By definition, email spam is any email that meets the following three criteria:

Internationally, it is a requirement that every sender must include a single-click unsubscribe link that instantly removes the subscriber from your list. Once they unsubscribe, you can never email them again.
We reserve the right to suspend your account immediately and start investigating your activity if your campaigns have high percentage of spam complaints, bounces, unsubscribes or very small open rate. If it turns out that you were sending emails without permission - we will suspend your account. We can ask you to prove that you have permission from your recipients and we can close your account if you do not have such proof. Otherwise, we will activate your account and you will be able to use the service again.
Creating multiple accounts with overlapping uses (similar email content, same links or same FROM email) or in order to evade the permanent suspension of a separate account is strictly forbidden.
