Hello @CharleenA98 ,
To resend an email that was already sent to new contacts there's two different options I'd recommend. If those new contacts are part of the same list(s) that the email was originally sent to, you can do a manual resend to new contacts through the My Campaigns page. This will prompt our system to send the exact same email to those selected lists, but only target the contacts that have been added since. The other option would be to do a quicksend for each individual new contact, available through the Contacts dashboard page.
