I had a similar issue, with the only difference that I did not send any bulk emails at all! I have no idea what caused Hubspot to block my account.
I have a free account as a trial of Hubspot, and I like the service - although I really loath the way this email block was performed and subsequently handled.
Regarding your option A. Are you saying that if I upgrade to a paid plan, this permanent block can be stopped? I would consider that if that’s the case
