Thank you for posting your query in the Community. The Mail app should be able to fetch new emails automatically; have you checked the ‘Fetch New Data’ settings for Rogers’ email?
Go to Settings > Mail > Accounts > Rogers email > Fetch New Data. If ‘Push’ is selected and it’s not downloading the emails automatically, then you can try selecting ‘Fetch’ and select ‘Automatically’.
Please keep us posted on the outcome.
