Here is a list of 10 tools you could use to collect email and SMS opt-ins from customers in on-site hypermarkets:

  1. Custom touch pads: Use touchscreen tablets with custom registration forms to make it easy for customers to sign up by providing their contact information.
  2. Interactive terminals: Set up interactive kiosks where customers can enter their contact information to sign up for email and text notifications.
  3. Custom QR codes: Display custom QR codes on posters or flyers, which customers can scan to access an online registration form.
  4. Digital loyalty cards: Offer digital loyalty cards that require registration with an email address and phone number to benefit from special offers.
  5. Dedicated mobile applications: Build a mobile app for your hypermarket that allows customers to sign up for notifications while providing additional features and benefits.
  6. In-store registration booths: Set up in-store registration booths with interactive screens to guide customers through the registration process.
  7. Electronic suggestion boxes: Place electronic suggestion boxes near exits where customers can leave their contact information in exchange for the opportunity to receive special offers.
  8. Promotional campaigns at the cash register: Offer cash register incentives by offering immediate discounts in exchange for opting in to emails or text messages.
  9. In-store entertainment: Organize special events or in-store events where customers can sign up to participate and receive future information.
  10. Online data collection with pick-up point: Allow customers to register online through your website and then pick up a gift or coupon in-store, which will encourage more registrations.

Make sure you comply with data protection regulations and provide clear options for consent and unsubscription at any time.
