When a company is acquired or its operations cease and its assets, including email lists, are purchased, the question arises whether these lists can be legally reused for marketing purposes. The legality often depends heavily on the jurisdiction and the specific data protection laws in place, such as GDPR in Europe or CAN-SPAM in the US. While general business asset transfer typically includes customer data, the crucial aspect is whether the original opt-in consent transfers and if the new entity maintains the recipient's reasonable expectations regarding email content.
Key findings
Jurisdiction matters: Laws vary significantly, with GDPR and similar regulations imposing stricter requirements than CAN-SPAM in the US.
Asset transfer: Generally, a company acquisition includes all its assets, including customer goodwill and associated email permissions.
Transparency is key: In regions with strong data privacy laws, new owners have an obligation to inform data subjects of the change in ownership and their rights.
Original intent: The permissibility of reusing a list often hinges on whether the new owner's business aligns with the original reason for subscription.
Key considerations
Informing subscribers: It is best practice, and often legally required, to notify existing subscribers about the acquisition and the new entity's identity.
Opt-out mechanisms: Provide clear and accessible options for subscribers to adjust preferences or unsubscribe.
Compliance: Ensure adherence to relevant data protection laws (e.g., GDPR, CAN-SPAM, CCPA, CASL) to avoid legal repercussions and maintain email deliverability.
Relevance: Consider whether the new company's offerings are still relevant to the acquired list to prevent high complaint rates.
Unsubscribed contacts: Federal law (like CAN-SPAM) typically prohibits transferring an email address to a different list once it has unsubscribed from the first. This is a critical point for maintaining compliance, as highlighted by ISIPP.com.
Sender reputation: Mismanaging an inherited list can lead to increased spam complaints and negatively impact your sender reputation, potentially leading to blocklisting.
What email marketers say
Email marketers often prioritize deliverability and complaint rates, and their approach to inherited lists reflects these concerns. While the legal nuances are important, practical considerations about maintaining a good sender reputation and avoiding blocklists frequently guide their actions. They emphasize clear communication and respecting subscriber expectations to ensure a smooth transition and continued engagement.
Key opinions
ESPs and complaints: Many Email Service Providers (ESPs) allow list transfers as long as it does not generate excessive complaints.
Brand continuity: If the new owner continues to mail under the old brand or a very similar one, problems are less likely to occur.
Proactive communication: Marketers suggest sending an announcement email about the acquisition and the new ownership.
Opt-out management: Ensuring clear opt-out options are maintained is crucial for compliance and subscriber satisfaction.
Key considerations
Reputation risk: Abusing an inherited list can quickly lead to high spam complaint rates and damage sender reputation.
Expectations: The biggest risk comes from violating recipient expectations (for example, selling garden sheds to mouthwash subscribers).
List hygiene: Even if legally permissible, old or unmanaged lists may contain spam traps or inactive users, affecting deliverability.
Phased approach: Consider segmenting the list and sending re-engagement campaigns to gauge interest and minimize immediate deliverability impact, as suggested by Act!.
Marketer view
Marketer from Email Geeks notes that most ESPs will permit almost anything unless it directly results in complaints, suggesting that if mailing under the old brand, problems are unlikely.

What the experts say
Experts in email deliverability and privacy law stress the importance of understanding the specific legal framework of the jurisdiction, particularly when dealing with personal identifiable information (PII). They highlight that while business assets typically transfer, the nature of consent under modern privacy laws (like GDPR) is a critical factor that must be carefully managed to avoid legal pitfalls and maintain trust.
Key opinions
Jurisdictional differences: The legality of list reuse varies by jurisdiction; the US has different rules (for example, CAN-SPAM) than the UK/EU (GDPR).
PII transfer: In GDPR-equivalent countries, a change in legal entity (acquisition, merger) obliges the new owner to inform data subjects about the change and their rights regarding *all* PII, not just email addresses.
Transparency of consent: Experts emphasize that consent transfer is not automatic or hidden; it requires transparency and alignment with the original purpose of data collection.
Legitimate interests: New owners might have a legitimate interest to market to a list, but this right is conditional and must be balanced against recipients' rights and expectations.
Unsubscribed addresses: CAN-SPAM explicitly prohibits transferring an unsubscribed email address to a different list.
Key considerations
Proactive notification: Rather than waiting for enforcement, experts advise proactively notifying subscribers about the acquisition and providing clear options to manage preferences or opt-out.
Due diligence: The acquiring company should perform thorough due diligence to understand the data ownership and original terms of consent.
Recipient experience: Be mindful of the recipient's perspective, especially if the new business is significantly different from the old one, as this can lead to complaints.
State-specific laws: In the US, new state-level privacy laws (for example, CCPA, Virginia, Colorado) require careful consideration regarding data transfer and usage, impacting consent requirements.
Risk mitigation: Implementing transparent communication and clear opt-out processes is a strong strategy to reduce legal and reputational risk.

What the documentation says
Official documentation from regulatory bodies and legal analyses consistently emphasizes that company acquisitions do not automatically nullify privacy promises made to data subjects. The transfer of personal data, including email lists, is subject to the same data protection principles that govern initial collection and processing, requiring careful adherence to legal frameworks.
Key findings
Privacy promises endure: The Federal Trade Commission (FTC) states that "One company's purchase of another doesn't nullify the privacy promises made when the data was first collected."
Data transfer principles: The transfer of personal data during mergers and acquisitions (M&A) must adhere to the principles of data minimization, purpose limitation, and transparency.
Informing data subjects: Key regulations like GDPR mandate that individuals be informed when their personal data is transferred to a new controller, including the new identity and their rights.
Consent vs. legitimate interest: Depending on the legal basis for processing (for example, consent, legitimate interest), the requirements for transferring and reusing lists can vary significantly.
Key considerations
Legal due diligence: A comprehensive M&A due diligence checklist should include a thorough review of data privacy practices and consent records of the acquired company, as advised by The Harvard Law School Forum on Corporate Governance.
Update privacy policies: The acquiring company must update its privacy policy to reflect the new data handling practices and inform users.
Specific regulatory compliance: Beyond general principles, specific laws like CAN-SPAM and GDPR have explicit rules regarding opt-out mechanisms and data retention, which ISIPP provides guidance on.
Impact on deliverability: Regulatory non-compliance can lead to official complaints, fines, and severely impact email deliverability, potentially resulting in being added to blacklists.
Maintaining trust: Adhering to documentation guidelines not only ensures legal compliance but also helps maintain customer trust and a positive brand reputation.
