How to Follow Up with Leads Without Breaking GDPR
Automated SMS follow-up and GDPR compliance aren't mutually exclusive. Here's exactly how we handle consent, data processing, and opt-outs for Finnish and Swedish studios.
"Can I really send automated SMS to leads?" It's the most common question we get from Nordic gym owners. The answer is yes — but you need to do it right. Here's exactly how GDPR-compliant lead follow-up works.
The Legal Basis: Legitimate Interest When someone fills out your lead form saying "I want a free trial at Your Gym," they're expressing clear interest in your services. Under GDPR Article 6(1)(f), you can process their data based on legitimate interest — the interest being to respond to their request. This is different from cold outreach. You're not buying lists or scraping data. You're responding to a direct inquiry.
Consent for Marketing The initial follow-up (SMS + email with booking link) falls under legitimate interest. But the Day 30 re-engagement? That's marketing. For this, you need consent. Best practice: Include a consent checkbox on your lead form. Something like: "I'd like to receive offers and updates from [Studio Name]. You can unsubscribe at any time." Without this consent, your automated sequence should stop at the initial follow-up cycle.
Data Processing Requirements 1. **EU data residency**: All data must stay in EU data centers. LeadFlow uses Twilio EU (Ireland) and Brevo EU (France) 2. **Data Processing Agreement (DPA)**: Required between you (controller) and LeadFlow (processor). We provide this 3. **Data minimization**: Only collect what you need (name, phone, email). No unnecessary data 4. **Retention limits**: Define how long you keep lead data. We default to 12 months post-interaction
Opt-Out Handling Every SMS must include an opt-out mechanism. LeadFlow automatically: - Recognizes STOP, CANCEL, and LOPETA (Finnish) replies - Removes the contact from all sequences immediately - Confirms the opt-out with a final message - Logs the opt-out for compliance records
The Privacy Notice Your lead form must link to a privacy notice explaining: - Who is collecting data (your studio) - Why (to respond to their trial request) - What data (name, phone, email) - How long (retention period) - Their rights (access, rectify, delete) - How to complain (Data Protection Ombudsman) GDPR compliance isn't a barrier to automation — it's a framework for doing it responsibly.
