Yes. An email address is required to complete every FIXR Pay purchase.
It is used to send the customer their ticket or confirmation and link the purchase to their customer record in FIXR. If the customer does not already have a FIXR account, they can access their purchase later using that email address.
FIXR Pay links each purchase to a customer record, giving you a more complete view of sales and audience activity.
Entering an email address does not currently include a marketing opt-in. Any marketing communications must be managed in line with your usual consent and communications requirements.
