Hi <<First Name>>
For most of my art sales, I make a personal donation of 10% on your behalf to a wildlife organization (after commissions and GST, but before costs). I do this once a year after doing my taxes - it's my reward for getting them done because only then do I find out which bird raised the most for conservation! And for FY 2020 its (insert drum roll and fanfare) "Portrait of a tūī", closely followed by "I shall ride every storm".
The tūī really is NZ's most beloved bird!
