Keeping Your Digital Marketing Effective & Legal

A practical guide for Irish businesses navigating GDPR, the Digital Services Act, ePrivacy, and ethical marketing in 2025. By Matrix Internet | Updated May 2025 | 12 min read

Ireland is not just a participant in EU digital law — it is the enforcement capital of it. With Meta, Google, TikTok, Apple, and dozens more tech giants headquartered in Dublin, the Data Protection Commission (DPC) is under constant scrutiny. As an Irish business, you operate in the most closely watched data jurisdiction in Europe. That is both a challenge and an opportunity.

Digital marketing is indispensable for any modern Irish business. But the legal and regulatory environment around how you collect data, target audiences, run competitions, and communicate with customers has never been more complex. This guide breaks down what you need to know — and what you need to do — to market effectively without falling foul of Irish or EU law.

Why Ireland Is Different

Ireland is home to the European headquarters of virtually every major tech and platform company. That makes the Data Protection Commission (DPC) — Ireland’s national data regulator — the de facto lead supervisory authority for GDPR enforcement across the EU for these platforms. Irish businesses benefit from proximity to the latest regulatory thinking, but are also held to a higher standard of awareness.

Between 2018 and 2024, the DPC issued fines totalling over €3.67 billion against companies processing EU citizens’ data unlawfully. While most of these involved tech giants, the same laws apply in full to a small Irish retailer running a Facebook ad campaign or a Dublin restaurant collecting email addresses.

Key Irish & EU Regulatory Bodies

• Data Protection Commission (DPC) — Ireland’s GDPR authority
• ComReg — Electronic communications regulator
• CCPC — Competition & Consumer Protection Commission
• ASAI — Advertising Standards Authority Ireland
• EDPB — European Data Protection Board
• Digital Services Act — EU Commission DSA portal

GDPR & Data Collection: What Irish Marketers Must Know

The General Data Protection Regulation (GDPR), enacted in 2018 and enforced in Ireland via the Data Protection Act 2018, remains the cornerstone of how you can legally collect and use personal data for marketing purposes.

Lawful Bases for Marketing

You cannot market to people simply because you have their data. You need a lawful basis under Article 6 GDPR. For most marketing activities, the relevant bases are:

Consent — The person has freely, specifically, informed, and unambiguously agreed. Pre-ticked boxes, bundled consent, or vague language will not pass DPC scrutiny. Consent must be as easy to withdraw as to give.

Legitimate Interests — You have a genuine business reason that is not overridden by the person’s rights. This requires a documented Legitimate Interests Assessment (LIA). The DPC has stated clearly that legitimate interests cannot be used as a shortcut around consent for direct marketing.

Contractual Necessity — Processing is necessary to perform a contract with the person (e.g., sending order confirmations). This does not extend to promotional marketing.

Important: Under the ePrivacy Regulations (SI 336/2011), which implement the EU’s ePrivacy Directive in Ireland, sending marketing emails or SMS to individuals without prior consent is unlawful — regardless of any GDPR lawful basis. Consent under ePrivacy must be obtained before the communication, not after. Fines of up to €5,000 per offence can be imposed by ComReg.

Cookies & Tracking

The DPC’s Cookie Guidance (2020) makes clear that placing non-essential cookies — including analytics and advertising cookies — requires freely given, prior consent. Ireland’s regulators have explicitly rejected “consent walls” (blocking access to content unless a user accepts all cookies).

Best Practice: Your cookie banner must present genuine choice. “Accept All” and “Reject All” must be equally prominent. Hiding the reject option behind additional clicks, or using dark UX patterns (misleading colours, confusing language), is a breach of both the ePrivacy Regulations and GDPR’s requirement for freely given consent.

The Digital Services Act: New Obligations for Irish Businesses

The EU’s Digital Services Act (DSA), which came into full force in February 2024, fundamentally reshapes the obligations of online platforms operating in the EU — including many Irish businesses.

What the DSA Means for Your Marketing

Targeted advertising restrictions: The DSA prohibits targeting ads based on sensitive personal data (religion, sexuality, ethnicity, political opinion, health). It also bans all targeted advertising directed at minors. If you are using Meta, Google, or any ad platform to run campaigns, ensure your audience targeting does not rely on these categories.

Transparency in advertising: All online ads must clearly be labelled as advertising. Users must be able to see, on request, why they are being shown a specific ad. As an advertiser, you should ensure your platform settings comply and that any sponsored content on social media is clearly disclosed.

Algorithm transparency: Large platforms must now offer users the option of non-personalised feeds. This may reduce the effectiveness of organic reach strategies that rely heavily on algorithmic amplification — a factor Irish marketing teams should build into their content strategies.

EU Law: The DSA is directly applicable in all EU Member States, including Ireland. The CCPC and Coimisiún na Meán (the Media Commission) share enforcement responsibilities in Ireland. Fines for very large platforms can reach 6% of global annual turnover.

Email & SMS Marketing: The Rules in Ireland

Email and SMS marketing are governed by both GDPR and the ePrivacy Regulations. The distinction between B2C and B2B makes a practical difference here.

Business-to-Consumer (B2C)

Sending promotional emails or texts to individual consumers requires prior opt-in consent, with one narrow exception: the “soft opt-in” or existing customer exemption. Under this rule, if someone has recently purchased from you (or entered clear negotiations to do so), you may market similar products and services to them via email — provided you gave them a clear opportunity to opt out at the time of collection, and every subsequent message contains an unsubscribe option.

Business-to-Business (B2B)

Marketing to corporate email addresses (e.g., info@company.ie) sits in a slightly different position. The ePrivacy Regulations provide more flexibility for B2B communications, but GDPR still applies to named individual employees’ addresses (e.g., john@company.ie). You must always have a clear unsubscribe mechanism and honour opt-outs promptly.

Important: Purchasing third-party marketing lists is high-risk in Ireland. Unless the list provider can demonstrate that each contact validly consented to receive marketing from businesses like yours — with full transparency about who the data would be shared with — using that list may breach both GDPR and the ePrivacy Regulations. The DPC has taken enforcement action over exactly this issue.

Social Media Marketing: Staying Compliant

Social media is where many Irish businesses face the most legal complexity, because the platforms themselves are simultaneously subject to regulation and the tools through which you deliver your campaigns.

Influencer Marketing & Disclosure

The ASAI Code of Standards and the EU’s Unfair Commercial Practices Directive both require that paid partnerships, gifted products, and sponsored content be clearly labelled. In Ireland, the ASAI has issued specific guidance on influencer marketing. The standard is clear: if money, free products, or any other benefit has been given in exchange for a post, it must be disclosed — unambiguously and prominently. #ad or #gifted at the start of a post is required; burying it at the end or using vague terms like #collab is insufficient.

From 2024, Coimisiún na Meán has been strengthening its oversight of online advertising and content under powers granted by the Online Safety and Media Regulation Act 2022.

Competitions & Promotions

Running a social media competition is a popular marketing tactic in Ireland — but there are specific legal requirements. Under Irish law, competitions with a prize must either be free to enter (with a free postal entry option if any other method involves a cost) or structured as a lottery with a licence. Key requirements include publishing clear and complete terms and conditions before the competition opens, setting a closing date, specifying who is eligible, and stating how winners will be notified. The CCPC monitors promotional practices and can investigate complaints.

Best Practice: Always have a solicitor review the terms of any major competition or promotion before it goes live. For day-to-day campaigns, the Matrix Internet team can advise on best-practice structuring — see our digital marketing services.

SEO & Content Marketing: Legal Pitfalls

Intellectual Property & Copyright

Using images, video, music, or text without the appropriate licence is a copyright infringement under the Copyright and Related Rights Act 2000. Irish courts have awarded damages in copyright infringement cases involving online use of images without licence. Always use licensed stock imagery, your own original content, or Creative Commons material (with attribution where required).

Defamation

The Defamation Act 2009 applies fully to online content published by Irish businesses. A social media post, blog article, or customer review response that makes a false statement of fact damaging to an individual’s or company’s reputation can result in legal action. Be particularly careful with competitor comparisons, negative commentary about individuals, and user-generated content published on your platforms (you may bear liability as publisher).

Misleading Advertising

Under the EU Misleading and Comparative Advertising Directive and Irish consumer law, making false or misleading claims about your products or services in any marketing material — including your website, Google Ads, or social media — is unlawful. The CCPC can investigate and impose penalties. Comparative advertising is permitted but must be factually accurate, non-denigrating, and like-for-like.

AI & Automated Marketing: Emerging Obligations

The EU AI Act, which entered into force in August 2024 with a phased rollout through 2025–2027, introduces new obligations for AI systems used in marketing contexts. While most Irish SMEs will not deploy high-risk AI systems as defined by the Act, several provisions are immediately relevant:

Transparency obligations: AI systems that interact with humans (chatbots, virtual assistants) must disclose that the person is talking to an AI — unless it is obvious from context. A chatbot on your website that appears human without disclosure likely violates the Act once its provisions apply to you.

Prohibited AI practices: The AI Act prohibits subliminal manipulation, exploitation of vulnerabilities, and social scoring. AI-driven personalisation that targets individuals based on inferred psychological vulnerabilities would fall foul of these provisions.

GDPR interaction: Any automated decision-making that has a significant effect on individuals (e.g., AI-driven credit decisions, personalised pricing) must comply with Article 22 GDPR, which gives individuals the right not to be subject to solely automated decisions without human oversight.
