See sent emails

Hello Info1728, 

Welcome to the Community page, 

There is no way in Quickbooks to see sent emails, you would need to leave this as feedback within the main cog wheel. The only way around this is to BCC yourself into the invoices ect to be able to see what has been sent and what has not or you could view the audit log of the invoice and it should show as sent there, you just need to open the invoice and select more>audit history.
