To optimize the ordering flow for loyalty contacts coming directly from a Leat Email, you can add a session token to the CTA link in your email campaigns.
Add merge tag to your email template
To enable this, append a session token merge tag to the link pointing to your orderBilly venue.
Example:
https://orderbilly.com/billy-venue?sessiontoken={{contact.session_token}}
If the merge tag is not available, enable the Contact Session Token feature in your Leat account settings under the Features tab.
