This company has as a policy to just lock you out of your account with no communication to you. We were in the middle of an email campaign - our first mailing with this company - and all of a sudden we couldn't access our account. Mailing was stopped about 2/3rd's the way through. Our "Reputation" meter on the mailing last checked at 97%. So we were puzzled as to why were locked out. Maybe a malfunction of some sort. Nope. This is what they do when they decide you have violated their rules. They will not tell you what you did. Just lock you out. No number to call, don't respond to emails except days later when support said we violated their rules but support says they don't know what rules.
