I sent an email with an attachment to myself and now that email has been sent over 4000 times

I sent an email to myself and em client keeps sending it repeatedly. I have received the same email over 4000 times and has not stopped. I uninstalled em client and reinstalled but it has not fixed the problem

Check if the email is still in your Outbox, both for your account folders and Local Folders. If it is, delete it.

If you can’t see Local Folders, you can enable them in Menu > Tools > Settings > General > Show Local Folders.
