An operational bill tells a guest what happened during a visit. A promotion asks to contact that guest again. They should not share an accidental permission shortcut.
Explain what an email address is for
If an email is requested for a final bill, show that purpose in plain language. Avoid hiding campaign language in a broad account checkbox. Guests who do not want marketing should still receive the core service they requested where supported.
Log meaningful preference changes
Use a distinct, optional email-marketing choice and note when it was presented, accepted or withdrawn. Design the suppression process before creating a campaign editor. Never rely on a stale spreadsheet of opt-ins.
Keep delivery gated until verified
SMTP credentials, domain alignment, deliverability testing, unsubscribe links and compliance approval all matter. A test email arriving in one inbox is not evidence of a safe mass-sending system. KyaLoge's outbound email remains disabled pending verification.
Here's what this looks like in practice.
Illustrative situation, not a claim about a real KyaLoge customer.
The cashier asks whether a guest wants an emailed final statement. The guest agrees. That is not an invitation to add the address to a weekly promotions list.
A better way to handle it
Keep transactional contact purpose and optional promotional email preference separate. Store meaningful consent state, allow withdrawal, and gate sending until SMTP, domain and suppression rules have been tested.
In a test flow, decline promotions but request the final bill. Inspect the stored preferences and what the staff interface claims it may send.

What to check before making a decision
- 01Clarify receipt purpose beside the input.
- 02Make marketing optional and off by default.
- 03Give guests a meaningful preference or withdrawal route.
- 04Test delivery and suppression without using real campaigns prematurely.
Keep the useful part.
A restaurant should keep a human-readable privacy notice alongside its technical consent records.
