Invalid Email Addresses

[Samantha_Goldst]

I am trying to run a report to view bad emails within our Marketo instance, but I'm finding that an email could be listed as bad, but is not categorized as unsubscribed, invalid, or blacklisted, what other reason could there be for them being in a report?

Hi Samantha,

Other possible reasons for "bad emails":

marketing suspended, email suspended or hard bounced.

It really depends what you mean by "bad". Is this an internal designation that you've set up? Bounces would be the main thing I'd think of, but you'll want to dig in a little more and see what is marking them as bad.

Samantha,

I would run a smart list of bounced email addresses with the additional filters of "Email Suspended Cause" and "Email Invalid Cause" not contains "spam".

Sometimes an email marked spam will deliver a false positive and show as hard bounced, when indeed the email address is valid.

Hi Devraj,

That is actually not a false positive, it is by design.  There are two categories of Hard Bounce: Category 1 which is for spam blocks and Category 2 which is for invalid email addresses.  You can specify which category you wish to search for in the constraints menu, so for finding only invalid email addresses you would want to specify Category 2.

During our account setup, I created a group of smart lists on deliverability and list "health." The lists include:

• All Hard and Soft Bounces
• Customer Complaint Received by ISP
• Hard Bounce Category 1 - Spam
• Hard Bounce Category 2 - Email Invalid
• Hard Bounce Category 4 - Technical Issues
• Soft Bounces

If you haven't set these up, I'd suggest you do so you have a good foundation to look into the "bad emails" you refer to. Happy to show how these lists were built.

Hi Christina,

How did you know what subcategories were available for the email bounced filter? Nothing is coming up in my value selector. Nothing is in the product docs specifying subcategories. Could you point me to or list the types? Thanks so much!
