It would be really great to be able to merge contact details into text for the action buttons. You see a lot of charity emails with gift arrays displayed as button links:
Give $25 to feed a hungry child
Give $50 to buy a rescue kit
At the moment we can have only static text in those buttons, but you want to always gauge the ask amounts based on the donor's previous giving level, so it would be amazing if we could simply merge the gift amounts and other custom text into those buttons.
