Customer e-mail accounts are an asset of our company.  Since we invest in capturing these with our store expenses and advertising, this detail should be free and not a paid for subscription capitalized upon by Square.  Square is a payment processor, and bundling in the e-marketing feature for pay seems unethical.  It is fine to make this feature available as an add on for those who do not have other e-marketing programs.  For us, Square's intent to control this asset of ours simply fractures our emarketing efforts = dfiierent channel, image options, and effort.  Square sites FCC regs about access to customer info: why not insert a button at point of sale that gives our customers the option of subscribing to our marketing since we are the face of their retail experience and have an FCC regulated e-marketing program already in place.  I feel that Square is reselling me my own property: my customers.  I have already invested in their acquisition once!!
