duplicate contacts in email blast

[AlyssaW27]

I have multiple contact lists, from different conferences. If I want to send an email blast to all my lists, will it recognize duplicate email addresses and only send one email, even if that name appears on multiple conference lists?

Hello @AlyssaW27 ,

If you send the email directly to those multiple lists, our system will be able to avoid sending multiple copies to any dupes across them all.
