Along the sames line as this, I have a fully HTML email I’m putting together and it has a background image and a video that show up in the preview window but never on email send.
In regards to the video can we use iframe at all?
and the background image I am using :
style="background:url(https://background_image.png);background-repeat:no-repeat; background-size:contain;background-position:center; ;
any help is appreciated
