Marketo has built-in spam lead filtering for leads who fill out Marketo forms on your landing pages.  However, junk leads may still get into your Lead Database.  You can use a Smart List to find these junk leads or other leads who you might not want in your database.

Here are some examples of leads you might not want:

  • missing company name or last name
  • email address bounced
  • has a personal email address (like yahoo.com)

 

Say you want to find all leads who use a personal email address. You could build a Smart List that checks by using the Email Address and looks for leads whose email address contains a non-commercial domain:

After that, it's up to you how you want to handle those leads. You could:

  • ask them to provide a commercial email address (with an email, landing page, and form)
  • stop their emails with Marketing Suspended or Blacklisted (using Change Data Value)
  • delete those leads (using Delete Lead)

 

You can build similar Smart Lists to find potential junk leads such as:

  • undeliverable email addresses -- filter on Email Invalid is true

  • missing a company name -- filter on Company Name is empty
