Will marketo send the same email twice to the same contact?

[Anonymous]

I just sent an email out and afterwards was asked to broaden the list criteria.  If I schedule it again with the larger list, will marketo know not to send that same email twice to contacts included on the first smart list? Or should I filter out any criteria from the first smart list?

Hi Elliott,

It's not available, and I wish it was :(.  I'm thinking hypothetically what if that was available.  Sorry if I caused any confusion.

Michelle, where in Admin would you set such a rule?

What if in admin you set a rule where there's a limit of one email that a lead can receive per day?  Would there be a chance that the lead can get the email twice?

Thanks Elliott!

Marketo will send the email again unless you add the Not Was Sent Email filter.
