What if I do not have my customers' email address?
You can send them a Text Message rather than an email feedback request.
Or you can direct them to your website Feedback Page. Your customers can click the "Leave Feedback" button and use the feedback system with any web enabled device, smartphone to desktop computer. Your business also gets a unique feedback web address that can be added to printed media, invoices, bills, tabs, receipts, business cards, QR codes, SMS, etc - and does not require you to know the customers email or name.
Once you introduce the feedback process to your customers you can start collecting their email address or mobile phone number. Trust Builder works great on mobile devices (iPhone, Android, iPads, etc), so you can collect the customer's name, email address or Text Number and add to your customer records while they are at your place of business.
