There could be a number of reasons for this. Below are a few possibilities:
- The customer has not ordered from you before.
- They are not an active customer (customer that has not ordered within the last 12 months).
- The customer has opted out of receiving communication from your brand.
- The customer has received communication from another restaurant from the same brand in the last 60 minutes.
- The customer is not part of the cohort/customer segments.
