## Pre-send collision check

- [ ] A person in two groups receives one correct message or intentionally distinct messages.
- [ ] Cancellation, refund and transfer update membership before a scheduled send.
- [ ] Unknown language or missing field has an approved fallback.
- [ ] Each segment has a sample record that must receive the message and one that must not.
- [ ] The real sending tool, not only this worksheet, applies the intended AND/OR conditions and suppressions.
- [ ] No private accessibility, dietary or medical details appear in promotional tags or shared exports.
- [ ] Public event details and support contact remain current if email is missed.

Keep attendee-level evidence in an access-controlled operational system, not this shareable worksheet. Classify marketing and service messages with the responsible privacy/communications owner for the relevant jurisdictions.
