I have a lead form in my website (A website about High-End Fashion) in which visitors can contact a sales representative about product A. There is no opt-in checkbox, just a couple of text fields (phone number, e-mail etc...) and I received several thousands of submissions from customers in the UK. The form's purpose is to schedule an appointment.
I want to send these leads a marketing mail of product B. It's a different product from the same brand and I know it's relevant to those leads - But, it's a completely different product category.
- Can I legally send such e-mails?
