Gmail lets you unsend emails for a certain time. Make sure the feature is enabled.

Did you just send that message to Sam W. instead of Sam G.? It may not be too late. If you use Gmail on the web, you may be able to unsend the message you just sent.

Gmail can hold back delivering emails for up to 30 seconds after you have clicked Send. You can "unsend" an email and recover from false recipients, spelling mistakes, a sub-optimal subject and maybe forgotten attachments.
