问题
I am creating an email template, the specs that I am working to have the measurements in MS word font size. Being a print medium, this is in pt. However email is a screen based medium (https://stackoverflow.com/a/3557275/989852).
Should the font-sizes (and all other dimensions for that matter) in an email template be specified in pt or px?

(Excerpt: Paul Dyke - http://www.adestra.com/what-need-know-using-fonts-in-email/)
em doesn’t work with fonts in email as email clients have different default sizes.
% is another scalable font unit, similar to em except 100% will always equal the default size.
pt is sometimes used. One point is equal to 1/72 of an inch. But why use a unit that is a throwback to the printing industry?
In my opinion, pixels are the best option. Email designs are often pixel perfect – lots of sliced images in different table cells that have to appear seamless. Having your text behave in a similar way makes sense.
And it's also my opinion

I always use px for email template because most of the email i create is business marketing purpose. There is no need to print it, and i want font same sized for all devices. But now a days i'm creating some email template which is responsive at that time i'll prefer to em. since i need to re size according to screen. why px
