Build a harmless example
For a broken calendar button, use an empty example event called “Sample visit.” Take the screenshot in that view, then reopen the finished image before sending it. A crop preview and the file that actually gets attached can differ. Use the smallest view that reproduces the problem. If the fault concerns a button, a picture of that button and the relevant error may be enough.
Read the final image edge to edge
Look at browser tabs, address bars, notification banners, recent files, account initials and reflections. Examine the exported image outside the editing tool. A movable overlay in an editable document is poor protection; share a finished image whose pixels contain only the intended area.
Send the right attachment
Check the thumbnail and file name in the message before sending. Say which step caused the screenshot and what you expected. If you need to show more context, recreate it with fictional records first. Avoid sending a private conversation or household database just to demonstrate a layout problem.
