* At Bouncer, we believe that spam traps are an important part of the email ecosystem. Additionally, it’s impossible to provide precise information about the spam traps as the really good ones are not publicly known. That’s why we prefer to provide information about the toxicity of email addresses instead of just pointing out spam traps. The higher Toxicity Score is, the higher probability of hitting a spamtrap or other malicious and harmful email address.

"After using several other email verification services (some that have been considered to be premium with a premium price), The accuracy is by far the best. Not just in pin pointing whether an email is valid or undeliverable but using additional catagoties such as temporary email addresses and emails that run the risk of damaging my sender score for numerous reasons - I have not found this kind..."
