I’ve been getting postcards from Emiliano Granado for a few years at this point, and he’s been sending them to photo industry folks since 2008.
I’ve saved quite a few of them, put one or two up on the wall, etc. They are straightforward, have included a variety of subjects, and on the back Granado always includes a handwritten hello. He tells me his mailing list is over 1000 strong, many of them paid subscribers, who part with $10 a year for 6-10 cards.
Just goes to show that promos don’t have to be elaborate to be effective.
(In case you’re inclined to send me anything, please note the above address is outdated.)
