Summary
Emailing a spam trap, which can be pristine or recycled addresses, leads to varied outcomes from bounces to successful delivery, but ultimately damages sender reputation and deliverability. This often results in blacklisting and can negatively impact your sending reputation across various platforms like Mailchimp, Microsoft, and Google. Effective mitigation involves a multi-faceted approach: improving list hygiene through verification, scrubbing, and removing invalid addresses; obtaining explicit permission through double opt-in; adhering to SMTP standards and sender guidelines; proactively monitoring email metrics; and focusing on better acquisition and engagement strategies. It is important to shift the perspective from complete elimination of spam traps to understanding and fixing gaps in consent and overall email sending practices when they are encountered.

Emailing a spam trap indicates a problem with email list hygiene and sender reputation. Hitting these addresses, which are used to identify and penalize spammers, can lead to blacklisting, reduced deliverability, and damage to your sender reputation. Mitigation strategies include proactive list cleaning (email verification, removing invalid emails, scrubbing lists), implementing double opt-in, avoiding purchased lists, monitoring bounce rates and feedback loops, and ensuring proper consent is obtained. A shift in perspective is also needed to understand that hitting a spam trap is an opportunity to improve consent collection and overall email sending practices.

Marketer view
Email marketer from Email Geeks explains that attempting to eliminate all spam traps is not useful. She suggests that instead understanding that hitting them is helpful and should give senders a chance to pause and understand if they are doing everything they can to prevent them from entering or remaining on your list. She explains that if spam traps are causing issues, there is likely a gap in how consent is collected and to try a repermission campaign.
