Advertising Lists of Businesses / Products / Attendees or list brokerage email

We do not permit outbound B2B, B2C emails advertising lists for sale. 

The practice of selling, buying or sending to lists of purchased email addresses – whether business to business (B2B), business to consumers (B2C) or other categories, is in direct violation of M3AAWG core values. There are many reasons why buying and selling of email address lists is an abusive practice. It leads to a high volume of non-permission based email and creates a drain on corporate resources.
