Three mailers have been sent out to 6,000 industry professionals, highlighting the three tiers of D&AD membership -- Full, Associate and New Blood.
The drive through Leonardo, the digital and direct arm of Leo Burnett, reminds winners of D&AD's "yellow pencil" awards that they are eligible to become members.
The D&AD receives more than 18,000 entrants to its awards each year. Those who win are automatically entered into the D&AD's prestigious creative directory, known simply as "the book".
Marcelle Johnson of D&AD said: "Those eligible for full membership will be aware of the prestige attached with making the book. It's a huge achievement and something to be proud of among one's peers. For most, though, it stops there and those who have been associated with winning work, like clients and account handlers, often don't realise that they are also eligible."
As part of its anniversary celebrations, D&AD is also offering veterans, whose subscriptions have lapsed, the opportunity to rejoin.
