Hi Tori,
Are you or are you considering offering free content in exchange for your customer's email address? For example, some sites will offer a video or ebook in exchange for an email address. If you are using this method of email collection, I'd like to invite you as a beta tester for a Shopify app that I developed. Email me at felixthea@gmail.com and I can get things going for you. I am starting the beta period testing next week.
Thanks
Felix
