Email Templates Display badly on real devices

Hi VillaTheme support

I created some Woocommerce E-Mail templates that look good in your preview but the design kinda breaks when i look at them in real Mail-Clients.

For example:
– Some columns are oriented to the bottom instead of top
– Beneath the Total-Price the line with the VAT breaks into 3 Lines
– On mobile the section with the Total price still shows up as 2 Columns which looks terrible and some of things are not properly centered

Can you assist with this?
I can also show you screenshots.

Kind regards
Chris
