What is it?

"Recycled Spam Traps," also known as "Repurposed Spam Traps" or "Reactivated Spam Traps," are email addresses that were once valid but have been abandoned by their original owners and repurposed by email providers, ISPs or anti-spam organizations to identify senders with poor list hygiene practices or inadequate permission-based marketing practices.

Key points to remember

Key points to remember

  • Trap for Unwanted Senders: Recycled spam traps are designed to attract emails from senders who engage in unsolicited or non-permission-based email marketing practices, including purchasing email lists, scraping websites for addresses, or sending to inactive or outdated contacts.

  • Indicators of Poor Practices: Sending emails to recycled spam traps indicates to mailbox providers and anti-spam organizations that a sender's email list may be outdated, acquired through questionable means, or poorly managed, raising concerns about the sender's reputation and compliance with anti-spam regulations.


  • Deliverability Impact: Emails sent to recycled spam traps are typically considered unsolicited or unwanted, potentially triggering spam complaints, blocking or filtering by mailbox providers, or placement in the recipients' spam folders, negatively impacting sender reputation and deliverability.


  • List Hygiene Best Practices: To avoid the trap of recycled spam traps, senders should practice good list hygiene, including regularly removing inactive or unengaged subscribers, obtaining explicit consent for email communications, and maintaining updated contact information to ensure that emails reach only legitimate recipients.


  • Recovery and Remediation: If a sender's email list contains recycled spam traps or experiences deliverability issues due to poor list hygiene, remediation efforts may include list cleansing, subscriber reconfirmation campaigns, engagement-based segmentation, and adherence to best practices for permission-based marketing.
