It’s been challenging, but we have now emailed every address we could reach through our store and newsletter systems. The emails have been going out in batches since Friday. If you received one, we want to confirm that it is legitimately from Coinkite.

Please treat this as urgent. Follow the advisory for your model, upgrade your device, generate a new seed, and carefully move your funds. Help spread the word, especially to people who are less online and may not see this update.
