Hard bounced emails

[Anonymous]

Hi, 

I sent a bulk of emails this morning. More then half Bounced back - Hard bounce. 
I decided to try to send those emails from my personal inbox - and it looks like emails are going through to their recipients. 
Why's that? Do you know what could happened? 
How can I retrieve those emails back in Marketo - so in the futire these emails won't bounce? 

Thanks 
Petra

Petra you should look at the "Email Invalid Cause".  This could be related to spam filters, among other things.

Hi Petra,

I think you should contact our deliverability team.  There could be a number of things going on.  Send me an email (abruckman@marketo.com) describing your issue and I can forward it to them.
