Spam traps are a method used by major Internet Service Providers (ISPs) and blacklist providers to identify spammers and hurt their deliverability. A spam trap looks like a real email address, but it doesn't belong to a real person and can't be used for any kind of communication. These addresses will never open, never bounce, and (once allowed on your list) will continue to negatively affect your deliverability at that domain. There are two types of Spam Traps: Pristine and Recycled. There is another category which is often referred to as a typo trap.
Once a trap makes it onto your list, they are notoriously hard to find (they are designed to prevent spammers from easily removing them from their lists). Through both Validity and SNDS (Smart Network Data Services), emfluence tracks spam traps hit on the platform's IP. Each will provide a date of the spam trap hit. Validity includes all domains while SNDS' list covers only Microsoft domains (such as outlook.com, hotmail.com, msn.com and live.com). Once a spam trap has been hit, the best course of action is to do a list cleanse to find and suppress the trap from ever receiving email again.When cleansing a list, any known dangerous addresses such as bots, traps, and the like will be placed in the blacklist file. Our provider suggest these should be suppressed within your account. You can learn more about list cleanses here.
