What is spam?
"Spam" is email that is both unsolicited and in bulk. Unsolicited means that the recipient has not granted permission for the message to be sent. Bulk means that the same message has been sent to many people usually all at once.
An email that is unsolicited but not sent in bulk is fine, such as asking about a product before buying it. An email that is sent in bulk but not unsolicited is fine, such as sending a newsletter. But sending an email that is both unsolicited and in bulk is spamming.
Dynadot does not allow its services to be used for the transmission of spam. See our spam policy for more info.
