Blind emails are a way to allow members to email one another without providing their email address publically on the app. The user only sees the member’s name when sending the email, not their email address.
Once the receiver of the email receives it, they then have the option if they want to share their email address with the sender. They would share their email address with the sender by replying back to the original email.
Once the original email is sent through the app, the rest of the conversation takes place completely outside of the app and in the users’ email inboxes. When users add a Member to their Address Book it would not save the email address to the device’s native Address Book.
