Hi, we are having problem with temporary and now permanent account block with the error:
Unable to send message;Reason:550 5.4.6 Unusual sending activity detected. Please try after sometime.
We only send to around 10-12 emails addresses at a time and today we are completely unable to send any email.
Can you please lift the block from our account?
PS: the account having the issues is info@d...........al
Thanks I advance.
