What is Spam?
In terms of unwanted email, Spam can only be defined as such if it is both unsolicited and bulk.
According to spamhaus.org:
Unsolicited means that the Recipient has not granted verifiable permission for the message to be sent.
Bulk means that the message is sent as part of a larger collection of messages, all having substantively identical content.
We get unsolicited email all the time from people legitimately trying to contact us without us necessarily knowing who the sender is. This is completely fine.
We also receive bulk email in the form of subscribed services which too, is also fine.
While we all hate the flood of emails urging us to purchase pharmaceutical goods, spam isn’t an issue of content but rather of consent. If your personal identity and context is irrelevant because the message could be equally be applicable to anyone else and you haven’t granted explicit permission then the message can be deemed as spam.
