Party invite

I was invited verbally about two weeks ago by 1 host of a 4 host party to an upcoming party. He told my husband and myself to save the date. I just found out that an evite went out earlier this week and we did not receive one. This is an event we have been invited to in the past. However I certainly dont feel like it would be appropriate for us to ask if we were included on the guest list or not but I do feel this may have been an oversight. Any advice?
