```

### Example 2: Legitimate Interest Assessment

**Input:**
```
We want to email our existing customers about related products.
Do we need consent or can we use legitimate interest?
```

**Output:**
```
## Legitimate Interest Assessment: Customer Cross-Sell

### Summary

You can likely rely on legitimate interest (not consent) for
emailing existing customers about **similar** products, but must
complete this assessment and offer easy opt-out.

---

### Three-Part LIA Test

#### 1. Purpose Test: Is There a Legitimate Interest?

**Interest:** Promote related products to existing customers
**Legitimacy:** Yes - recognized business interest in customer development
**Benefit:** Revenue growth, customer relationship deepening

✅ **PASS**

---

#### 2. Necessity Test: Is Processing Necessary?

| Question | Answer |
|----------|--------|
| Is email necessary to achieve the interest? | Yes - direct communication channel |
| Is there a less intrusive way? | In-app notifications possible but less effective |
| Is the processing proportionate? | Yes - limited frequency, relevant content |

✅ **PASS** (with conditions)

**Conditions:**
- Limit to genuinely related products
- Reasonable frequency (not daily)
- Honor opt-outs immediately

---

#### 3. Balancing Test: Individual Rights vs. Your Interest

| Factor | Assessment |
|--------|------------|
| Nature of data | Basic contact info - low sensitivity |
| Reasonable expectations | Customers expect marketing from sellers |
| Relationship | Existing customer relationship |
| Impact on individual | Minor inconvenience, easy to opt out |
| Safeguards | Opt-out in every email |

✅ **PASS**

---

### Conclusion

**Lawful Basis:** Legitimate Interest (Article 6(1)(f))

**Requirements for Compliance:**

1. **Document this LIA** and keep on file
2. **Include in privacy notice:**
   "We may contact existing customers about similar products
   based on legitimate interest. You can opt out at any time."
3. **Easy opt-out:** Every email must have unsubscribe
4. **Honor preferences:** Immediate suppression on opt-out
5. **Similar products only:** Don't expand to unrelated offerings
6. **Reasonable frequency:** No more than weekly

---

### Template Email Footer

```
You're receiving this as a valued [Company] customer.

Not interested in product updates?
[Opt out of marketing] | [Manage preferences]

This email was sent based on our legitimate interest in keeping
customers informed about relevant products. See our Privacy Notice
for details and your rights.
```

---

### When This Doesn't Apply

Use **consent** instead if:
- Products are significantly different
- Customer bought once 2+ years ago
- You acquired data from third party
- Customer previously opted out
- Emails are primarily promotional (not informational)
```

## Skill Boundaries
