Applescript: return focus to another app after script runs

Question

I'm currently running the following script via Hazel to back up plain text notes in a specific folder to Evernote:
tell application "Evernote"
  activate
  create note from file theFile notebook {"!inbox"} tags {"to review"}
end
Is there any way to do this so it happens in the background i.e. returns focus to whatever app was active when the script is triggered?
Thanks in advance for any responses.
