Template Checker

Good Morning

I struggle with changing the Mail Templates… when I change even small things (starting from Oxygen), the Builder colapses, error 500 sporadically shows up, the Content Tab doesn’t show the edit-Toolbar.

So my “small” adjustments are somehow wrong…

It there any Checker, that I can throw my newly made templates at and it tells me, what’s still wrong?
