How can I identify the cause of soft bounces that don't fall in category 3,4 or 9
Hi,
I have 161 soft bounces of which 119 I've identified as falling under category 3, 4 & 9 however, for the remaining 42 how can I find out why they soft bounced? are there other soft bounce categories which I can use?
Link to marketo docs for soft bounce categories: https://nation.marketo.com/t5/knowledgebase/maintaining-a-directory-of-leads-bouncing-emails/ta-p/300838
Thanks!
