The question of whether to use purchased email lists is a recurring one in the email marketing community. While the allure of quickly expanding your reach is strong, the consensus from industry experts, experienced marketers, and official documentation overwhelmingly points to this practice being highly detrimental to email deliverability and overall business health.
Key findings
Deliverability impact: Sending to purchased lists almost guarantees poor deliverability, with emails frequently landing in spam folders or being blocked entirely. This leads to a low email deliverability rate.
Reputation damage: High bounce rates, spam complaints, and hitting spam traps inherent in purchased lists severely damage your sender reputation and IP address.
Legal and compliance risks: Many purchased lists lack proper consent, violating regulations like GDPR and CAN-SPAM, leading to potential fines and legal issues.
Poor ROI: Despite the upfront cost, purchased lists rarely yield positive returns due to low engagement and high unsubscribe rates, making them a poor investment.
Key considerations
Build organically: Focus on permission-based list building through sign-up forms, content marketing, and lead magnets for sustainable growth. Mailchimp highlights reasons to never buy email lists.
Prioritise engagement: Engaged subscribers are key to good deliverability. Purchased lists generally consist of unengaged contacts who never opted in.
List hygiene: Regularly clean your email lists to remove inactive subscribers, bounces, and potential spam traps.
Recovery strategy: If you have used a purchased list, understand the steps needed to recover email deliverability.
What email marketers say
Email marketers often face pressure to achieve rapid growth, which can make purchasing email lists seem like an attractive shortcut. However, those with experience in the field consistently share a strong warning against this practice, having witnessed its negative repercussions firsthand on campaigns and sender reputation.
Key opinions
Damaged reputation: Marketers frequently report that using purchased lists immediately leads to poor domain and IP reputation. This makes it difficult to reach inboxes even with legitimate emails in the future.
Low engagement: The contacts on purchased lists have not opted in to receive your emails, resulting in exceptionally low open and click rates, and high unsubscribe rates. Twilio elaborates on why buying email lists harms deliverability.
Wasted resources: The time, effort, and money spent on sending to purchased lists are often wasted, as these campaigns rarely convert and can lead to account suspension by ESPs.
Spam trap exposure: Marketers quickly learn that purchased lists are riddled with spam traps, which are designed to identify senders of unsolicited email, causing severe blocklistings.
Key considerations
Consent is king: Focus on building a list of subscribers who have explicitly given permission to receive your emails. This ensures higher engagement and avoids compliance issues.
Segment your audience: Even with legitimate lists, proper segmentation and personalization are crucial for maximizing engagement and avoiding emails going to spam.
Understand the risks: Before considering a purchased list, marketers should fully grasp the risks and downsides of cold emailing to avoid severe deliverability consequences.
Alternative acquisition: Explore legitimate strategies like content upgrades, social media promotions, and lead generation campaigns to build high-quality lists.

What the experts say
Email deliverability experts universally condemn the use of purchased email lists. Their perspectives are rooted in a deep understanding of how Internet Service Providers (ISPs) and anti-spam systems evaluate sending practices and sender reputation. They emphasize the long-term, often irreversible, damage that can result from such a shortcut.
Key opinions
Catastrophic reputation harm: Experts agree that sending to purchased lists is one of the fastest ways to destroy a sender's reputation, leading to severe blocklisting and even domain blacklisting across major ISPs.
Spam trap activation: Purchased lists are notorious for containing various types of spam traps, which are traps designed to catch spammers. Hitting these traps can immediately trigger severe penalties.
Undermining authentication: Even with perfectly configured DMARC, SPF, and DKIM, poor sending practices with purchased lists will still lead to deliverability failure.
Costly recovery: Recovering from the reputation damage caused by purchased lists is a lengthy and challenging process, often requiring a complete rebuild of sending practices.
Key considerations
Long-term strategy: Experts advocate for a long-term approach to list building, focusing on quality subscribers over quantity, which is crucial for a healthy email domain reputation.
Proactive monitoring: Regularly monitor your sending reputation and blocklist status to catch and address issues before they escalate.
Compliance as a foundation: Adhering to anti-spam laws and respecting user consent is not just a legal requirement but a fundamental aspect of good deliverability.
Educate stakeholders: Educate sales and marketing teams on the severe risks of purchased lists to prevent misguided attempts at quick growth.
