Internet Service Providers use SPAM traps to catch spammers. There are 2 types of SPAM traps:
- Recycled spam trap: Abandoned email addresses that haven’t been used for a long time. If you email these addresses, it means you are still emailing email addresses who didn’t open your last emails.
- Pristine spam trap, “honey pots”: These are email addresses displayed on some websites but they never been used to subscribe any email lists. If you email a honey pot email address it clearly shows ISP’s that your list contains email addresses that did not specifically request to receive an email from you, therefor your email is a SPAM.
To avoid SPAM traps, you must
- Never rent, purchase a list, or collect email addresses form the internet
- Monitor subscribers’ activity and remove inactive subscribers.
Can SPAM traps be removed by email verifiers?
SPAM traps are one of the highest value assets of Internet Service Providers. They will never publish, share, leak lists of their SPAM traps. If they do, it will not be used for performance tracking any more.
Be aware if an email verifier offers you to remove SPAM traps from your email lists they are misleading you! If SPAM traps were publicly available, they wouldn’t work anymore. No Internet Service Provider will ever share their SPAM traps with any email verifier, because it is against their business principles.
