Yes, it is however you do have to comply with the CAN-SPAM act of 2003. This requires 3 key things:
- The email must be relevant to the audience (don't spam offerings of little blue pills).
- The sender must be identified in the email (WhoKnows takes care of this).
- There must be an unsubscribe link (WhoKnows takes care of this too).
WhoKnows ensures all our campaigns are CAN-SPAM compliant, so you don't have to worry.
