CloudMail Limits For Outgoing Email Messages

CloudMail is not intended for sending bulk or automated mail. Because of this, it has a limit on the number of outgoing messages. This protects the service from being listed on any public blacklists. If you have reached the limit, it is because you have sent more emails than the service settings allows or your mailbox has been hacked and is being abused to send spam. If you are not sure why you reached the limit, please contact our technical support.

If you have a Managed Server from our company, send emails from your applications exclusively using the "localhost" SMTP server, not using the CloudMail service.
