Font/layout inconsistencies in custom campaign template

Hello there,

I've created a custom campaign template and while a majority of the email is desktop/mobile responsive, there are certain font/layout consistencies (please refer to the attached screenshots).

The issues shown in the screenshots are:-

a. Font type for the header and footer have been set to Tahoma but display as Times New Roman in mobile;

b. Layout of the 'Contact' and 'Connect' section are not aligned in mobile as displayed in desktop; I've tried reducing the font size and image size of the social media logos but the issue still stands.

Any assistance in this matter will be greatly appreciated.

Thank you.
