Ecwid by Lightspeed requires customers' consent to receive marketing emails - https://developers.ecwid.com/faq#accept-marketing-emails
So, applications like Gratisfaction have to comply and track the customers' consent and send emails accordingly.
Here is an explanation about the Ecwid by Lightspeed permissions:
- Enroll only: Users will be enrolled in the Gratisfaction- 'Loyalty and Referral program' but won't be sent any emails from Gratisfaction.
- Enroll & send: Users have granted permission to receive emails from Gratisfaction. So in addition to being enrolled in the Gratisfaction- 'Loyalty and Referral program', they will also be sent all relevant emails from Gratisfaction.
- Campaigns only: Users who have registered directly to one of your Gratisfaction campaigns will only receive the campaign level emails
- All: User grants permission in Ecwid by Lightspeed itself. Such users will receive all types of emails.
