How can I check if my iCloud emails were delivered?
Using Mail with icloud sent emails radomly not arriving but not flagged as returned , only communication from recipient indication non arrival ?

Are the emails actually in your Sent folder? Newer versions of Mail have a feature where you can set a delay before the email is actually "sent", so you can change your mind and cancel sending.I believe the default is five or 10 seconds.
If you are one of those people (especially on their phone) who quits programs when not using them, and if you send emails and then quit the app before the email is actually sent and moved from your Outbox to your Sent folder, then the email simply vanishes as if never written.
So, are these emails in your Sent folder? If so, then they have been sent from your Mail client to your outbound mail server and thus onwards for delivery. If they never made it after that, something else is wrong.
