Avoid Buying Email Lists

In today’s digital landscape, email marketing remains one of the most effective ways to reach your target audience. However, building a high-quality email list can be a challenging and time-consuming process. Some marketers may be tempted to take shortcuts by buying or renting third-party email lists. But beware! This practice not only poses serious risks to your reputation and deliverability, but it may also expose you to potential legal and financial consequences.

In this blog post, we’ll discuss the dangers of buying or renting third-party email lists and why co-marketing is a smarter, more compliant alternative for growing your email marketing reach.

The Risks of Buying Email Lists

Legal Consequences: GDPR and CPRA

Buying or renting email lists puts you at risk of violating privacy laws such as the General Data Protection Regulation (GDPR) in the European Union and the California Privacy Rights Act (CPRA). These regulations require that individuals give informed consent before their personal information can be collected, processed, or shared. When you purchase an email list, you have no way of knowing if the people on that list have given informed consent for their data to be used by you.

Violating GDPR or CPRA can result in significant fines and lawsuits, damaging your brand’s reputation and bottom line. Fines under GDPR can reach up to 4% of a company’s global annual turnover or €20 million, whichever is higher. CPRA fines can be up to $7,500 per violation. With such high stakes, it’s crucial to prioritize compliance when building your email marketing list.

Poor List Quality

When you buy or rent an email list, there’s no guarantee that the data you receive will be of high quality. Many third-party email lists are riddled with outdated or inaccurate information, fake addresses, and spam traps. This can hurt your email deliverability, as high bounce rates and spam complaints can lead to your messages being flagged by email service providers (ESPs) and landing in the dreaded spam folder.

Furthermore, low-quality email lists often contain recipients who have no interest in your products or services. This can lead to poor open rates, low engagement, and ultimately, a negative return on investment (ROI) for your email marketing efforts.

Lack of Informed Consent

As mentioned earlier, informed consent is a cornerstone of privacy laws like GDPR and CPRA. When you buy or rent an email list, you have no way of verifying if the individuals on that list have given their informed consent to receive marketing messages from you. Sending unsolicited emails to people who haven’t opted in can damage your sender reputation and lead to spam complaints, making it more difficult for your emails to reach the inboxes of your legitimate subscribers.

A Better Alternative: Co-Marketing

Given the risks associated with buying or renting third-party email lists, it’s essential to explore more compliant and effective ways to grow your email marketing reach. Co-marketing offers an attractive alternative that allows you to partner with another company or organization to leverage their established audience.

In a co-marketing arrangement, you purchase a sponsorship to someone else’s email list, and they send your email to their audience, promoting an offer or opt-in opportunity. This ensures that the recipient has already provided informed consent to receive marketing messages from the list owner, making your campaign compliant with privacy laws like GDPR and CPRA.

Benefits of Co-Marketing

Compliance with Privacy Laws

Co-marketing ensures that you’re sending emails to individuals who have given their informed consent, as required by privacy regulations. This helps you avoid costly fines and lawsuits while maintaining your reputation as a responsible marketer.

Better Targeting and Engagement

When you engage in co-marketing, you have the opportunity to partner with companies that share a similar target audience or complementary products and services. This ensures that your message reaches a more relevant and engaged audience, which can lead to higher open rates, click-through rates, and conversions.

Improved Sender Reputation and Deliverability

Co-marketing allows you to send your emails through a reputable and established partner, which can positively impact your sender reputation. As a result, your emails are more likely to reach the inbox of your intended recipients, improving overall deliverability and campaign performance.

Relationship Building

Co-marketing partnerships can help you forge valuable relationships with other companies in your industry, fostering collaboration and mutual growth. These relationships can lead to future marketing opportunities, resource sharing, and valuable industry insights.


While the allure of buying or renting third-party email lists may seem tempting, the risks far outweigh the potential benefits. Not only can you face serious legal and financial consequences for violating privacy laws like GDPR and CPRA, but the quality of the lists and lack of informed consent can lead to poor campaign performance and damage to your sender reputation.

By choosing co-marketing instead, you can partner with reputable companies to reach a more targeted, engaged audience while staying compliant with privacy regulations. This approach not only ensures better deliverability and campaign performance but also helps you build valuable relationships within your industry. As a smart marketer, it’s essential to prioritize compliance and long-term success over short-term gains, and co-marketing offers an attractive and responsible path forward.
