When you want to send a nice message to someone, maybe for a birthday, thank you, or get well soon, you might use one of those ecard apps. There are some great ones out there with cards for every occasion. But, did you know that the Mail app on Mac offers these types of messages too?
NOTE: This feature has been removed from the Mail app since the release of macOS Mojave in 2018.
If you want to send a card-like email, check out the Stationery options instead. The feature in your Mail app on Mac is easy to use, gives you cool cards to pick from, and lets you say exactly what you want to say.
