Hi @apettit ,
You're almost there with your code! You've referenced the DataCard correctly, but we also need to specify what property/value we need from the DataCard.
I've recreated it at my end, injecting a Person column from SharePoint into a form control. I have a button with the following in the OnSelect property:
Launch("mailto:" & DataCardValue15.Selected.Email)
I get the desired result - a fresh email opening up ready to type.
FYI, you can also send a complete email from Power Apps directly, using the Office 365 Outlook connector. With that connector added to your app, you could do something like this in the OnSelect property of the image instead, if you needed to:
Office365Outlook.SendEmailV2(
//To
DataCardValue15.Selected.Email,
// Subject
"Here is my subject",
// Body
"Here is my body")
You can make the subject & body dynamic too, by referencing other variables/outputs as needed.
Hope that helps!
