There is an hourly limit of 200 outgoing emails per domain. If you send this amount within any hour, most emails will bounce back with an undeliverable error. In this case, it will take some time for your account to resend, so we recommend waiting at least 1 hour after this issue occurs before you start sending emails again.
Sending any unsolicited email will result in suspension or termination of the offending account. We take a zero-tolerance stance against the sending of spam and other forms of spam.
Also, mass mailing is prohibited.
