17% bounce rate after using eMail Verifier

[Kareng]

I just sent my first campaign via MailChimp after using eMail Verifier to supposedly clean out bad addresses and was immediately suspended (albeit temporarily) due to a bounce rate of 17%, more than three times the allowed rate of 5%. Isn't eMail Verifier supposed to prevent this kind of outcome? What happened?

As the eMail Verifier sheet says, it can catch up to 70-80% bad emails, it is the best rate you can get with a Verifier nowadays. Do you have lots of Hotmail addresses in your list? Where did you get it? Did you purchase it?

No, I had almost no hotmail addresses. The list isn't purchased--it's from my own contacts.

Is there something is common with al bounces? Common domains?
