Marketers should identify envelopes containing marketing material, according to the Advertising Standards Authority (ASA). The ASA ruled against Virgin Media when the telecoms giant broke advertising rules because an envelope it sent out as part of a mailshot did not clearly identify the contents as marketing material. The ASA said the mailshot broke the CAP Code clause 22.1, which states that "marketers, publishers and other owners of media should ensure marketing communications are designed and presented in such a way that it is clear they are marketing communications".
