Spam traps are honeypots set by email providers to catch malicious senders of unsolicited emails.
Falling into a spam trap can lead to blacklisting, severely impacting email marketing campaigns.
Types of spam traps include pristine, recycled, and typo domain traps, each with unique characteristics.
Use double opt-in and avoid buying email lists to prevent spam traps and maintain a healthy email list.
Regularly clean your list and remove inactive users to reduce the risk of being labeled as spam.
