Emails not going post cvs upload

Hi Team,

I have checked my sendinblue transactional email logs, what i can see only 8 emails sent related to shipping details,

But i had uploaded 3-4 files , 3-4 days back, over all around 50-100 order data should be there.

Fyi.. i have uploaded 2 file today also, but no emails in the provider logs.

Can you please help us to see why these emails did not went? and is there any chance to send them again to inform customer about there shipping tracking details?

My site details i have given you in my other tickets, hope you have them.

This is bit urgent as many customers are enquiring now about tracking codes.
