The GDPR Double Opt-In Rule Every Greece Marketing Sender Gets Wrong

Greece's SMS marketing compliance landscape is governed by two overlapping regimes: the EU's General Data Protection Regulation (GDPR) and the Greek ePrivacy Law, both enforced by EETT (Hellenic Telecommunications and Post Commission, eett.gr). The critical gotcha most senders miss is that soft opt-in does not exist in Greece for marketing SMS.

In some countries, a customer who purchases goods or services may be automatically eligible to receive marketing messages about similar products (soft opt-in). Not in Greece. The law requires explicit, prior, affirmative consent—often called double opt-in—before you send any SMS for marketing, promotional, or non-transactional purposes. This means a sender must obtain a first confirmation (e.g., a form submission), then send a confirmation message asking the recipient to verify their choice, and finally record proof that the recipient confirmed. Senders who skip the double opt-in step expose themselves to enforcement action by EETT, which regularly publishes notices to major senders about violations.

A second, often-overlooked rule: consent must be separate from other terms and conditions. You cannot bury SMS opt-in in a privacy policy or terms-of-service checkbox. It must be standalone, granular, and documented. If you cannot produce a dated record of explicit SMS consent for each recipient, you should not send to that number.

GDPR and Greek ePrivacy Law: Consent Framework and EETT Enforcement

Greece's ePrivacy Law implements the European Electronic Communications Privacy Directive and works in tandem with GDPR Article 21 and the ePrivacy Directive. Both require prior, explicit consent for any direct marketing communication, including SMS. The regulator, EETT, maintains a sender registry and publishes compliance guidelines on eett.gr.

Key requirements:

• Explicit opt-in (double opt-in preferred): Obtain written, affirmative consent before sending any marketing SMS. A soft opt-in (purchase-based consent) does not satisfy the law.
• Separate consent: SMS marketing opt-in must be independent of other consents or terms. A user cannot consent to SMS merely by accepting privacy terms.
• Identifier transparency: Every SMS must clearly identify the sender (e.g., company name or registered sender ID) and include a mechanism to opt out (e.g., "Reply STOP to unsubscribe").
• Retention and proof: Maintain records of consent for at least 3 years. This includes consent date, method, and any opt-out instructions.
• EETT registry: It is strongly recommended to register your alphanumeric sender ID with EETT to demonstrate compliance to carriers and the regulator.

Senders who violate these rules may face enforcement action from EETT, which has published notices to major international platforms regarding non-compliance. While EETT does not publicly announce specific fines for all violations, the regulator has a history of requiring corrective action and may impose sanctions in the six-figure range for systemic breaches.

Quiet hours and Sunday restrictions: Marketing SMS must not be sent between 20:00 and 08:00 EET, nor on Sundays. Transactional messages (OTP, delivery notifications, appointment reminders) may be sent outside quiet hours if they are not promotional.

Mobile Operators and Network Reach in Greece

Native Greek market names: Κοσμότε (Cosmote), Βοντάφον Ελλάδας (Vodafone Greece), Wind Hellas (Ουίντ Ελλάς).

Vodafone Greece (38% market share): The largest operator in Greece. Vodafone Greece operates on 2G/3G/4G/5G networks and handles the majority of A2P traffic. Direct interconnection with smsroute.cc ensures high deliverability and low latency across Vodafone's subscriber base.

Cosmote (35% market share): The second-largest operator and a subsidiary of OTE (formerly Hellenic Telecommunications Organization). Cosmote operates nationwide and is the default carrier for many landline upgrades to mobile. A2P SMS to Cosmote is reliable and well-supported via standard carrier gateways.

Wind Hellas (23% market share): The third-largest operator, now part of the Vodafone group (though operationally distinct). Wind Hellas serves consumers and business customers with 4G/5G coverage. SMS delivery to Wind Hellas is direct and typically achieves latency in the 150–250 ms range.

Nova (4% market share): A smaller but growing operator focused on mobile-only services. Nova operates on Vodafone infrastructure via an MVNO arrangement. SMS to Nova numbers is routed through Vodafone's network and is fully supported.

Mobile number format: Greek mobile numbers use the 69x prefix (e.g., +30 69x xxx xxxx). Landlines use the 2x prefix (e.g., +30 2x xxxx xxxx). Always send to E.164 format (+30 followed by the full number without leading zero) to avoid routing errors.

Step 1: Create an account at smsroute.cc using an email address and a crypto wallet address (Bitcoin, USDT, Ethereum, Litecoin, Monero, or Solana). No phone verification, no ID, no corporate documents required. Account setup takes less than 2 minutes.
