Thanks , one more plus to opalstack !
Does the logo have to be SVG ?
or
can we use
.png ?
.jpg ?
There seems to be different opinions
about this - therefore your experience
would be valuable.
Although SVG is standard and should work
we have found with browsers that standards
.png and .jpg work better.
And if a client opens email with a browser
then .png and .jpg would most likely work.
