Missing emails

I have just downloaded eM Client as a trial. On starting up it received a couple of gmails, but neither has appeared on my other machines that use gmail or Outlook. How do I find them? Has eM Client swallowed them?

did you set the account using POP3 or IMAP protocol?

IMAP - I think. It told me it was better

I am pretty sure eM Client could not delete it. Please login to your mail in a browser and make sure the messages are still on the server.
