Avoiding spam complaints in Portugal requires strict adherence to the Portuguese Data Protection Authority (APDP) regulations, which implement the General Data Protection Regulation (GDPR). Here are key steps to ensure compliance and minimize complaints:
Obtain Explicit Consent: This is paramount. You must get a clear, unambiguous opt-in from individuals before sending them marketing messages via SMS or email. This means they must actively check a box or take a similar affirmative action. Pre-ticked boxes are illegal. For existing contacts, validate if you have a legitimate basis for contact, potentially portugal phone number list requiring re-consent.
Provide Clear Opt-Out: Every communication must include a simple, free, and obvious way for recipients to unsubscribe or opt-out. For SMS, this is often a keyword like "STOP". For email, a clear unsubscribe link is mandatory. Ensure these mechanisms work instantly.
Be Transparent: Clearly state who you are, why you are contacting them, and what data you will use. Provide easy access to your privacy policy detailing how data is collected, used, and protected.
Keep Records: Maintain documented proof of consent, including when it was obtained, the method, and the content of the consent request.
Segment Your Lists: Only send relevant content to interested parties. Generic blasts increase the likelihood of complaints.
Respect Opt-Outs Immediately: Never attempt to re-contact someone who has unsubscribed. This is a common cause of complaints and severe penalties.
Use Double Opt-In (Recommended): For email, sending a confirmation link after the initial signup significantly proves consent and ensures the email address is valid and belongs to the person who signed up.
Limit Frequency: Don't overwhelm recipients with excessive messages.
Failure to comply can result in significant fines from APDP. Always prioritize ethical data handling and user preference to build trust and avoid being classified as spam.
