Email HTML template - dark mode

Hi there,
I've created a template in the Postcards app, but I need it finalised and altered for dark mode.

This might require a re-jig of our logo which is on a black background with white text.

The HTML template needs to be responsive/mobile optimised.

It should also be improved if possible with any enhancements to the design, structure welcomed.

I'm looking for a UK based freelancer, who I can work with on a number of templates in the future. Please don't apply if you are outside the UK.

Thanks
David
