Email slow to arrive from another tpg email address

[jnovice1]

My daughter has an email address on our tpg account. 

She sent an email to her Dad via TPG Post Office. 

Her Dad's tpg email didn't receive it until 3.5 hours later.  Why would there be a delay when they are both with TPG and also have emails in the same TPG NBN account?

Hi jnovice1,

I recommend to report your email issue directly to postmaster@tpg.com.au and include your TPG account details. Let me know if need further help.

Regards,
