Ground Mail Was a Better Option is an achievement/trophy in Deus Ex: Mankind Divided. In order to get the achievement, you must disable a drone using Remote Hacking without making any mistakes. As Remote Hacking is an experimental augmentation, this achievement is only obtainable after they have been unlocked in M3: Getting in Top Shape Again.
Remote Hacking must be unlocked and upgraded to include "Security Domination" so that drones can be hacked. When a drone is encountered and you begin remote hacking it, you must click on all the fuzzy areas without missing one accidentally to get the achievement.
The title of the achievement alludes to the increasing use of drones to deliver items such as food and packages.
