emailing existing customers about **similar** products, but must
complete this assessment and offer easy opt-out.

| Is the processing proportionate? | Yes - limited frequency, relevant content |

✅ **PASS** (with conditions)

**Conditions:**
- Limit to genuinely related products
- Reasonable frequency (not daily)
