Hard Bounces - What to do

Hi Karina, as Runjini suggested you can create a smart list of everyone who hard bounced from your email campaign, select all, and then do a single data value change which can impact all 2100 in a single shot. 

Runjini, I will have to get back to you with more information about best practices surrounding deliverability, but one thread that might help is: https://community.marketo.com/MarketoDiscussionDetail?id=90650000000PxfdAAC

Karina, I am not sure about this, but perhaps you could pull the list of hard bounces based on which campaigns they bounced for, and then do some kind of flow step to mass change their values?  I've never done this before, but I've seen it posited as a solution for other similar issues.

Dory, other than what you suggest, are there any articles or help resources to address email deliverablity and smart campaigns to address them?  I need a step-by-step breakdown of how to do this, why to do this, and how it affects leads in the system.  All this information is so buried in Marketo's resource guides but it seems like a common campaign everyone else has set up.  Why isn't this a part of everyone's onboarding?

Since I have over 2100 leads, is there a way to handle this so I don't have to go in one-by-one and mark them as invalid/suspended?

Hi Karina, you can mark them as email invalid, or marketing suspended to ensure that they don't receive any additional emails. I would also advise setting up a smart campaign so that if a person's email address changes, email invalid (or marketing suspended, depending on how else you use the field) is unchecked to allow new emails to flow through if the person has corrected their email address.

Hope this helps!
