SPAM FILTERS and SPAM TRAPS

Spam traps are inactive emails addresses that IPS after a certain inactivity period. The consequences for sending an email to these address are not very important. Your ESP will send you a bounce notification to let you know you’re sending emails to inactive email addresses, however, if you keep sending emails to hard bounces the ISP will maybe put you as a SPAM sender.
The second ISP’s barrier against spammer is spam filters. This is a program that prevents emails reaching inboxes by implementing different criteria such as unsolicited bulk mail and unwanted mail. Spam Traps analyst precisely your emails so be sure to write relevant and good content to reach the subscribers.
