Category 1 Bounces, though record as Hard Bounce, but still are temporary - would it be fine to actually exclude this category from exclusion lists (lists which have records with some negative filters - e.g. bounced, invalid, unsubscribed etc)
Hi Balkar, it looks like Marketo will set these category 1 hard bounces as Email Suspended = true which has an effect for 24 hours (though the field will never be changed back to false). Marketo won't try to send an email to these people during that 24-hour period, but will try on future emails after that time. Depending on how you're using the exclusion list, you could potentially put a filter for "Email Suspended at in past 24 hours" to capture people who are currently unemailable.
