Spam Traps
Spam traps, also called "honeypots", are email addresses created (or re-activated) by ISPs specifically to lure spammers. In many cases, the only way to acquire the address is through an automated email address harvesting process.

If you discover spam that was sent by a SendGrid customer, please report it to our team. We appreciate your help in keeping our email stream clean.
Spam traps are important because so many large ISPs, spam filter providers, and Domain Name System deny lists use them. In short, sending an email to a spam trap can lead directly to being blocked by the organization that set up the trap. Remember that blocking can ruin a business's reputation and halt further email deliverability.
