Why are there still hard bounces?

[Anonymous]

Every week I send to the same smart list that has not changed, however I still received 200+ hard bounces and thousands of soft bounces. My question is why? Isnt Marketo supposed to automatically supress hard bounces from the list and wouldnt this have been done in the first send? I would guess the same question applies to soft bounces as well. Has anyone else found a solution?

Thanks

Marketo will mark a lead as suspended after trying a number of times for hard bounces. Are you seeing the same email address bounce repeatedly in sends? Soft bounces will continue to occur unless the email is finally rejected. Here are more details: https://community.marketo.com/MarketoArticle?id=kA050000000KzZyCAK
