In Gmail, whenever I send an email I want to get a copy of the message that I sent in my inbox, 100% of the time. How can I do this? 
Get sent emails copy in inbox

I have not found a way to add the inbox label to all outgoing messages. But you can use multiple inboxes to get sent mail to the top of the windowGo to settings/Labs and select Multiple inboxesSave ChangesYou should now see a Multiple inboxes tab in settings.GMail will let you specify a search query. In the first box enter is:Sent Mail without the quotes.Set the maximum page size to a larger number. It didn't complain about using 50, but I don't know if there is a maximum value.Optional: Set Extra panels positioning to Above the inbox. This will put the Sent Mail label above the main inbox.Save changesThere may be a couple of second lag the first time you go back to the main page, becuse it has to execute the new query.It does the job with a couple of issues: Each inbox has its own < and > button to move through the listEach inbox has its own view all button which jumps you to the labelThe gear button is only on the tool bar above the main inbox section.
