Hard Bounces

Every week I send to the same smart list that has not changed, however I still received almost the same number of  hard bounces and thousands of soft bounces. My question is why? Isn't Marketo supposed to automatically suppress hard bounces from the list and wouldn't this have been done in the first send? Although when I extract the report for the campaign, the lead activity type is Email Bounced for the bounced back email ids but the lead is not there in Marketo inbuilt list for Bounced Back Addresses.

Re: Hard Bounces

There are two categories of hard bounces:

Category 1: The recipient server bounced your email as spam or due to a blacklist.  The person record is marked as email suspended for 24 hours and then becomes eligible for emails again.

Category 2: The email address is invalid or doesn't exist.  Marketo automatically marks the record as "Email Invalid" and does not try to send to it again.

More info here Maintaining a Directory of Leads Bouncing Emails .  It sounds like your emails are hard bouncing as category 1.

Re: Hard Bounces

Hi,

hard bounces are not treated the same way, what has direct impact on ability to email a lead: Hard and Soft Bounces in Email - Marketo Docs - Product Documentation

Marketo won't automatically removed hard-bounced emails from the list; it just won't send some of them an email, while they will still remain in the list.
