The "best kept secret" in customer publishing has been revealed after Redhouse Lane joined the Association of Publishing Agencies (APA).

The membership to the APA, the representative body for the £900 million customer publishing industry, is the first in Redhouse Lane's history.

David McNamara, Head of Publishing and Digital, says he is pleased to see Redhouse Lane contributing to the growth of the customer publishing as well as being recognised among the best in the business.

"Although we've had longstanding relationships with our clients over the past three decades, we've also had something of a reputation for being the 'best-kept secret' in the industry," he says.

"We'd like more people to discover how our award-winning magazines, films and websites consistently deliver results for our clients. The membership to the APA puts us at centre stage."

The APA is widely acknowledged as the standard bearer for customer publishing in print and online. Formed in 1993, the group of agency professionals commission research, launch and develop high profile initiatives and organise a number of industry awards.

The association currently has more than 70 representatives, including affiliate members and overseas members.
