I want to create a landing page to be able to email a link to customers to refer friends, in order to collect email address on the page.
Hello @TWhite !
You do have the opportunity to either have Square host a landing page or has the embed code for your own webpage. It's geared specifically to your business as well.
On your dashboard, go to Customers -> Settings -> Email Collection
The point of sale verbiage is listed here as well as the options for hosted or embed code.
Hope this helps!
