Kirk Trachy, Quick Base Employee / full time Quick Base Evangelist has an app in the exchange called Magic Buttons. I suggest downloading it and dating it in the title in your local copy as he keep reloading it with new tricks, but his app always has the same name. So hen you download the new one every few months, delete your old one.
He has a tip there on how to make buttons that look good in emails
// Begin button style
var text bgcolor = "#4285F4";
var text txtcolor = "white";
var text style = "style=\"text-decoration: none; width: 120px; text-align: center; background:" & $bgcolor & "; border-radius: 5px; padding: 8px 20px; color: " & $txtcolor & "; display: inline-block; font: normal 700 24px/1 \"Calibri\", sans-serif; text-shadow: none;";
// End button style
"<a " & $style & " href='
https://www.w3schools.com/colors/colors_brands.asp' title='Brand Colors'>Google Blue</a>"
// Great resource to create our own style of button.
