlook.com email address it returns black listed ?

What email providers aren’t black listed? or can it be whitelisted?

Kind regards

Yes, when we receive too may spam signups with a domain we blacklist it for a while. Please email support.bitquery.io, we will enable access for you.
