Pick who they are and how you want it to sound. You get three lines to copy, and one question to hide in it so the card feels like it could only be from you.
“All the best” is what people write when the box is blank and the meeting is starting. Two lines about one real thing, plus a question only someone who worked with them would get right, is what they remember.
That is exactly what Outro Party is built on: everyone types two lines and one question, and we turn it into a ten-minute game show starring them on their last day, with a film of it all to keep.
One payment, no accounts for the people writing, money back until it is delivered.
Name one real thing: something they did for you, a habit everyone knows, or a moment you shared. Then wish them well. Two lines about something specific land harder than a long general message.
Keep it short and kind: say you wish you had worked together more, mention one thing others say about them, and wish them luck. Nobody expects a speech.
Ask everyone for two lines and one question only people who worked with them would get right. Outro Party turns those into a ten-minute game show they play on their last day, with a film to keep.
