Using an Email Bounced filter has a constraint for categories which seem to be numbers. Anyone know what those numbers mean?
Solved! Go to Solution.
According to this thread Bounce Category Numbers :
Category 1: Spam.
A receiving email server will return a Category 1 Hard Bounce when it regards the email as spam. Many times, this is a temporary bounce and sending to this server will be possible after 24 hours. When Marketo receives a Category 1 Hard Bounce, it will mark the lead as "Email Suspended". For 24 hours after this marking, Marketo will not send anymore emails to this lead. After 24 hours, sending can continue to this lead without any input from you.
Category 2: Does not Exist
A receiving email server will return a Category 2 Hard Bounce when the email address being sent to does not exist or is invalid. When Marketo receives this response, it will mark this lead as Email Invalid. No future emails will be sent to this lead unless this value is manually set back to false.
Category 3: Technical Issue
A receiving server will return Category 3 when they are experiencing some technical issues. No action is taken on our side for these bounces.

Question regarding Cat 2: if the email address is updated manually (e.g. via the CRM system), do I still need to manually update the Email Invalid with a value of FALSE to be able to send again? (So create e.g. a batch or smart campaign to do this).
We set up a workflow in Marketo to reset that value when the email address is changed (in either Marketo or Salesforce).
I noticed in our instance we also have a Category 4 and a Category 9. Do you know what those specifically mean?
Two years later I know, but in case anyone else finds this post and has the same question about Category 4 and Category 9 bounce categories.
According to the Optimizing Email Deliverability course:
Hope it helps someone
In Marketo, when an email is sent to an address and is returned as undeliverable, this is known as a bounce. Bounces can occur for a variety of reasons, such as an invalid email address or an email server being down. Marketo categorizes bounces into two main types:
Hard Bounces: These are permanent delivery failures, such as bounces are emails that have been marked as spam bythe recipient mail server.
Soft Bounces: These are temporary delivery failures, such as when an email server is down or the recipient's inbox is full. Soft bounces are generally caused by a temporary error, and the email may be delivered later.
In addition to these two main categories, Marketo also allows for additional specific types of bounces:
Block Bounces: These are bounces caused by the email being blocked by an organization's email security gateway, for example for the email containing some unwanted content
Challenge response Bounces: These are bounces caused by a recipient's email client responding with a challenge, or request for confirmation, before accepting the email
It's important to monitor bounces and take appropriate action, such as removing invalid email addresses from your list or resending the email later. By keeping track of bounce rates and identifying the cause of the bounces, you can improve your email deliverability and ensure that your messages are reaching the right people.
Marketo allows you to download a bounce report, which you can use to identify the specific email addresses that bounced, the reason for the bounce, and the number of bounces per type. With this information, you can identify patterns and make the necessary changes in your email strategy.
Also
Hard Bounces come in two types, Category 1 and Category 2.
Soft Bounces come in three different types, Categories 3, 4 or 9.
Soft Bounces: These are temporary delivery failures, such as when an email server is down or the recipient's inbox is full. Soft bounces are generally caused by a temporary error, and the email may be delivered later.
The same email send will never be delivered later because the retry period is over. It's possible that repeating the same send in the future will succeed, if the problem was entirely with the remote server.
However, it's a bit of a misnomer to say Soft Bounces are truly "temporary".
They're both typos, neither of which will resolve itself. Yet one is Soft and one is Hard.
