Adding additional leads to existing nurture campaign best practice
I started a nurture campaign for a specific industry with an initial list of leads. The product manager gave me an additional list of leads to add to that campaign. While I want to add them to this nurture campaign I don't want them just lost in Marketo because the only thing included in the spreadsheet is name, company and email address. When I import this second list, what is the best practice for importing them so they can be included in future campaigns - by adding the industry to the list of leads so I can filter them in future pulls?
