Is renting a list safer than buying one?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
A vendor tells you their list is "rented, not sold" and that makes it totally above board. It sounds like a meaningful distinction. It isn't.
Whether you rent or buy, the core problem is the same: those people signed up to hear from that vendor, not from you. Their consent is with the list owner. You're a stranger showing up uninvited.
The vendor might argue they have permission to share their list for third-party sends. Even if that's technically true under a loose reading of CAN-SPAM, the recipients didn't agree to hear from you specifically. When your email lands, they don't recognize you. They mark it as spam. That complaint goes against your sender reputation, not the vendor's.
The practical outcomes of rented lists look a lot like the outcomes of purchased lists: low open rates, high complaint rates, possible blocklisting, and real damage to the domain you're trying to build a reputation on. (And under GDPR, "the vendor had permission" almost certainly doesn't cover consent for a third party to send marketing email. That's a separate legal basis.)
The only list worth emailing is one where people opted in directly to you. That's not a technicality. It's the whole point of permission-based email.
If your list feels thin right now, the fix is building it the right way, not renting a shortcut. We've seen it go badly enough times that it's worth being blunt about it.
