@Aaron2222 good spotting. More info here https://www.mercury.co.nz/broadband/wireless-broadband
In that case, the OP has been told info that contradicts their help pages. They clearly say you can send mail from a Mercury connection, and it's a connection they sell, so they should have sorted it to work. Nothing obvious from the sales page that says this important (email) service won't actually work, so it's reasonable to expect that it will work OK.
