How many times does an email need to soft bounce before it is marked as invalid?

[Anonymous]

Hi there,

Does anyone know how many times an email needs to soft bounce until it is marked as invalid?

We are seeing email addresses such as 1@1.com being marked as a soft bounce multiple times. To me it seems as though it should be marked as a soft bounce right away.

Thanks!

This is excellent!  I was about to post a discussion on the same topic.  Thank you, Nichole, for asking the question, and thanks to Kim, Dory and Jep for answering so thoroughly.  🙂

I fixed the link to the PDF: email deliverability analysis and optimization

Hi Nichole, let me know if you'd be interested in the PDF referenced in the second link that Kim posted above. Unfortunately, Marketo won't let me post it here. My email is dviscogliosi@emarketer.com

And to answer your question, Marketo won't mark 1000 soft bounces as invalid. You'd have to set up a rule on your own that would mark email invalid after x number of bounces.
