# Do I need to buy an email list?

**NO**—never

> Bought lists are consent-free by definition—spam traps, stale addresses, and people who've never heard of you. There is no faster way to torch a domain reputation.

Most verdicts on this site come with nuance. This one doesn't.

## Why this is a no, always

**Consent doesn't transfer.** Valid permission means the recipient clearly and knowingly agreed to receive *your* mail—freely given, specific, informed. A list assembled by someone else fails every part of that definition. If a pre-checked box or a terms-of-service clause doesn't count as consent (and it doesn't), an address purchased from a broker counts even less.

**The mechanics destroy you quickly.** Purchased lists are a package of everything inbox providers punish:

- **Stale addresses**—bounce rates spike, and past a few percent, providers read you as a spammer. (Above 4% is the classic danger line.)
- **Spam traps**—addresses that exist solely to catch senders who mail without permission. Hitting them can land your domain on blocklists like Spamhaus.
- **Recipients who never asked**—which means complaint rates far above the 0.3% ceiling Gmail and Yahoo enforce, from people encountering your brand for the first time as an intruder in their inbox.

**Your ESP will act before the providers do.** Sending to purchased lists violates essentially every email platform's acceptable use policy. High bounces and complaints from a bought list get accounts paused or terminated—the platform is protecting its shared infrastructure from you.

And the damage lands on your *domain*, which follows you to any provider you flee to afterward.

## What to do instead

Grow the boring way, which is also the only way that works: consent at the point of signup ([an unchecked, specific checkbox](https://resend.com/blog/how-to-properly-get-email-consent)), [double opt-in](https://doineed.email/double-opt-in) to prove it, content worth subscribing to. A thousand people who asked for your email outperform a hundred thousand who didn't—in revenue, not just in deliverability metrics.

If a vendor promises "verified, opted-in leads," ask: opted in to *whom*? Not to you. That's the entire problem.
