Buying email lists
Grey hat. Allowed in some places and easy to abuse. Check the rules first.
What is buying email lists?
Buying email lists is paying a vendor for a list of email addresses, often with names and company details, to use for marketing or sales emails. The people on the list did not opt in to hear from you.
Rules differ by country: B2B cold email to purchased contacts can be legal in the US under CAN-SPAM, while GDPR and similar laws set much stricter conditions. Most email marketing platforms ban purchased lists outright.
Why buying email lists matters
Bought lists are often stale and shared with many other buyers, so they bounce, hit spam traps and get marked as spam, which hurts deliverability for all your email.
Risks of buying email lists
- High bounce rates and spam traps that damage the sending domain.
- Email providers such as Mailchimp forbid purchased lists and can close the account.
- Under GDPR, emailing people who did not consent and have no relationship with you can be unlawful.
What to do instead of buying an email list
- Build a lead list yourself from public, relevant sources, matched to your ICP.
- Verify each address before sending.
- Send a small number of personal, relevant emails with an opt-out.
- Grow an opt-in list with a lead magnet.
