Recipient Addresses hidden?

[LisaP2134]

Simple question, but I can't find the answer anywhere. I need to send an email via constant contact and I need to ensure that the recipients email addresses are a bcc - aka not visible. Can anyone definitely confirm whether the recipient emails are visible to one another? CC won't let me send a test email and googling it resulted in no answers and I searched within this community. Please help. This has to be a confidential process.

Hello @LisaP2134 ,

Emails sent through us are treated as though they're a standalone email directly sent from the assigned From Address to the contact's email address. CC'ing and BCC'ing are not functions for email sendouts, for a myriad of different reasons. Contacts would not be able to see others sent the email in any capacity.
