Hard bounced

Hi everyone,

Our send list is ~ 200,000 and we always get hard bounce in the range of 2000- 2500 and soft bounce around 600.

I am already suppressing all these fields ( with ANY logic) -

1. "Email Invalid" TRUE

2. "Black Listed" TRUE
3. "Unsubscribed" TRUE
4. "Email Suspended" TRUE

5. "Marketing Suspended" TRUE

6. "Email address is EMPTY

7. Email bounced is any in past 30 days, minimum number of times 2 ( our cadence is twice a week)

8. Email bounced soft is any in past 30 days, minimum number of times 2

Even after suppressing all these fields, we are always getting hard bounce ( 2000-2500) and soft bounce( 600).

Question- Am I missing any Marketo field which I need to add in my suppression list? What else could be done to clean up the data? How I can get the report about which email addresses are getting always hard bounced?
