Oi Julio.
Tudo bem?
It could be an error, having flagged your account as Spam (please check this thread Customers do not receive answer sent by agents from freshdesk | Freshworks Community ).
You should proceed as suggested: Write to support to that email account.
You may also chat with someone from support:
Support : Freshdesk
In either way or scenario, they should be able to unblock your account.
You may check this:
Blocked outgoing emails | Freshworks Community
I noticed you have already checked this:
Why outgoing emails are blocked for my account ? | Freshworks Community
In all, the suggestion is to contact Support. Here is more like a Community Forum.
I’m also pinging some colleagues from FW: @Keer @hemanth.ramya @jim.stephen @alyssia.correa
Hope this helps.
Regards,
