Desk email templates not mobile friendly

Desk email templates not mobile friendly

Greetings,
I am just in the process of setting up my new zoho desk for our company.

I have been dissapointed to find the email sent out are not mobile friendly, even a marginally.

Can anyone help me understand how to provide better viewing on a small screen, while still keeping some formatting on larger screens.

Regards,
Stephen
