Help emailing my whole database minus one list, and dealing with a suppression file

[Anonymous]

I'm trying to send an email to nearly every lead in our database except for one smaller list of leads that's already in the database. I also want to upload a list of email addresses to use as a suppression file. What is the best way to go about this? 

Is there a way to set up a smart list for all leads in the database except X, for example? 

How should I apply the suppression? Should I import the emails into a list and then run a Smart List to filter them out? And will Marketo automatically add these email addresses as new leads in my database (assuming the emails aren't already in the database)? Is there a way to tell Marketo NOT to add them? I don't want them to be created as leads, if this is possible, cause down the road we may want to email the whole database again but not these contacts.

I'd add them to a list in the lead database and label it as suppression; then build your smartlist for the send. Marketo will add them to your database since you're uploading them. Another alternative would be to run a smart campaign and mark these people as 'suspended' which will automatically remove them from every subsequent send.

Thanks Kristen. Can you explain how I add the suppression file to a list in the lead database and label it as a suppression? If I do this, and later build a smartlist for a new send to the whole database, will the smart list automatically exclude the leads labeled suppression?

You can either run the list through a smart campaign with the flow step of "marketing suspended" or just remember to add member of list not in "    " for every send. Since it sounds like this is an on-going suppression list, you should probably just mark them as suspended so you don't have to remember to remove them every time.
