### 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?

✅ 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

✅ 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

Not interested in product updates?

When This Doesn't Apply

Use consent instead if:

• Products are significantly different
