Frequently asked questions
Do I need a preference center if I already have an unsubscribe link in my emails?+
Yes, absolutely. The unsubscribe link is mandatory, but it's not enough. The preference center allows your contacts to choose what they want to receive, rather than unsubscribing entirely. It's a great way to reduce churn, provide better service, and, of course, strengthen your compliance.
Can I combine multiple marketing purposes under one opt-in button?+
No, the CNIL is very clear: each purpose must be subject to separate consent. For example, commercial prospecting by email, subscribing to a newsletter, or sending personalized content must be separated. In Marketo, this often involves managing multiple consent fields, but it's the key to strong compliance.
How can I prove that my contacts have given their consent?+
Marketo doesn't do this natively, but we have solutions for that! Thanks to smart programs, tracking fields, and a little cleverness, you can record the date, source, and context of consent. This evidence can be useful in the event of an audit or complaint. At Merlin/Leonard, we help you implement this properly.
Can you be GDPR compliant without sacrificing marketing performance?+
Of course, and that's the whole point. A good GDPR system builds trust and allows you to work with a more engaged base. You gain in lead quality, deliverability, and brand image. With the right Marketo tools, it's entirely possible to balance performance and compliance.
